Nature of Operations [Abstract]
Nature of Operations [Text Block]	Note 1. Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X for interim financial information. All normal recurring adjustments considered necessary for a fair presentation have been included. Certain disclosures normally included in annual consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States (U.S. GAAP) have been omitted. These consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes contained in our annual report on Form 10-K for the year ended March 31, 2015 . Unless the context otherwise requires, references to "Sprint," "we," "us," "our" and the "Company" mean Sprint Corporation and its consolidated subsidiaries for all periods presented, and references to "Sprint Communications" are to Sprint Communications, Inc. and its consolidated subsidiaries. The preparation of the unaudited interim consolidated financial statements requires management of the Company to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and the disclosure of contingent assets and liabilities at the date of the unaudited interim consolidated financial statements. These estimates are inherently subject to judgment and actual results could differ. Certain prior period amounts have been reclassified to conform to the current period presentation.

New Accounting Pronouncements

New Accounting Pronouncements	3 Months Ended
	Jun. 30, 2015
Accounting Policies [Abstract]
New Accounting Pronouncements and Changes in Accounting Principles [Text Block]	In April 2014, the Financial Accounting Standards Board (FASB) issued authoritative guidance regarding Reporting of Discontinued Operations and Disclosures of Disposals of Components of an Entity , which changes the criteria for determining which disposals can be presented as discontinued operations and modifies related disclosure requirements. The updated guidance defines discontinued operations as a disposal of a component or group of components that is disposed of or is classified as held for sale and represents a strategic shift that has, or will have, a major effect on an entity’s operations and financial results. Additionally, the disclosure requirements for discontinued operations were expanded and new disclosures for individually significant dispositions that do not qualify as discontinued operations are required. The guidance is effective prospectively for fiscal years and interim reporting periods within those years beginning after December 15, 2014, with early adoption permitted for transactions that have not been reported in financial statements previously issued or available for issuance. The standard is effective for the Company's fiscal year beginning April 1, 2015 and will be applied to relevant transactions. In May 2014, the FASB issued new authoritative literature, Revenue from Contracts with Customers. The issuance is part of a joint effort by the FASB and the International Accounting Standards Board (IASB) to enhance financial reporting by creating common revenue recognition guidance for U.S. GAAP and International Financial Reporting Standards and, thereby, improving the consistency of requirements, comparability of practices and usefulness of disclosures. The new standard will supersede much of the existing authoritative literature for revenue recognition. In July 2015, the FASB deferred the effective date of this standard. As a result, the standard and related amendments will be effective for the Company for its annual reporting period beginning April 1, 2018, including interim periods within that reporting period. Early application is permitted, but not before the original effective date of April 1, 2017. Entities are allowed to transition to the new standard by either retrospective application or recognizing the cumulative effect. The Company is currently evaluating the guidance, including which transition approach will be applied and the estimated impact it will have on our consolidated financial statements. In June 2014, the FASB issued authoritative guidance regarding Compensation - Stock Compensation , which provides guidance on how to treat performance targets that can be achieved after the requisite service period. The updated guidance requires that a performance target that affects vesting and could be achieved after the requisite service period be treated as a performance condition and accounted for under current guidance as opposed to a nonvesting condition that would impact the grant-date fair value of the award. The guidance is effective for annual periods and interim periods within those annual periods beginning after December 15, 2015 with early adoption permitted. Entities may apply the amendments either (i) prospectively to all awards granted or modified after the effective date; or (ii) retrospectively to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented in the financial statements and to all new or modified awards thereafter with the cumulative effect as an adjustment to the opening retained earnings balance as of the beginning of the earliest annual period presented. The Company does not expect the adoption of this guidance to have a material effect on our consolidated financial statements. In August 2014, the FASB issued authoritative guidance regarding Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern , which requires management to assess an entity’s ability to continue as a going concern and to provide related footnote disclosures in certain circumstances. The updated guidance requires management to perform interim and annual assessments on whether there are conditions or events, considered in the aggregate, that raise substantial doubt about an entity’s ability to continue as a going concern within one year after the date that the financial statements are issued and to provide related disclosures, if required. The standard will be effective for the Company’s fiscal year ending March 31, 2017, although early adoption is permitted. The Company does not expect the adoption of this guidance to have a material effect on our consolidated financial statements. In January 2015, the FASB issued authoritative guidance on Extraordinary and Unusual Items , eliminating the concept of extraordinary items. The issuance is part of the FASB’s initiative to reduce complexity in accounting standards. Under the current guidance, an entity is required to separately classify, present and disclose events and transactions that meet the criteria for extraordinary classification. Under the new guidance, reporting entities will no longer be required to consider whether an underlying event or transaction is extraordinary, however, presentation and disclosure guidance for items that are unusual in nature or occur infrequently was retained and expanded to include items that are both unusual in nature and infrequently occurring. The amendments are effective for the Company’s fiscal year beginning April 1, 2016, although early adoption is permitted if applied from the beginning of a fiscal year. The Company does not expect the adoption of this guidance to have a material effect on our consolidated financial statements. In February 2015, the FASB issued authoritative guidance regarding Consolidation , which provides guidance to management when evaluating whether they should consolidate certain legal entities. The updated guidance modifies evaluation criteria of limited partnerships and similar legal entities, eliminates the presumption that a general partner should consolidate a limited partnership, and affects the consolidation analysis of reporting entities that are involved with variable interest entities, particularly those that have fee arrangements and related party relationships. All legal entities will be subject to reevaluation under the revised consolidation model. The standard will be effective for the Company’s fiscal year beginning April 1, 2016, including interim reporting periods within that fiscal year, although early adoption is permitted. The Company is currently evaluating the newly issued guidance and assessing the impact it will have on our consolidated financial statements. In April 2015, the FASB issued authoritative guidance regarding Interest - Imputation of Interest, which requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The guidance is effective for fiscal years and interim reporting periods within those years beginning after December 31, 2015, with early adoption permitted. The standard will be effective for the Company’s fiscal year beginning April 1, 2016. The Company does not expect the adoption of this guidance to have a material effect on our consolidated financial statements. In July 2015, the FASB issued authoritative guidance regarding Inventory , which simplifies the subsequent measurement of certain inventories by replacing today’s lower of cost or market test with a lower of cost and net realizable value test. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The guidance is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years, although early adoption is permitted. The standard will be effective for the Company’s fiscal year beginning April 1, 2017. The Company does not expect the adoption of this guidance to have a material effect on our consolidated financial statements.

Accounts Receivable Facility

Receivables [Abstract]
Financing Receivables [Text Block]	Note 3. Accounts Receivable Facility Transaction Overview On May 16, 2014, certain wholly-owned subsidiaries of Sprint entered into a two -year committed facility (Receivables Facility) to sell certain accounts receivable (the Receivables) on a revolving basis, subject to a maximum funding limit. The Receivables Facility was amended in April 2015, which extended the expiration date to March 31, 2017 and increased the maximum funding limit to $3.3 billion , of which $1.4 billion was available as of June 30, 2015 . The available funding varies based on the amount of eligible receivables (as defined in the Receivables Facility). In connection with the Receivables Facility, Sprint formed wholly-owned subsidiaries that are bankruptcy-remote special purpose entities (SPEs). Pursuant to the Receivables Facility, certain Sprint subsidiaries (Originators) transfer Receivables to the SPEs. Receivables contributed by the Originators to the SPEs and available to be sold to the unaffiliated multi-seller asset-backed commercial paper conduits (Conduits) and other financial institutions (together with the Conduits, "Investors") primarily consisted of installment receivables and wireless service charges due from subscribers. The SPEs then may sell the Receivables to a bank agent on behalf of the Investors or their sponsoring banks. Sales of eligible Receivables by the SPEs, once initiated, generally occur daily and are settled on a monthly basis. Sprint pays a fee for the drawn and undrawn portions of the Receivables Facility. A subsidiary of Sprint services the Receivables in exchange for a monthly servicing fee, and Sprint guarantees the performance of the servicer's and the Originator's obligations under the Receivables Facility. The fees associated with the Receivables Facility are recognized in selling, general and administrative expenses on the consolidated statements of comprehensive (loss) income. Receivables sold to the Investors are treated as a sale of financial assets. Upon sale, Sprint derecognizes the Receivables, as well as the related allowances, and recognizes the net proceeds received in cash provided by operating activities. The difference between the Receivables sold and the cash received, which represents a financial asset due to Sprint from the Investors, is referred by us as the deferred purchase price (DPP). The DPP is realizable by Sprint contingent upon the cash collections on all of the Receivables sold to the Investors. The DPP is classified as a trading security within "Prepaid expenses and other current assets" on the consolidated balance sheet and is recorded at its estimated fair value. The fair value of the DPP is estimated using a discounted cash flow model, which relies principally on unobservable inputs such as the nature of the sold Receivables and subscriber payment history. Changes in the fair value of the DPP are recognized in operating income on the consolidated statements of comprehensive (loss) income. On March 31, 2015, of the $3.5 billion of Receivables contributed by the Originators to the SPEs, the SPEs sold approximately $1.8 billion of service Receivables to the Investors in exchange for $500 million in cash (reflected within the change in accounts and notes receivable on the consolidated statement of cash flows) and a DPP of $1.3 billion , with an estimated fair value of $1.2 billion . In accordance with its rights under the Receivable Facility and to facilitate the execution of the April 2015 amendment discussed above, in April 2015 Sprint elected to temporarily suspend sales of receivables by the SPEs to the Investors and remitted payments received to the Investors to reduce the funded amount to zero. As of June 30, 2015 , the amount of the Receivables held by the SPEs and the estimated fair value of the DPP due from Investors was $3.4 billion and $14 million , respectively. Each SPE’s sole business consists of the purchase or acceptance through capital contributions of the Receivables from the Originators and the subsequent retransfer of, or granting of a security interest in, such Receivables to the bank agent under the Receivables Facility. In addition, each SPE is a separate legal entity with its own separate creditors who will be entitled, prior to and upon the liquidation of the SPE, to be satisfied out of the SPE’s assets prior to any assets or value in the SPE becoming available to the Originators or Sprint. Accordingly, the assets of the SPE are not available to pay creditors of Sprint or any of its affiliates (other than any other SPE), although collections from these receivables in excess of amounts required to pay the investment, yield and fees of the Investors and other creditors of the SPEs may be remitted to the Originators and Sprint during and after the term of the Receivables Facility. Continuing Involvement Sprint has continuing involvement in the Receivables sold by the SPEs to the Investors because a subsidiary of Sprint services the receivables. Additionally, in accordance with the Receivables Facility, Sprint is required to repurchase aged receivables, or those that will be written off in accordance with Sprint's credit and collection policies, both of which result from subscriber non-payment. Sprint recognizes assets and liabilities, as applicable, with respect to its continuing involvement at fair value. Sprint's continuing involvement did not have a material impact on its financial statements as of June 30, 2015 . Variable Interest Entity Sprint determined the Conduits are considered variable interest entities because they lack sufficient equity to finance their activities. Sprint's interest in the Receivables purchased by the Conduits, which is comprised of the net receivable due to Sprint, is not considered variable interest because it is in assets that represent less than 50% of the total activity of the Conduits. Installment Receivables Certain subscribers have the option to purchase their devices in installments up to a 24 -month period. Short-term installment receivables are recorded in "Accounts and notes receivable, net" and long-term installment receivables are recorded in "Other assets" in the consolidated balance sheets. The following table summarizes the installment receivables: June 30, March 31, (in millions) Installment receivables, gross $ 1,566 $ 1,725 Deferred interest (115 ) (139 ) Installment receivables, net of deferred interest 1,451 1,586 Allowance for credit losses (217 ) (190 ) Installment receivables, net $ 1,234 $ 1,396 Classified on the consolidated balance sheets as: Accounts and notes receivable, net $ 976 $ 1,035 Other assets 258 361 Installment receivables, net $ 1,234 $ 1,396 The balance and aging of installment receivables on a gross basis by credit category were as follows: June 30, 2015 March 31, 2015 Prime Subprime Total Prime Subprime Total (in millions) Unbilled $ 1,125 $ 330 $ 1,455 $ 1,243 $ 359 $ 1,602 Billed - current 53 19 72 65 22 87 Billed - past due 23 16 39 21 15 36 Installment receivables, gross $ 1,201 $ 365 $ 1,566 $ 1,329 $ 396 $ 1,725 Activity in the deferred interest and allowance for credit losses for the installment receivables is as follows: Three Months Ended June 30, Twelve Months Ended March 31, 2015 2015 (in millions) Deferred interest and allowance for credit losses, beginning of period $ 329 $ 124 Bad debt expense 81 398 Write-offs, net of recoveries (54 ) (255 ) Change in deferred interest on short-term and long-term installment receivables (24 ) 62 Deferred interest and allowance for credit losses, end of period $ 332 $ 329

Fair Value Disclosures [Abstract]
Financial Instruments	Note 5. Financial Instruments The carrying amount of cash and cash equivalents, accounts and notes receivable, and accounts payable approximates fair value. Short-term investments (consisting primarily of commercial paper), totaling approximately $203 million and $166 million as of June 30, 2015 and March 31, 2015 , respectively, are recorded at amortized cost, and the respective carrying amounts approximate fair value primarily using quoted prices in active markets. The fair value of marketable equity securities totaling $58 million and $40 million as of June 30, 2015 and March 31, 2015 , respectively, are measured on a recurring basis using quoted prices in active markets. The estimated fair value of the majority of our current and long-term debt, excluding our credit facilities, is determined based on quoted prices in active markets or by using other observable inputs that are derived principally from, or corroborated by, observable market data. The following table presents carrying amounts and estimated fair values of current and long-term debt: Carrying amount at June 30, 2015 Estimated Fair Value Using Input Type Quoted prices in active markets Observable Unobservable Total estimated fair value (in millions) Current and long-term debt $ 33,759 $ 26,216 $ 4,885 $ 1,756 $ 32,857 Carrying amount at March 31, 2015 Estimated Fair Value Using Input Type Quoted prices in active markets Observable Unobservable Total estimated fair value (in millions) Current and long-term debt $ 33,434 $ 27,238 $ 4,906 $ 1,410 $ 33,554

At the end of the lease term, the subscriber has the option to turn in their device, continue leasing their device, or purchase the device. As of June 30, 2015 , substantially all of our device leases were classified as operating leases. At lease inception, the devices leased through Sprint's direct channels are reclassified from inventory to property, plant and equipment. For those devices leased through indirect channels, Sprint purchases the device to be leased from the retailer at lease inception. The devices are then depreciated using the straight-line method to their estimated residual value at the end of the lease term. The following table presents leased devices and the related accumulated depreciation: June 30, March 31, (in millions) Leased devices $ 3,279 $ 1,974 Less: accumulated depreciation (450 ) (197 ) Leased devices, net $ 2,829 $ 1,777 During the three-month period ended June 30, 2015 , there were non-cash transfers to leased devices of approximately $808 million along with a corresponding decrease in "Device and accessory inventory." Non-cash accruals included in leased devices totaled approximately $207 million as of June 30, 2015 for devices purchased from indirect dealers that were leased to our subscribers.

Goodwill and Intangible Assets Disclosure [Abstract]
Intangible Assets	Note 7. Intangible Assets Indefinite-Lived Intangible Assets Our indefinite-lived intangible assets consist of FCC licenses, which were acquired primarily through FCC auctions and business combinations, certain of our trademarks, and goodwill. At June 30, 2015 , we held 1.9 GHz, 800 MHz and 2.5 GHz FCC licenses authorizing the use of radio frequency spectrum to deploy our wireless services. As long as the Company acts within the requirements and constraints of the regulatory authorities, the renewal and extension of these licenses is reasonably certain at minimal cost. Accordingly, we have concluded that FCC licenses are indefinite-lived intangible assets. Goodwill represents the excess of consideration paid over the estimated fair value of net tangible and identifiable intangible assets acquired in business combinations.

As of June 30, 2015 , Sprint Corporation, the parent corporation, had $10.5 billion in aggregate principal amount of senior notes outstanding. In addition, as of June 30, 2015 , the outstanding principal amount of senior notes issued by Sprint Communications, Inc. and Sprint Capital Corporation, guaranteed notes issued by Sprint Communications, Inc., exchangeable notes issued by Clearwire Communications LLC, the EDC agreement, and the secured equipment credit facilities, totaling $21.9 billion in principal amount of our long-term debt issued by 100% owned subsidiaries, was fully and unconditionally guaranteed by Sprint Corporation. The indentures and financing arrangements governing certain of our subsidiaries' debt contain provisions that limit cash dividend payments on subsidiary common stock. Except in the case of notes issued by and secured by assets of Clearwire Communications LLC, the transfer of cash from subsidiaries to the parent corporation generally is not restricted. Cash interest payments, net of amounts capitalized of $15 million and $12 million , totaled $613 million and $615 million during the three-month periods ended June 30, 2015 and 2014 , respectively. Notes As of June 30, 2015 , our outstanding notes consisted of senior notes, guaranteed notes, and exchangeable notes, all of which are unsecured, as well as secured notes of Clearwire Communications LLC, which are secured solely by assets of Clearwire Communications LLC and certain of its subsidiaries. Cash interest on all of the notes is generally payable semi-annually in arrears. As of June 30, 2015 , $30.1 billion aggregate principal amount of the notes was redeemable at the Company's discretion at the then-applicable redemption prices plus accrued interest. As of June 30, 2015 , approximately $21.6 billion aggregate principal amount of our senior notes and guaranteed notes provide holders with the right to require us to repurchase the notes if a change of control triggering event (as defined in the applicable indentures and supplemental indentures) occurs. As of June 30, 2015 , $300 million aggregate principal amount of Clearwire Communications LLC notes provide holders with the right to require us to repurchase the notes if a change of control occurs (as defined in the applicable indentures and supplemental indentures). If we are required to make such a change of control offer, we will offer a cash payment equal to 101% of the aggregate principal amount of notes repurchased plus accrued and unpaid interest. Upon the close of the acquisition of Clearwire Corporation, the Clearwire Communications, LLC 8.25% Exchangeable Notes due 2040 became exchangeable at any time, at the holder’s option, for a fixed amount of cash equal to $706.21 for each $1,000 principal amount of notes surrendered. As a result, $444 million , which is the total cash consideration payable upon an exchange of all $629 million principal amount of notes outstanding, is now classified as a current debt obligation. The remaining carrying value of these notes is classified as a long-term debt obligation. Credit Facilities Bank credit facility The Company has a $3.3 billion unsecured revolving bank credit facility that expires in February 2018. Borrowings under the revolving bank credit facility bear interest at a rate equal to the London Interbank Offered Rate (LIBOR) plus a spread that varies depending on the Company’s credit ratings. As of June 30, 2015 , approximately $438 million in letters of credit were outstanding under this credit facility, including the letter of credit required by the Report and Order (see Note 12. Commitments and Contingencies) . As a result of the outstanding letters of credit, which directly reduce the availability of borrowings, the Company had $2.9 billion of borrowing capacity available under the revolving bank credit facility as of June 30, 2015 . The required ratio (Leverage Ratio) of total indebtedness to trailing four quarters earnings before interest, taxes, depreciation and amortization and other non-recurring items, as defined by the credit facility (adjusted EBITDA), is not to exceed 6.5 to 1.0 through the quarter ended December 31, 2015, 6.25 to 1.0 through the quarter ended December 31, 2016 and 6.0 to 1.0 each fiscal quarter ending thereafter through expiration of the facility. The facility allows us to reduce our total indebtedness for purposes of calculating the Leverage Ratio by subtracting from total indebtedness the amount of any cash contributed into a segregated reserve account, provided that, after such cash contribution, our cash remaining on hand for operations exceeds $2.0 billion . Upon transfer, the cash contribution will remain restricted until and to the extent it is no longer required for the Leverage Ratio to remain in compliance. EDC agreement The unsecured EDC agreement provides for covenant terms similar to those of the revolving bank credit facility. As of June 30, 2015 , the EDC agreement was fully drawn totaling $800 million . Under the terms of the EDC agreement, repayments of outstanding amounts cannot be re-drawn. Secured equipment credit facilities Eksportkreditnamnden (EKN) The EKN secured equipment credit facility provides for covenant terms similar to those of the revolving bank credit facility. In 2013, we had fully drawn and began to repay the EKN secured equipment credit facility totaling $1.0 billion , which was used to finance certain network-related purchases from Ericsson. The balance outstanding at June 30, 2015 was $508 million . Finnvera plc (Finnvera) The Finnvera secured equipment credit facility provides us with the ability to borrow up to $800 million to finance network equipment-related purchases from Nokia. The facility can be divided in up to three consecutive tranches of varying size, with borrowings available through October 2017, contingent upon the amount of equipment-related purchases made by Sprint. During the three-month period ended June 30, 2015 we drew $185 million on the facility resulting in a total principal amount of $229 million outstanding. K-sure secured equipment credit facility The K-sure equipment credit facility provides for the ability to borrow up to $750 million to finance network equipment-related purchases from Samsung. The facility can be divided in up to three consecutive tranches of varying size with borrowings available until May 2018, contingent upon the amount of equipment-related purchases made by Sprint. During the three-month period ended June 30, 2015 we drew $161 million on the facility, resulting in a total principal amount of $219 million outstanding. Delcredere | Ducroire (D/D) secured equipment credit facility The D/D secured equipment credit facility provides for the ability to borrow up to $250 million to finance network equipment-related purchases from Alcatel-Lucent. As of June 30, 2015 , we had not made any draws on the facility. Borrowings under the EKN, Finnvera, K-sure and D/D secured equipment credit facilities are each secured by liens on the respective equipment purchased pursuant to each of the facilities and repayments of outstanding amounts cannot be redrawn. Each of these facilities is fully and unconditionally guaranteed by both Sprint Communications, Inc. and Sprint Corporation. The covenants under each of the four secured equipment credit facilities are similar to one another and to the covenants of our revolving bank credit facility and EDC agreement. Financing, Capital Lease and Other Obligations We have approximately 3,000 cell sites that we sold and subsequently leased back. Terms extend through 2021, with renewal options for an additional 20 years. These cell sites continue to be reported as part of our property, plant and equipment due to our continued involvement with the property sold and the transaction is accounted for as a financing. Our capital lease and other obligations are primarily related to wireless network equipment and inventory. Covenants Certain indentures and other agreements require compliance with various covenants, including covenants that limit the ability of the Company and its subsidiaries to sell all or substantially all of its assets, limit the ability of the Company and its subsidiaries to incur indebtedness and liens, and require that we maintain certain financial ratios, each as defined by the terms of the indentures, supplemental indentures and financing arrangements. As of June 30, 2015 , the Company was in compliance with all restrictive and financial covenants associated with its borrowings. A default under any of our borrowings could trigger defaults under certain of our other debt obligations, which in turn could result in the maturities being accelerated. Under our revolving bank credit facility and certain other agreements, we are currently restricted from paying cash dividends because our ratio of total indebtedness to adjusted EBITDA (each as defined in the applicable agreements) exceeds 2.5 to 1.0 .

Restructuring and Related Activities [Abstract]
Severance and Exit Costs	Note 10. Severance and Exit Costs Severance and exit costs consist of lease exit costs primarily associated with tower and cell sites, access exit costs related to payments that will continue to be made under our backhaul access contracts for which we will no longer be receiving any economic benefit, and severance costs associated with reduction in our work force. As a result of the United States Cellular (U.S. Cellular) asset acquisition, which closed in May 2013, we recorded a liability related to network shut-down costs, which primarily consisted of lease exit costs, for which we agreed to reimburse U.S. Cellular. During the quarter ended June 30, 2015 , we revised our estimate and, as a result, we reduced the reserve, resulting in approximately $20 million of income included in "Other, net" on the consolidated statements of comprehensive (loss) income. We expect to incur additional exit costs in the future related to the transition of our existing backhaul architecture to a replacement technology for our network and the efforts associated with the integration of our acquisitions, such as further evaluation of the future use of the Clearwire 4G broadband network, among other initiatives. These additional exit costs are expected to range between approximately $75 million to $150 million , of which the majority is expected to be incurred by March 31, 2016. The following provides the activity in the severance and exit costs liability included in "Accounts payable," "Accrued expenses and other current liabilities" and "Other liabilities" within the consolidated balance sheets: March 31, Net (Benefit) Expense Cash Payments and Other June 30, (in millions) Lease exit costs $ 291 $ (15 ) (1) $ (35 ) $ 241 Severance costs 119 7 (2) (56 ) 70 Access exit costs 44 1 (3) (18 ) 27 $ 454 $ (7 ) $ (109 ) $ 338 _________________ (1) In addition to the $20 million income (Wireless only) related to U.S. Cellular, we recognized costs of $5 million (Wireless only) for the three-month period ended June 30, 2015 included in "Other, net" on the consolidated statements of comprehensive (loss) income. (2) For the three-month period ended June 30, 2015 , we recognized costs of $7 million ( $6 million Wireless, $1 million Wireline) included in "Other, net" on the consolidated statements of comprehensive (loss) income. (3) For the three-month period ended June 30, 2015 , we recognized costs of $1 million (Wireless only) included in "Other, net" on the consolidated statements of comprehensive (loss) income.

Income Tax Disclosure [Abstract]
Income Taxes	Note 11. Income Taxes The differences that caused our effective income tax rates to vary from the 35% U.S. federal statutory rate for income taxes were as follows: Three Months Ended 2015 2014 (in millions) Income tax benefit (expense) at the federal statutory rate $ 13 $ (3 ) Effect of: State income taxes, net of federal income tax effect (1 ) (7 ) State law changes, net of federal income tax effect 21 — Change in federal and state valuation allowance (22 ) 27 Other, net 6 (2 ) Income tax benefit $ 17 $ 15 Effective income tax rate 45.9 % (187.5 )% The realization of deferred tax assets, including net operating loss carryforwards, is dependent on the generation of future taxable income sufficient to realize the tax deductions, carryforwards and credits. However, our history of annual losses reduces our ability to rely on expectations of future income in evaluating the ability to realize our deferred tax assets. Valuation allowances on deferred tax assets are recognized if it is determined that it is more likely than not that the asset will not be realized. As a result, the Company recognized income tax expense to increase the valuation allowance of $22 million during the three-month period ended June 30, 2015 on deferred tax assets primarily related to losses incurred during the period that were not currently realizable and expenses recorded during the period that were not currently deductible for income tax purposes. The Company recognized income tax benefit to decrease the valuation allowance of $27 million during the three-month period ended June 30, 2014 . This net decrease in the valuation allowance resulted from a decrease of $73 million related to the planned disposition of certain FCC licenses, offset by a $46 million increase in the valuation allowance primarily attributable to the net increase in deferred tax assets related to the federal and state net operating loss carryforwards generated during the period. We do not expect to record significant tax benefits on future net operating losses until our circumstances justify the recognition of such benefits. We believe it is more likely than not that our remaining deferred income tax assets, net of the valuation allowance, will be realized based on current income tax laws and expectations of future taxable income stemming from the reversal of existing deferred tax liabilities. Uncertainties surrounding income tax law changes, shifts in operations between state taxing jurisdictions and future operating income levels may, however, affect the ultimate realization of all or some of these deferred income tax assets. Income tax benefit of $17 million for the three-month period ended June 30, 2015 is primarily attributable to tax benefits recorded as a result of changes in state income tax laws. Income tax benefit of $15 million for the three-month period ended June 30, 2014 is primarily attributable to tax benefits related to the planned disposition of certain FCC licenses. The net income tax benefits in both periods were partially offset by tax expense on taxable temporary differences from the tax amortization of FCC licenses during the period. FCC licenses are amortized over 15 years for income tax purposes but, because these licenses have an indefinite life, they are not amortized for financial statement reporting purposes. These temporary differences result in net deferred income tax expense since they cannot be scheduled to reverse during the loss carryforward period. As of June 30, 2015 and March 31, 2015 , we maintained unrecognized tax benefits of $168 million and $163 million , respectively. Cash paid for income taxes, net, was $26 million and $28 million for the three-month periods ended June 30, 2015 and 2014 , respectively.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 12. Commitments and Contingencies Litigation, Claims and Assessments In March 2009, a stockholder brought suit, Bennett v. Sprint Nextel Corp. , in the U.S. District Court for the District of Kansas, alleging that Sprint Communications and three of its former officers violated Section 10(b) of the Exchange Act and Rule 10b-5 by failing adequately to disclose certain alleged operational difficulties subsequent to the Sprint-Nextel merger, and by purportedly issuing false and misleading statements regarding the write-down of goodwill. The plaintiff sought class action status for purchasers of Sprint Communications common stock from October 26, 2006 to February 27, 2008. On January 6, 2011, the Court denied the motion to dismiss. Subsequently, our motion to certify the January 6, 2011 order for an interlocutory appeal was denied. On March 27, 2014, the court certified a class including bondholders as well as stockholders. On April 11, 2014, we filed a petition to appeal that certification order to the Tenth Circuit Court of Appeals. The petition was denied on May 23, 2014. After mediation, the parties have reached an agreement in principle to settle the matter, and the settlement amount is expected to be substantially paid by the Company's insurers. The district court granted preliminary approval of the proposed settlement on April 10, 2015 and a final approval hearing has been scheduled for August 5, 2015. We do not expect the resolution of this matter to have a material adverse effect on our financial position or results of operations. In addition, five related stockholder derivative suits were filed against Sprint Communications and certain of its present and/or former officers and directors. The first, Murphy v. Forsee , was filed in state court in Kansas on April 8, 2009, was removed to federal court, and was stayed by the court pending resolution of the motion to dismiss the Bennett case; the second, Randolph v. Forsee , was filed on July 15, 2010 in state court in Kansas, was removed to federal court, and was remanded back to state court; the third, Ross-Williams v. Bennett, et al. , was filed in state court in Kansas on February 1, 2011; the fourth, Price v. Forsee, et al., was filed in state court in Kansas on April 15, 2011; and the fifth, Hartleib v. Forsee, et. al ., was filed in federal court in Kansas on July 14, 2011. These cases are essentially stayed while the Bennett case is pending. We do not expect the resolution of these matters to have a material adverse effect on our financial position or results of operations. On April 19, 2012, the New York Attorney General filed a complaint alleging that Sprint Communications has fraudulently failed to collect and pay more than $100 million in New York sales taxes on receipts from its sale of wireless telephone services since July 2005. The complaint seeks recovery of triple damages as well as penalties and interest. Sprint Communications moved to dismiss the complaint on June 14, 2012. On July 1, 2013, the court entered an order denying the motion to dismiss in large part, although it did dismiss certain counts or parts of certain counts. Sprint Communications has appealed that order and the intermediate appellate court affirmed the order of the trial court. Our petition for leave to bring an interlocutory appeal to the highest court in New York was granted and briefing of that appeal was completed in January 2015. We believe the complaint is without merit and intend to continue to defend this matter vigorously. We do not expect the resolution of this matter to have a material adverse effect on our financial position or results of operations. Eight related stockholder derivative suits have been filed against Sprint Communications and certain of its current and former officers and directors. Each suit alleges generally that the individual defendants breached their fiduciary duties to Sprint Communications and its stockholders by allegedly permitting, and failing to disclose, the actions alleged in the suit filed by the New York Attorney General. One suit, filed by the Louisiana Municipal Police Employees Retirement System, was dismissed by a federal court. Two suits were filed in state court in Johnson County, Kansas and one of those suits was dismissed as premature; and five suits are pending in federal court in Kansas. The remaining Kansas suits have been stayed. We do not expect the resolution of these matters to have a material adverse effect on our financial position or results of operations. Sprint Communications, Inc. is also a defendant in a complaint filed by stockholders of Clearwire Corporation asserting claims for breach of fiduciary duty by Sprint Communications, and related claims and otherwise challenging the Clearwire Acquisition. ACP Master, LTD, et al. v. Sprint Nextel Corp., et al. , was filed April 26, 2013, in Chancery Court in Delaware. Our motion to dismiss the suit was denied, and discovery has begun. Plaintiffs in the ACP Master, LTD suit have also filed suit requesting an appraisal of the fair value of their Clearwire stock, and discovery is proceeding in that case. Sprint Communications intends to defend the ACP Master, LTD case vigorously. We do not expect the resolution of this matter to have a material adverse effect on our financial position or results of operations. Sprint is currently involved in numerous court actions alleging that Sprint is infringing various patents. Most of these cases effectively seek only monetary damages. A small number of these cases are brought by companies that sell products and seek injunctive relief as well. These cases have progressed to various degrees and a small number may go to trial if they are not otherwise resolved. Adverse resolution of these cases could require us to pay significant damages, cease certain activities, or cease selling the relevant products and services. In many circumstances, we would be indemnified for monetary losses that we incur with respect to the actions of our suppliers or service providers. We do not expect the resolution of these cases to have a material adverse effect on our financial position or results of operations. In October 2013, the FCC Enforcement Bureau began to issue notices of apparent liability (NALs) to other Lifeline providers, imposing fines for intracarrier duplicate accounts identified by the government during its audit function. Those audits also identified a small percentage of potentially duplicative intracarrier accounts related to our Assurance Wireless business. No NAL has yet been issued with respect to Sprint and we do not know if one will be issued. Further, we are not able to reasonably estimate the amount of any claim for penalties that might be asserted. However, based on the information currently available, if a claim is asserted by the FCC, Sprint does not believe that any amount ultimately paid would be material to the Company’s results of operations or financial position. Beginning in early 2012, a group of state attorneys general began an investigation into the practice of wireless carriers including on their bills charges for certain content from third party providers, particularly premium short message services, and the measures taken by carriers to ensure that such charges were appropriately authorized. Late in 2013, the Consumer Financial Protection Bureau (CFPB) also began a separate investigation into the issue, and the FCC began its own investigation in mid-2014. In July 2014, the Federal Trade Commission (FTC) brought suit against T-Mobile, alleging that it included unauthorized charges on its bills; in December 2014, T-Mobile entered into a settlement agreement with the FTC, FCC and state attorneys general. In October 2014, the FTC, FCC and states announced a settlement with AT&T regarding third-party billing issues. In December, 2014, the CFPB brought suit against Sprint regarding third-party billing issues. On May 6, 2015, we entered into agreements with the FCC, CFPB, and various states to settle all issues involved in the investigation for an aggregate amount that is not material to the Company’s results of operations or financial position. Various other suits, inquiries, proceedings and claims, either asserted or unasserted, including purported class actions typical for a large business enterprise and intellectual property matters, are possible or pending against us or our subsidiaries. If our interpretation of certain laws or regulations, including those related to various federal or state matters such as sales, use or property taxes, or other charges were found to be mistaken, it could result in payments by us. While it is not possible to determine the ultimate disposition of each of these proceedings and whether they will be resolved consistent with our beliefs, we expect that the outcome of such proceedings, individually or in the aggregate, will not have a material adverse effect on our financial position or results of operations. Spectrum Reconfiguration Obligations In 2004, the FCC adopted a Report and Order that included new rules regarding interference in the 800 MHz band and a comprehensive plan to reconfigure the 800 MHz band. The Report and Order provides for the exchange of a portion of our 800 MHz FCC spectrum licenses, and requires us to fund the cost incurred by public safety systems and other incumbent licensees to reconfigure the 800 MHz spectrum band. Also, in exchange, we received licenses for 10 MHz of nationwide spectrum in the 1.9 GHz band. The minimum cash obligation is $2.8 billion under the Report and Order. We are, however, obligated to pay the full amount of the costs relating to the reconfiguration plan, even if those costs exceed $2.8 billion . As required under the terms of the Report and Order, a letter of credit has been secured to provide assurance that funds will be available to pay the relocation costs of the incumbent users of the 800 MHz spectrum. The letter of credit was initially $2.5 billion , but has been reduced during the course of the proceeding to $376 million as of June 30, 2015 . Since the inception of the program, we have incurred payments of approximately $3.4 billion directly attributable to our performance under the Report and Order, including approximately $25 million during the three-month period ended June 30, 2015 . When incurred, substantially all costs are accounted for as additions to FCC licenses with the remainder as property, plant and equipment. Although costs incurred through June 30, 2015 have exceeded $2.8 billion , not all of those costs have been reviewed and accepted as eligible by the transition administrator. During the three-month period ended June 30, 2014, we received a cash payment of approximately $95 million , which represented a reimbursement of prior reconfiguration costs incurred by us that also benefited spectrum recently auctioned by the FCC. We do not expect any further reimbursements. Completion of the 800 MHz band reconfiguration was initially required by June 26, 2008 and public safety reconfiguration is nearly complete across the country with the exception of the State of Washington and Arizona, California, Texas and New Mexico. The FCC continues to grant the remaining 800 MHz public safety licensees additional time to complete their band reconfigurations which, in turn, delays our access to our 800 MHz replacement channels in these areas. In the areas where band reconfiguration is complete, Sprint has received its replacement spectrum in the 800 MHz band and Sprint is deploying 3G CDMA and 4G LTE on this spectrum in combination with its spectrum in the 1.9 GHz and 2.5 GHz bands.

Earnings Per Share [Abstract]
Per Share Data	Note 13. Per Share Data Basic net (loss) income per common share is calculated by dividing net (loss) income by the weighted average number of common shares outstanding during the period. Diluted net (loss) income per common share adjusts basic net (loss) income per common share, computed using the treasury stock method, for the effects of potentially dilutive common shares, if the effect is not antidilutive. Outstanding options and restricted stock units (exclusive of participating securities) that had no effect on our computation of dilutive weighted average number of shares outstanding as their effect would have been antidilutive were approximately 75 million as of the period ended June 30, 2015 , in addition to all 55 million shares issuable under the warrant held by SoftBank. The warrant was issued to SoftBank at the close of the merger with SoftBank and is exercisable at $5.25 per share at the option of SoftBank, in whole or in part, at any time on or prior to July 10, 2018. For the three-month period ended June 30, 2014 , the computation of diluted net (loss) income per common share includes the effect of dilutive securities consisting of approximately 36 million options and restricted stock units, in addition to 22 million shares attributable to the warrant held by SoftBank. Outstanding options to purchase shares totaling 13 million were not included in the computation of diluted net (loss) income per common share for the period ended June 30, 2014 because to do so would have been antidilutive.

Segments

Segment Reporting [Abstract]
Segment Information	Note 14. Segments Sprint operates two reportable segments: Wireless and Wireline. • Wireless primarily includes retail, wholesale, and affiliate revenue from a wide array of wireless voice and data transmission services and equipment revenue from the sale of wireless devices (handsets and tablets) and accessories in the U.S., Puerto Rico and the U.S. Virgin Islands. • Wireline primarily includes revenue from domestic and international wireline voice and data communication services provided to other communications companies and targeted business and consumer subscribers, in addition to our Wireless segment. We define segment earnings as wireless or wireline operating (loss) income before other segment expenses such as depreciation, amortization, severance, exit costs, goodwill impairments, asset impairments, and other items, if any, solely and directly attributable to the segment representing items of a non-recurring or unusual nature. Expense and income items excluded from segment earnings are managed at the corporate level. Transactions between segments are generally accounted for based on market rates, which we believe approximate fair value. The Company generally re-establishes these rates at the beginning of each fiscal year. Over the past several years, there has been an industry-wide trend of lower rates due to increased competition from other wireline and wireless communications companies as well as cable and Internet service providers. Segment financial information is as follows: Statement of Operations Information Wireless Wireline Corporate, Other and Eliminations Consolidated (in millions) Three Months Ended June 30, 2015 Net operating revenues $ 7,540 $ 483 $ 4 $ 8,027 Inter-segment revenues (1) — 147 (147 ) — Total segment operating expenses (5,466 ) (621 ) 142 (5,945 ) Segment earnings $ 2,074 $ 9 $ (1 ) 2,082 Less: Depreciation (1,241 ) Amortization (347 ) Other, net (2) 7 Operating income 501 Interest expense (542 ) Other income, net 4 Loss before income taxes $ (37 ) Statement of Operations Information Wireless Wireline Corporate, Consolidated (in millions) Three Months Ended June 30, 2014 Net operating revenues $ 8,193 $ 593 $ 3 $ 8,789 Inter-segment revenues (1) — 153 (153 ) — Total segment operating expenses (6,400 ) (711 ) 149 (6,962 ) Segment earnings $ 1,793 $ 35 $ (1 ) 1,827 Less: Depreciation (868 ) Amortization (413 ) Other, net (2) (27 ) Operating income 519 Interest expense (512 ) Other income, net 1 Income before income taxes $ 8 Other Information Wireless Wireline Corporate and Other Consolidated (in millions) Capital expenditures for the three months ended June 30, 2015 $ 1,640 $ 68 $ 94 $ 1,802 Capital expenditures for the three months ended June 30, 2014 $ 1,120 $ 59 $ 67 $ 1,246 _________________ (1) Inter-segment revenues consist primarily of wireline services provided to the Wireless segment for resale to, or use by, wireless subscribers.

Related Party Transactions [Abstract]
Related Party Transactions Disclosure [Text Block]	Note 15. Related-Party Transactions SoftBank Related-Party Transactions In addition to agreements arising out of or relating to the merger with SoftBank, Sprint has entered into various other arrangements with SoftBank or its controlled affiliates (SoftBank Parties) or with third parties to which SoftBank Parties are also parties, including for international wireless roaming, wireless and wireline call termination, real estate, device and accessory purchasing, and other services. Specifically, we have arrangements with Brightstar US, Inc. (Brightstar), a wholly-owned subsidiary of SoftBank, whereby Brightstar provides supply chain and inventory management services to us in our indirect channels and whereby Sprint may sell new and used devices and new accessories to Brightstar for its own purposes. The supply chain and inventory management arrangement contemplates that Brightstar will purchase inventory from the original equipment manufacturers (OEMs) to sell directly to our indirect dealers. As compensation for these services, we remit per unit fees to Brightstar for each device sold to dealers or retailers in our indirect channels. During the three-month period ended June 30, 2015 , we incurred fees under these arrangements totaling $33 million . Until Brightstar successfully negotiates contracts with, and procures credit from, our existing OEMs, Brightstar will purchase device and accessory inventory from us in order to fulfill orders within our indirect channel. We have provided a $1.0 billion credit line to Brightstar to facilitate certain of these arrangements. As a result, we shifted our concentration of credit risk away from our indirect channel partners to Brightstar. As Brightstar is a wholly-owned subsidiary of SoftBank, we expect SoftBank will provide the necessary support to ensure that Brightstar will fulfill its obligations to us under these agreements. However, we have no assurance that SoftBank will provide such support. We may also purchase new and used devices and accessories from Brightstar to be sold in our direct channels or used to fulfill service and repair needs. Amounts included in our consolidated financial statements associated with these arrangements with Brightstar were as follows: Consolidated balance sheets: June 30, March 31, (in millions) Accounts receivable $ 156 $ 430 Accounts payable $ 114 $ 96 Consolidated statements of comprehensive (loss) income: Three Months Ended June 30, 2015 2014 (in millions) Equipment revenues $ 375 $ 17 Cost of products $ 418 $ 16 Additionally, we had arrangements with a wholly-owned subsidiary of Brightstar (Brightstar Subsidiary) to procure devices and accessories on our behalf with certain third-party vendors under existing purchase arrangements Sprint has with those vendors as well as new vendor purchase arrangements entered into by the Brightstar Subsidiary. The procurement services include placing orders, processing invoices, receiving payments from us and making payments to our suppliers on our behalf. In mid-December 2014, we decided to terminate the agreement under which the Brightstar Subsidiary would procure devices on our behalf. As the Brightstar Subsidiary is now only purchasing accessories on our behalf, the volume and dollar amount of transactions has significantly declined. The amounts in our consolidated financial statements related to these transactions for the current period are not material, and we do not expect these amounts to be material in any future periods. All other transactions under agreements with SoftBank Parties, in the aggregate, were immaterial through the period ended June 30, 2015.

Condensed Financial Information of Parent Company Only Disclosure [Abstract]
Condensed Financial Statements [Text Block]	Note 16. Guarantor Financial Information On September 11, 2013, Sprint Corporation issued $2.25 billion aggregate principal amount of 7.250% notes due 2021 and $4.25 billion aggregate principal amount of 7.875% notes due 2023 in a private placement transaction with registration rights. On December 12, 2013, Sprint Corporation issued $2.5 billion aggregate principal amount of 7.125% notes due 2024 in a private placement transaction with registration rights. Each of these issuances is fully and unconditionally guaranteed by Sprint Communications, Inc. (Subsidiary Guarantor), which is a 100 percent owned subsidiary of Sprint Corporation (Parent/Issuer). In connection with the foregoing, the registration rights agreements with respect to the notes required the Company and Sprint Communications, Inc. to use their reasonable best efforts to cause an offer to exchange the notes for a new issue of substantially identical exchange notes registered under the Securities Act of 1933. Accordingly, in November 2014, we completed an exchange offer for these notes in compliance with our registration obligations. We did not receive any proceeds from this exchange offer. In addition, on February 24, 2015, Sprint Corporation issued $1.5 billion aggregate principal amount of 7.625% notes due 2025, which are fully and unconditionally guaranteed by Sprint Communications, Inc. Under the Subsidiary Guarantor's revolving bank credit facility and certain other agreements, the Subsidiary Guarantor is currently restricted from paying cash dividends to the Parent/Issuer or any Non-Guarantor Subsidiary because the ratio of total indebtedness to adjusted EBITDA (each as defined in the applicable agreement) exceeds 2.5 to 1.0 . In May 2014, certain wholly-owned subsidiaries of Sprint entered into a Receivables Facility arrangement to sell certain accounts receivable on a revolving basis, subject to a maximum funding limit. The Receivables Facility was amended in April 2015, which, among other things, extended the expiration date to March 31, 2017 and increased the maximum funding limit to $3.3 billion . In connection with this arrangement, Sprint formed certain wholly-owned subsidiaries, which are bankruptcy remote SPEs and are included in the Non-Guarantor Subsidiaries condensed consolidated financial information (see Note 3. Accounts Receivable Facility) . We have accounted for investments in subsidiaries using the equity method. Presented below is the condensed consolidating financial information.
