Preparation of Interim Financial Statements	'
	Preparation of Interim Financial Statements — Our condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) and the rules and regulations of the United States Securities and Exchange Commission (the “SEC”). Amounts shown on the condensed consolidated statements of income within the operating expense categories of cost of revenue; service, rental and maintenance; selling and marketing; and general and administrative are recorded exclusive of severance and restructuring costs, depreciation, amortization and accretion. These items are shown separately on the condensed consolidated statements of income within operating expenses. Foreign currency translation adjustments were deemed immaterial and consequently, no statements of comprehensive income are presented.
	The financial information included herein, other than the condensed consolidated balance sheet as of December 31, 2012, is unaudited. The condensed consolidated balance sheet at December 31, 2012 has been derived from, but does not include all the disclosures contained in the audited consolidated financial statements for the year ended December 31, 2012. In management’s opinion, our unaudited condensed consolidated statements include all adjustments and accruals that are necessary for a fair presentation of the results of all interim periods reported herein.
	These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and accompanying notes included in USA Mobility’s Annual Report on Form 10-K for the year ended December 31, 2012 (the “2012 Annual Report”).

Goodwill and Intangible Assets Disclosure [Abstract]	'
Goodwill and Amortizable Intangible Assets	'
	Goodwill and Amortizable Intangible Assets — Goodwill at September 30, 2013 and December 31, 2012 was $133.0 million, which is all attributed to our software operations. Goodwill is not amortized but is evaluated for impairment at least annually, or when events or circumstances suggest a potential impairment has occurred. We have selected the fourth quarter to perform this annual impairment test. GAAP requires the comparison of the fair value of the reporting unit to the carrying amount to determine if there is potential impairment. For this determination, all of our goodwill has been assigned to our software segment, which is also deemed to be the reporting unit. The first step of the impairment test involves comparing the fair value of the reporting unit with its carrying value. If the reporting unit’s fair value is less than the carrying amount of the reporting unit, we perform the second step of the goodwill impairment test. The second step of the goodwill impairment test involves comparing the implied fair value of the affected reporting unit’s goodwill with the carrying value of that goodwill. The amount, by which the implied fair value is less than the carrying value of the goodwill, if any, is recognized as an impairment loss. The fair value of the reporting unit is estimated using a discounted cash flow methodology. This analysis requires significant judgments, including estimation of future cash flows, which is dependent on internal forecasts, estimation of the long-term rate of growth for our business, estimation of the useful life over which cash flows will occur, and determination of our weighted average cost of capital. There were no indicators of impairment for the nine months ended September 30, 2013.
	Amortizable intangible assets for software operations include customer related intangibles, technology based intangibles, contract based intangibles and marketing intangibles and resulted from our acquisition of Amcom in 2011 and IMCO Technologies Corporation (“IMCO”) in 2012. Such intangibles are being amortized over periods ranging from two to fifteen years. The amortization related to the non-compete agreement for a former executive in our wireless operations was fully recognized at September 30, 2013.
	The gross carrying amount of amortizable intangible assets was $41.5 million at September 30, 2013 and the accumulated amortization was $14.9 million. The net consolidated balance of amortizable intangible assets consisted of the following:
				September 30, 2013

Asset Retirement Obligation Disclosure [Abstract]	'
Asset Retirement Obligations	'
	Asset Retirement Obligations — We recognize liabilities and corresponding assets for future obligations associated with the retirement of assets. We have paging equipment assets, principally transmitters, which are located on leased locations. The underlying leases generally require the removal of equipment at the end of the lease term; therefore, a future obligation exists.
	At January 1, 2013, we had recognized cumulative asset retirement costs of $1.7 million. During the nine months ended September 30, 2013, we recorded an increase of $0.1 million in asset retirement costs for a total of $1.8 million at September 30, 2013. The asset retirement cost additions during the nine months ended September 30, 2013 increased paging equipment assets and are being depreciated over the related estimated lives of 51 to 57 months. The asset retirement costs and the corresponding liabilities that have been recorded to date generally relate to either current plans to consolidate networks or to the removal of assets at an estimated future terminal date.
	The components of the changes in the asset retirement obligation liabilities were:
			Short-Term			Long-Term			Total
			Portion			Portion
			(Dollars in thousands)
	Balance at January 1, 2013		$	379		$	7,557		$	7,936

	(1)	Difference in accretion from accretion expense in Note 7 is due to accretion on the IMCO royalty payable.
	The balances above were included with accounts payable and accrued liabilities and other long-term liabilities, respectively, at September 30, 2013.

Revenue Recognition [Abstract]	'
Deferred Revenue	'
	Deferred Revenue — Deferred revenue on a consolidated basis at September 30, 2013 was $28.0 million for the current portion and $0.4 million for the non-current portion. Deferred revenue at September 30, 2013 primarily consisted of unearned maintenance, license and professional services revenue and customer deposits for installation services related to our software operations. Unearned maintenance revenue represented a contractual liability to provide maintenance support over a defined period of time for which payment has generally been received. Unearned license and professional services revenue represented a contractual liability to provide professional services more substantive than post contract support. At September 30, 2013, we had received $5.8 million in customer deposits for future installation services. We will recognize revenue when the service or software is delivered and all other revenue recognition criteria have been satisfied.

Debt Disclosure [Abstract]	'
Long-Term Debt	'
	Long-Term Debt — On November 8, 2011, we executed the First Amendment to our Amended and Restated Credit Agreement (“Amended Credit Agreement”) with Wells Fargo Capital Finance, LLC (“Wells Fargo”). The Amended Credit Agreement increased the amount of the revolving credit facility to $40.0 million. The maturity date for the revolving credit facility is September 3, 2015. We may make a London Interbank Offered Rate (“LIBOR”) election for any amount of our debt for a period of one, two or three months at a time; however, we may not have more than five individual LIBOR loans in effect at any given time. We may only exercise the LIBOR rate election for an amount of at least $1.0 million.
	Borrowings under this facility are secured by a lien on substantially all of our existing assets, interests in assets and proceeds owned or acquired by us. We had no outstanding borrowings under this revolving credit facility as of September 30, 2013.
	We are exposed to changes in interest rates should we have borrowings under the revolving credit facility. The floating interest rate debt exposes us to interest rate risk, with the primary interest rate exposure resulting from changes in LIBOR.
	We are subject to certain financial covenants on a quarterly basis under the terms of the Amended Credit Agreement. These financial covenants consist of a leverage ratio and a fixed charge coverage ratio. We were in compliance with all of the required financial covenants as of September 30, 2013.
	We have also established control agreements with the financial institutions that maintain our cash and investment accounts. These agreements permit Wells Fargo to exercise control over our cash and investment accounts should we default under provisions of the Amended Credit Agreement. We are not in default under the Amended Credit Agreement and do not anticipate that Wells Fargo would need to exercise its rights under these control agreements during the term of the Amended Credit Agreement.

	2009 LTIP. On December 31, 2012, the cash and equity awards under the 2009 LTIP vested when the pre-established performance goals were achieved. After the filing of the 2012 Annual Report, the Company converted 258,730 RSUs into shares of common stock under the 2004 Equity Plan on April 19, 2013 and paid $1.5 million in accumulated cash dividends earned on the RSUs to the eligible employees on April 26, 2013. The cash awards totaling $3.0 million under the 2009 LTIP were also paid to the eligible employees on April 26, 2013. These amounts were reflected in accounts payable and accrued liabilities and accrued compensation and benefits, respectively, as of December 31, 2012.
	2011 LTIP. During the first quarter of 2013, our Board of Directors awarded 20,676 RSUs to eligible employees in the software operations, partially offset by 2,781 RSUs forfeited by a former employee in the software operations. During the second quarter of 2013, our Board of Directors awarded 3,518 RSUs to an eligible employee in the software operations. During the third quarter of 2013, our Board of Directors awarded 17,898 RSUs to eligible employees in the software operations, offset by 19,725 RSUs forfeited by former employees in the software operations under the 2011 LTIP. The Board of Directors granted these RSUs under the 2012 Equity Plan pursuant to a Restricted Stock Agreement. At September 30, 2013, 252,552 RSUs were outstanding for the software operations.
	On January 22, 2013 (the grant date) and effective for January 1, 2013, our Board of Directors awarded 253,739 RSUs to eligible employees in the wireless operations under the 2011 LTIP. The Board of Directors granted these RSUs under the 2012 Equity Plan pursuant to a Restricted Stock Agreement.
	On July 23, 2013 (the grant date), the Board of Directors awarded the President and Chief Executive Officer (“CEO”) an additional 138,980 RSUs under the 2011 LTIP pursuant to his amended employment agreement dated July 29, 2013. The RSUs were granted under the 2012 Equity Plan.
	On July 26, 2013, 2,689 RSUs were forfeited by a former employee in the wireless operations. At September 30, 2013, 390,030 RSUs were outstanding for the wireless operations.

	Board of Directors Equity Compensation. On August 1, 2007, for periods of service beginning on July 1, 2007, our Board of Directors approved that, in lieu of RSUs, each non-executive director will be granted in arrears on the first business day following the quarter of service, restricted stock under the 2004 Equity Plan or the 2012 Equity Plan for their service on the Board of Directors and committees thereof. The restricted stock will be granted quarterly based upon the closing price per share of our common stock at the end of each quarter, such that each non-executive director will receive $40,000 per year of restricted stock ($50,000 for the Chair of the Audit Committee). The restricted stock will vest on the earlier of a change in control of the Company (as defined in the 2004 Equity Plan for restricted stock granted before May 16, 2012 or the 2012 Equity Plan for grants on or after May 16, 2012) or one year from the date of grant, provided, in each case, that the non-executive director maintains continuous service on the Board of Directors. Future cash dividends related to the restricted stock will be set aside and paid in cash to each non-executive director on the date the restricted stock vests. In addition to the quarterly restricted stock grants, the non-executive directors will be entitled to cash compensation of $40,000 per year ($50,000 for the Chair of the Audit Committee), also payable quarterly. These sums are payable, at the election of the non-executive director, in the form of cash, shares of common stock, or any combination thereof.
	On July 23, 2013, for the period of service beginning on July 1, 2013, our Board of Directors approved a change in the non-executive directors’ compensation plan. The non-executive directors will receive restricted stock quarterly based upon the closing price per share of our common stock at the end of each quarter, such that each non-executive director will receive $60,000 per year of restricted stock ($70,000 for the Chair of the Audit Committee). The restricted stock will vest on the earlier of a change in control of the Company (as defined in the 2012 Equity Plan) or one year from the date of grant, provided, in each case, that the non-executive director maintains continuous service on the Board of Directors. Future cash dividends related to the restricted stock will be set aside and paid in cash to each non-executive director on the date the restricted stock vests. The non-executive directors are required to hold shares of common stock and/or restricted stock equal to three times their annual cash compensation ($135,000 for each non-executive director and $165,000 for the Chair of the Audit Committee) as measured on June 30th of each year. Should the value of the non-executive director’s holdings fall below the established minimum, the non-executive director will be deemed in compliance with the requirement provided that the non-executive director retained shares equal to the total number of restricted stock granted during the preceding three years. All non-executive directors will have a three year grace period to reach this ownership threshold. In addition to the quarterly restricted stock grants, the non-executive directors will be entitled to cash compensation of $45,000 per year ($55,000 for the Chair of the Audit Committee), also payable quarterly. These sums are payable, at the election of the non-executive director, in the form of cash, shares of common stock, or any combination thereof.
	The following table details information on the restricted stock awarded to or vested by the non-executive directors in 2012 and 2013:

	(1)The quarterly restricted stock awarded is based on the price per share of our common stock on the last trading day prior to the quarterly award date.
	(2)The difference between restricted stock awarded and restricted stock awarded and outstanding is due to Mr. Heim's forfeitures of 2,452 restricted stock
	due to his voluntary resignation to the Board.
	(3)Amount excludes interest earned and paid upon vesting of shares of restricted stock.
	Board of Directors Common Stock. No directors have elected common stock in lieu of cash payments for their services during the nine months ended September 30, 2013.
	The following table reflects the stock based compensation expense for the awards under the Equity Plans:
			For the Three Months Ended September 30,								For the Nine Months Ended September 30,

Total stock based compensation		$	946			$	460			$	2,200			$	902
The 2009 LTIP vested on December 31, 2012, as such, no stock based compensation expense was incurred in 2013. The 2011 LTIP was awarded to the eligible employees in the wireless operations effective for January 1, 2013, which resulted in an increase in stock based compensation expense in 2013. Stock based compensation expense for the nine months ended September 30, 2012 in software operations reflects forfeitures under the 2011 LTIP associated with the departure of two former executives.
Cash Dividends to Stockholders. The following table details our cash dividend payments made in 2013. Cash dividends paid as disclosed in the statements of cash flows for the nine months ended September 30, 2013 and 2012 included previously declared cash dividends on shares of vested restricted stock issued to our non-executive directors and vested RSUs issued to eligible employees under the 2009 LTIP. Cash dividends on the RSUs and restricted stock have been accrued and are paid when the applicable vesting conditions are met. Accrued cash dividends on forfeited restricted stock and RSUs are also forfeited.
Declaration Date		Record Date		Payment Date		Per Share Amount				Total  Payment(1)

(1)	The total payment reflects the cash dividends paid in relation to common stock, vested restricted stock and vested RSUs.
(2)	The payment reflects the accumulated cash dividends earned on vested RSUs associated with the 2009 LTIP.
Future Cash Dividends to Stockholders. On November 5, 2013, our Board of Directors declared a regular quarterly cash dividend of $0.125 per share of common stock, with a record date of November 20, 2013, and a payment date of December 10, 2013. This cash dividend of approximately $2.7 million will be paid from available cash on hand.
Common Stock Repurchase Program. On July 31, 2008, our Board of Directors approved a program to repurchase up to $50.0 million of our common stock in the open market during the twelve-month period commencing on or about August 5, 2008. This program has been extended at various times, most recently through December 31, 2013 with a repurchase authority of $25.0 million. We made no common stock repurchases during the nine months ended September 30, 2013. There is approximately $17.0 million of common stock repurchase authority remaining under the program as of September 30, 2013.
Repurchased shares of our common stock were accounted for as a reduction to common stock and additional paid-in-capital in the period in which the repurchase occurred. All repurchased shares of common stock are returned to the status of authorized, but unissued, shares of the Company.
Additional Paid-in Capital. For the nine months ended September 30, 2013, additional paid-in capital increased by $1.2 million to $126.4 million at September 30, 2013 from $125.2 million at December 31, 2012. The increase in the nine months ended September 30, 2013 was due primarily to amortization of stock based compensation and a net settlement of common stock awards under the 2012 STIP and the 2009 LTIP.
Net Income per Common Share. Basic net income per common share is computed on the basis of the weighted average common shares outstanding. Diluted net income per common share is computed on the basis of the weighted average common shares outstanding plus the effect of all potentially dilutive common shares including outstanding restricted stock and RSUs, which are treated as contingently issuable shares, using the “treasury stock” method. During the second quarter of 2013, we acquired a net total of 108,459 shares of common stock after settling vested awards under the 2012 STIP and the 2009 LTIP. These shares of common stock acquired were retired and excluded from our reported outstanding share balance as of September 30, 2013. The components of basic and diluted net income per common share were as follows for the periods stated:
		For the Three Months Ended September 30,								For the Nine Months Ended September 30,

Income Taxes	'
	Income Taxes — We file a consolidated U.S. Federal income tax return and income tax returns in state, local and foreign jurisdictions (Canada and Australia) as required.
	At September 30, 2013, we had total deferred income tax assets of $152.3 million and a valuation allowance of $118.7 million resulting in an estimated recoverable amount of deferred income tax assets of $33.6 million. This reflected a change from the December 31, 2012 balance of deferred income tax assets of $163.9 million and a valuation allowance of $118.7 million resulting in an estimated recoverable amount of $45.2 million. The change reflects the expected usage of the deferred income tax assets based on estimated 2013 taxable income.
	At both September 30, 2013 and December 31, 2012, the balance of the valuation allowance was $118.7 million, respectively, which did not include any valuation allowance for foreign operations.
	We consider both positive and negative evidence when evaluating the recoverability of our deferred income tax assets. The assessment is required to determine whether based on all available evidence, it is more likely than not (i.e., greater than a 50% probability) whether all or some portion of the deferred income tax assets will be realized in the future. During the fourth quarter of each year, we prepare a multi-year forecast of taxable income for our operations. The wireless operations have experienced a continuing decline in revenues and taxable income as subscribers switch to other communication solutions. The software operations have been impacted by the economic uncertainty of the past several years which has impacted customer purchase and implementation decisions. The forecasts of taxable income are not sufficient to result in the full realization of our deferred income tax assets.
	The anticipated effective income tax rate is expected to continue to differ from the Federal statutory rate of 35% primarily due to the effect of state income taxes, the effect of changes to the deferred income tax asset valuation allowance, permanent differences between book and taxable income and certain discrete items.
	As of January 1, 2013, we had approximately $389.1 million of Federal net operating losses (“NOLs”) available to offset future taxable income. The IRC Section 382 limited NOLs as of January 1, 2013 totaled $56.5 million which may be used at a rate of $6.1 million per year. The 2012 NOL utilized was $41.3 million, which is net of the Internal Revenue Code Section 382 (“IRC Section 382”) limitation.

Segment Reporting	'
	Segment Reporting — Currently, we have two reportable operating segments: a Wireless segment and a Software segment. These segments are operated and managed as strategic business units and are organized by products and services. We measure and evaluate our segments based on segment operating income, consistent with the chief operating decision maker’s assessment of segment performance.
	Our segments and their principal activities consist of the following:
	Wireless		Provides local, regional and nationwide one-way paging and advanced two-way messaging services and mobile voice and data services through third party providers.
	Software		Provides mission critical unified communications solutions for contact centers, emergency management, mobile event notification and messaging.
	We use a non-GAAP financial measure as a key element in determining performance for purposes of incentive compensation under our annual STIP. That non-GAAP financial measure is operating cash flow (“OCF”), defined as earnings before interest, taxes, depreciation, amortization and accretion (“EBITDA”) less purchases of property and equipment. (EBITDA is defined as operating income plus depreciation, amortization and accretion, each determined in accordance with GAAP). The following table presents the key financial metrics of our segments for the periods stated:
