Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Note 1 – Basis of Presentation The unaudited condensed consolidated financial statements of T-Mobile US, Inc. (“T-Mobile” or the “Company”) include all adjustments of a normal recurring nature necessary for the fair presentation of the results for the interim periods presented. The results for the interim periods are not necessarily indicative of those for the full year. The condensed consolidated financial statements should be read in conjunction with the Company’s consolidated financial statements included in the Annual Report on Form 10-K for the year ended December 31, 2014 . Certain prior period amounts have been reclassified to conform to the current presentation. The condensed consolidated financial statements include the balances and results of operations of T-Mobile and its consolidated subsidiaries. T-Mobile consolidates all majority-owned subsidiaries over which it exercises control, as well as variable interest entities (“VIE”) where it is deemed to be the primary beneficiary and VIEs which cannot be deconsolidated. Intercompany transactions and balances have been eliminated in consolidation. The preparation of financial statements in conformity with United States (“U.S.”) generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions which affect the financial statements and accompanying notes. Estimates are based on historical experience, where applicable, and other assumptions which management believes are reasonable under the circumstances. These estimates are inherently subject to judgment and actual results could differ from those estimates. Recently-Issued Accounting Standards In April 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2015-03, “Simplifying the Presentation of Debt Issuance Costs.” The standard requires 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 recognition and measurement guidance for debt issuance costs are not affected. The standard will become effective for T-Mobile beginning January 1, 2016. The implementation of this standard is not expected to have a significant impact on T-Mobile’s consolidated financial statements. In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers.” The standard requires entities to recognize revenue through the application of a five-step model, which includes identification of the contract, identification of the performance obligations, determination of the transaction price, allocation of the transaction price to the performance obligations, and recognition of revenue as the entity satisfies the performance obligations. In July 2015, the FASB voted to defer the effective date by one year to periods beginning January 1, 2018; however, early adoption with the original effective date for periods beginning January 1, 2017 will be permitted. The Company is currently evaluating the guidance to determine the potential impact on T-Mobile’s consolidated financial statements.

Quarterly Financial Information Disclosure [Abstract]
Significant Transactions	Note 2 – Significant Transactions Spectrum License Transactions In 2014 , the Federal Communications Commission (“FCC”) began conducting an auction of Advanced Wireless Service (“AWS”) spectrum licenses. In January 2015 , the FCC announced T-Mobile was the winning bidder of AWS spectrum licenses covering approximately 97 million people for an aggregate bid price of $1.8 billion . T-Mobile paid the FCC $1.4 billion for the AWS spectrum licenses in the first quarter of 2015 , which was in addition to a deposit of $0.4 billion provided to the FCC in 2014 . In the second quarter of 2015 , T-Mobile received the AWS spectrum licenses. Debt The interest rates on the senior reset notes to affiliates are adjusted at the reset dates to rates defined in the applicable supplemental indenture. In April 2015 , the interest rate on the $1.3 billion of senior reset notes to affiliates due 2019 was adjusted from 5.578% to 6.288% and the interest rate on the $1.3 billion of senior reset notes to affiliates due 2020 was adjusted from 5.656% to 6.366% .

Receivables [Abstract]
Equipment Installment Plan Receivables	Note 3 – Equipment Installment Plan Receivables T-Mobile offers certain retail customers the option to pay for their devices and other purchases in installments over a period of up to 24 months using an Equipment Installment Plan (“EIP”). The following table summarizes the EIP receivables: (in millions) June 30, December 31, EIP receivables, gross $ 5,555 $ 5,138 Unamortized imputed discount (329 ) (332 ) EIP receivables, net of unamortized imputed discount 5,226 4,806 Allowance for credit losses (112 ) (116 ) EIP receivables, net $ 5,114 $ 4,690 Classified on the balance sheet as: Equipment installment plan receivables, net $ 3,503 $ 3,062 Equipment installment plan receivables due after one year, net 1,611 1,628 EIP receivables, net $ 5,114 $ 4,690 T-Mobile uses a proprietary credit scoring model that measures the credit quality of a customer at the time of application for mobile communications service using several factors, such as credit bureau information, consumer credit risk scores and service plan characteristics. Based upon customer credit profiles, T-Mobile classifies EIP receivables into the credit categories of “Prime” and “Subprime”. Prime customer receivables are those with lower delinquency risk and Subprime customer receivables are those with higher delinquency risk. Subprime customers are generally required to make a down payment on their equipment purchases. In addition, certain customers within the Subprime category are required to pay an advance deposit. EIP receivables for which invoices have not yet been generated for the customer are classified as Unbilled. EIP receivables for which invoices have been generated but which are not past the contractual due date are classified as Billed – Current. EIP receivables for which invoices have been generated and the payment is past the contractual due date are classified as Billed – Past Due. The balance and aging of the EIP receivables on a gross basis by credit category were as follows: June 30, 2015 December 31, 2014 (in millions) Prime Subprime Total Prime Subprime Total Unbilled $ 2,742 $ 2,491 $ 5,233 $ 2,639 $ 2,213 $ 4,852 Billed – Current 110 105 215 104 95 199 Billed – Past Due 42 65 107 35 52 87 EIP receivables, gross $ 2,894 $ 2,661 $ 5,555 $ 2,778 $ 2,360 $ 5,138 Activity in the unamortized imputed discount and allowance for credit losses balances for the EIP receivables was as follows: (in millions) June 30, Imputed discount and allowance for credit losses, beginning of period $ 448 Bad debt expense 155 Write-offs, net of recoveries (159 ) Change in imputed discount on short-term and long-term EIP receivables (3 ) Imputed discount and allowance for credit losses, end of period $ 441 Imputed discount and allowance for credit losses includes the long-term portion of imputed discount of $ 57 million and $ 61 million as of June 30, 2015 and December 31, 2014 , respectively. The EIP receivables had weighted average effective imputed interest rates of 9.1% and 9.7% as of June 30, 2015 and December 31, 2014 , respectively.

Factoring Arrangement

Factoring Arrangement	6 Months Ended

Transfers and Servicing [Abstract]
Factoring Arrangement	Note 4 – Factoring Arrangement Transaction Overview In 2014, T-Mobile entered into a two-year factoring arrangement to sell certain service accounts receivable on a revolving basis with a current maximum funding limit of $640 million , subject to change upon notification to certain third parties. Sales of receivables occur daily and are settled on a monthly basis. The receivables consist of service charges currently due from customers and are short-term in nature. In connection with the factoring arrangement, the Company formed a wholly-owned subsidiary, which qualifies as a bankruptcy remote special purpose entity (“Factoring SPE”). Pursuant to the factoring arrangement, certain subsidiaries of T-Mobile transfer selected receivables to the Factoring SPE. The Factoring SPE then sells the receivables to an unaffiliated entity (“Factoring VIE”), which was established to facilitate the sale of ownership interest in the receivables to certain third parties. Variable Interest Entity The Company determined the Factoring VIE is a VIE as it lacks sufficient equity to finance its activities. The Company has a variable interest in the Factoring VIE, but is not the primary beneficiary as it lacks the power to direct the activities that most significantly impact the Factoring VIE’s economic performance. The activities which most significantly impact the Factoring VIE’s economic performance include committing the Factoring VIE to legal agreements to purchase or sell assets, selecting which receivables are purchased in the factoring arrangement, determining whether the Factoring VIE will sell interests in the purchased service receivables to other parties, and servicing of the receivables. While T-Mobile acts as the servicer of the sold receivables, which is considered a significant activity of the VIE, the Company is acting as an agent in its capacity as the servicer and the counterparty to the factoring arrangement has the ability to remove T-Mobile as the servicing agent of the receivables at will with no recourse available to T-Mobile. As the Company has determined it is not the primary beneficiary and does not hold any equity interest, the results of the Factoring VIE are not consolidated into the Company’s condensed consolidated financial statements. Sales of Receivables The sales of receivables through the factoring arrangement are treated as sales of financial assets. Upon sale, T-Mobile derecognizes the receivables, as well as the related allowances, and recognizes the net proceeds in cash provided by operating activities. The proceeds were net of a receivable for the remainder of the purchase price (“deferred purchase price”), which is received from collections on the service receivables. T-Mobile recognizes the deferred purchase price in cash provided by operating activities due to the short duration of the receivables sold and the nature of the related activity. The deferred purchase price represents a financial asset that can be settled in such a way that T-Mobile may not recover substantially all of its recorded investment due to the creditworthiness of customers. As a result, T-Mobile elected at inception to classify the deferred purchase price as a trading security carried at fair value with unrealized gains and losses from changes in fair value included in selling, general and administrative expense. The fair value of the deferred purchase price was determined based on a discounted cash flow model which uses unobservable inputs (Level 3 inputs), including customer default rates. Due to the short-term nature of the underlying financial assets, the carrying value approximated fair value. Other current assets, which primarily consisted of the deferred purchase price, accounts payable and accrued liabilities, and other current liabilities related to the factoring arrangement were held by the Factoring SPE. The following table summarizes the impacts to the condensed consolidated balance sheets: (in millions) June 30, December 31, Derecognized net receivables $ 795 $ 768 Net cash proceeds since inception 599 610 Other current assets 220 204 Accounts payable and accrued liabilities 18 13 Other current liabilities 64 55 Net expenses resulting from the sales of receivables are recognized in selling, general and administrative expense. Prior to the sales of receivables, T-Mobile recognizes impairment charges, rather than bad debt expense, to reduce the receivables to fair value for estimated losses resulting from uncollectible balances. Net expenses also include any resulting gains or losses from the sales of receivables, unrealized gains and losses related to the deferred purchase price, and factoring fees. For the three months ended June 30, 2015 and 2014 , T-Mobile recognized net expenses of $48 million and $59 million , respectively. For the six months ended June 30, 2015 and 2014 , T-Mobile recognized net expenses of $113 million and $86 million , respectively. Continuing Involvement T-Mobile has continuing involvement with the sold receivables as it services the receivables and is required to repurchase certain receivables, including aged receivables and receivables where write-off is imminent, pursuant to the factoring arrangement. T-Mobile will continue to service the customer and their related receivables, including facilitating customer payment collection, in exchange for a monthly servicing fee. As the receivables are sold on a revolving basis, the customer payment collections are reinvested in new receivable sales. While servicing the receivables, the same policies and procedures are applied to the sold receivables that apply to owned receivables and T-Mobile continues to maintain normal relationships with its customers. In addition, T-Mobile has continuing involvement related to the sold receivables as it may be responsible for absorbing additional credit losses pursuant to the agreement. The Company’s maximum exposure to loss related to the involvement with the Factoring VIE was $499 million as of June 30, 2015 . The maximum exposure to loss, which is required disclosure under GAAP, represents an estimated loss that would be incurred under severe, hypothetical circumstances whereby the Company would not receive the portion of the contractual proceeds withheld by the Factoring VIE and would also be required to repurchase the maximum amount of receivables pursuant to the agreement without consideration for any recovery. As T-Mobile believes the probability of these circumstances occurring is very remote, the maximum exposure to loss is not an indication of the Company’s expected loss.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 5 – Fair Value Measurements Long-term Debt The fair value of the Company’s long-term debt to third parties was determined based on quoted market prices in active markets, and therefore was classified as Level 1 in the fair value hierarchy. The fair value of the Company’s long-term debt to affiliates was determined based on a discounted cash flow approach which considers the future cash flows discounted at current rates. The approach includes an estimate for the stand-alone credit risk of T-Mobile. The Company’s long-term debt to affiliates was classified as Level 2 in the fair value hierarchy. The carrying amounts and fair values of the Company’s long-term debt were as follows: June 30, 2015 December 31, 2014 (in millions) Carrying Amount Fair Value Carrying Amount Fair Value Long-term debt to third parties principal, excluding capital leases $ 15,600 $ 16,266 $ 15,600 $ 16,034 Long-term debt to affiliates 5,600 6,013 5,600 5,780 Although the Company has determined the estimated fair value using available market information and commonly accepted valuation methodologies, considerable judgment was required in interpreting market data to develop fair value estimates for the long-term debt. The fair value estimates were based on information available as of June 30, 2015 and December 31, 2014 . As such, the Company’s estimates are not necessarily indicative of the amount the Company could realize in a current market exchange.

Potentially dilutive outstanding stock options were 1 million and 2 million as of June 30, 2015 and 2014 , respectively. Potentially dilutive unvested stock awards were not significant as of June 30, 2015 and 2014 , respectively. Unvested performance stock units were based on the number of shares ultimately expected to vest based on T-Mobile’s business performance against the specified performance goal. Potentially dilutive common stock equivalents related to the mandatory convertible preferred stock were 32 million as of June 30, 2015 . There was no mandatory convertible preferred stock outstanding as of June 30, 2014 .

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 7 – Commitments and Contingencies Commitments Guarantee Liabilities T-Mobile offers a device trade-in program, Just Upgrade My Phone (“JUMP!”), which provides eligible customers a specified-price trade-in right to upgrade their device. For customers who enroll in the device trade-in program, the Company defers the portion of equipment revenues which represents the estimated value of the specified-price trade-in right guarantee. When customers upgrade their devices, the difference between the trade-in credit to the customer and the fair value of the returned devices is recorded against the guarantee liabilities. Guarantee liabilities included in other current liabilities were $ 265 million and $ 286 million as of June 30, 2015 and December 31, 2014 , respectively. The estimated EIP receivable balance if all enrolled handset upgrade program customers were to claim their benefit, not including any trade-in value of the required used handset, was $ 3.0 billion as of June 30, 2015 . This is not an indication of the Company’s expected loss exposure as it does not consider the expected fair value of the used handset, which is required to be in good working condition at trade-in, nor does it consider the probability and timing of trade-in. Contingencies and Litigation T-Mobile is involved in various lawsuits, claims, investigations and proceedings that arise in the ordinary course of business, which include numerous court actions alleging that T-Mobile is infringing various patents. Virtually all of the patent infringement cases are brought by non-practicing entities and effectively seek only monetary damages, although they occasionally seek injunctive relief as well. The matters described above have progressed to various stages and a small number may go to trial in the coming 12 months if they are not otherwise resolved. T-Mobile has established an accrual with respect to certain of these matters, where appropriate, which is reflected in the condensed consolidated financial statements but that T-Mobile does not consider, individually or in the aggregate, material. An accrual is established when T-Mobile believes it is both probable that a loss has been incurred and an amount can be reasonably estimated. For other matters, where the Company has not determined that a loss is probable or because the amount of loss cannot be reasonably estimated, the Company has not recorded an accrual due to various factors typical in contested proceedings, including but not limited to: uncertainty concerning legal theories and their resolution by courts or regulators; uncertain damage theories and demands; and a less than fully developed factual record. While T-Mobile does not expect that the ultimate resolution of these proceedings, individually or in the aggregate will have a material adverse effect on the Company’s financial position, an unfavorable outcome of some or all of these proceedings could have a material adverse impact on results of operations or cash flows for a particular period. This assessment is based on T-Mobile’s current understanding of relevant facts and circumstances. As such, T-Mobile’s view of these matters is subject to inherent uncertainties and may change in the future.

Supplemental Financial Statement Elements [Abstract]
Additional Financial Information	Note 8 – Additional Financial Information Network Decommissioning Costs Prior to the closing of the business combination with MetroPCS Communications, Inc. (“MetroPCS”), T-Mobile developed integration plans which included the decommissioning of the MetroPCS Code Division Multiple Access (“CDMA”) network and certain other redundant network cell sites. In 2014, T-Mobile began decommissioning the MetroPCS CDMA network and redundant network cell sites. Network decommissioning costs primarily relate to the acceleration of lease costs for decommissioned cell sites for which T-Mobile has ceased use and will no longer receive any economic benefit. Accrued liabilities for network decommissioning costs will be relieved as cash payments are made over the remaining lease terms through 2028. In addition, network decommissioning costs include the write off of certain items related to certain cell sites, which consist of prepaid rent expense, favorable leases, construction in progress, unfavorable leases and deferred rent expense. For the three and six months ended June 30, 2015 , T-Mobile recognized network decommissioning costs, including effects of certain items, of $34 million and $162 million , respectively. T-Mobile intends to decommission certain cell sites and incur additional network decommissioning costs in the range of $350 million to $450 million , with substantially all the costs expected to be recognized through the rest of 2015. Activities in liabilities for network decommissioning costs were as follows: (in millions) June 30, Balances, beginning of period $ 239 Network decommissioning costs, excluding effects of certain items 153 Cash payments (78 ) Balances, end of period $ 314 Classified on the balance sheet as: Accounts payable and accrued liabilities $ 90 Other long-term liabilities 224 Network decommissioning liabilities $ 314 In addition, for the six months ended June 30, 2015 , T-Mobile settled asset retirement obligations of $66 million , in connection with the decommissioning of certain cell sites. Income Taxes Income tax expense was $2 million and $286 million for the three months ended June 30, 2015 and 2014, respectively. Income tax benefit was $39 million for the six months ended June 30, 2015 and income tax expense was $184 million for the six months ended June 30, 2014. The effective income tax rate was 0.6% and 42.2% for the three months ended June 30, 2015 and 2014, respectively, and (15.1)% and 43.4% for the six months ended June 30, 2015 and 2014, respectively. The decreases in the effective income tax rate were primarily due to the impact of income tax benefits for discrete items recognized in 2015, including recent changes in state and local income tax laws and the recognition of certain federal tax credits, partially offset by increases in the effective tax rate due to changes in net unrecognized tax benefits associated with state and local income tax items. Supplemental Statements of Cash Flows Information The following table summarizes T-Mobile’s supplemental cash flows information: Six Months Ended June 30, (in millions) 2015 2014 Interest and income tax payments: Interest payments, net of amounts capitalized $ 621 $ 639 Income tax payments 33 23 Noncash investing and financing activities: Increase (decrease) in accounts payable and accrued liabilities for purchases of property and equipment (173 ) 56 Issuance of short-term debt for financing of property and equipment purchases 500 255 Assets acquired under capital lease obligations 190 63

Guarantor Subsidiaries	Note 9 – Guarantor Financial Information Pursuant to the applicable indentures and supplemental indentures, the long-term debt, excluding capital leases, issued by T-Mobile USA, Inc. (“Issuer”) is fully and unconditionally guaranteed, jointly and severally, on a senior unsecured basis by T-Mobile (“Parent”) and certain of the Issuer’s 100% owned subsidiaries (“Guarantor Subsidiaries”). The guarantees of the Guarantor Subsidiaries are subject to release in limited circumstances only upon the occurrence of certain customary conditions. The indentures governing the long-term debt contain covenants that, among other things, limit the ability of the Issuer and the Guarantor Subsidiaries to: incur more debt; pay dividends and make distributions; make certain investments; repurchase stock; create liens or other encumbrances; enter into transactions with affiliates; enter into transactions that restrict dividends or distributions from subsidiaries; and merge, consolidate, or sell, or otherwise dispose of, substantially all of their assets. Certain provisions of each of the indentures and the supplemental indentures relating to the long-term debt restrict the ability of the Issuer to loan funds or make payments to Parent. However, the Issuer and Guarantor Subsidiaries are allowed to make certain permitted payments to the Parent under the terms of the indentures and the supplemental indentures. Presented below is the condensed consolidating financial information as of June 30, 2015 and December 31, 2014 and for the three and six months ended June 30, 2015 and 2014 , respectively.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	The unaudited condensed consolidated financial statements of T-Mobile US, Inc. (“T-Mobile” or the “Company”) include all adjustments of a normal recurring nature necessary for the fair presentation of the results for the interim periods presented. The results for the interim periods are not necessarily indicative of those for the full year. The condensed consolidated financial statements should be read in conjunction with the Company’s consolidated financial statements included in the Annual Report on Form 10-K for the year ended December 31, 2014 . Certain prior period amounts have been reclassified to conform to the current presentation.
Principles of Consolidation	The condensed consolidated financial statements include the balances and results of operations of T-Mobile and its consolidated subsidiaries. T-Mobile consolidates all majority-owned subsidiaries over which it exercises control, as well as variable interest entities (“VIE”) where it is deemed to be the primary beneficiary and VIEs which cannot be deconsolidated. Intercompany transactions and balances have been eliminated in consolidation.
Use of Estimates	The preparation of financial statements in conformity with United States (“U.S.”) generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions which affect the financial statements and accompanying notes. Estimates are based on historical experience, where applicable, and other assumptions which management believes are reasonable under the circumstances. These estimates are inherently subject to judgment and actual results could differ from those estimates.
Recently-Issued Accounting Standards	Recently-Issued Accounting Standards In April 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2015-03, “Simplifying the Presentation of Debt Issuance Costs.” The standard requires 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 recognition and measurement guidance for debt issuance costs are not affected. The standard will become effective for T-Mobile beginning January 1, 2016. The implementation of this standard is not expected to have a significant impact on T-Mobile’s consolidated financial statements. In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers.” The standard requires entities to recognize revenue through the application of a five-step model, which includes identification of the contract, identification of the performance obligations, determination of the transaction price, allocation of the transaction price to the performance obligations, and recognition of revenue as the entity satisfies the performance obligations. In July 2015, the FASB voted to defer the effective date by one year to periods beginning January 1, 2018; however, early adoption with the original effective date for periods beginning January 1, 2017 will be permitted. The Company is currently evaluating the guidance to determine the potential impact on T-Mobile’s consolidated financial statements.
