Exhibit 99.3

USA MOBILITY, INC. UNAUDITED PRO FORMA

CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

      The following unaudited pro forma condensed consolidated financial statements have been prepared to give effect to the merger of Arch Wireless, Inc. and Metrocall Holdings, Inc. Pursuant to the terms of the merger agreement, Patriots Acquisition Sub, Inc. and Wizards Acquisition Sub, Inc, two wholly-owned subsidiaries of USA Mobility, Inc. (USA Mobility) will merge with and into Arch and Metrocall, respectively. USA Mobility presently has no operations and was formed specifically to facilitate the merger transaction. Under the terms of the merger agreement, holders of Arch common stock will receive one share of USA Mobility common stock for each common share held of Arch Wireless. Holders of Metrocall common stock will receive consideration totaling $150 million of cash and 7,560,515 shares of USA Mobility common stock assuming 1.876 USA Mobility shares will be exchanged for each Metrocall share not subject to the cash election. Upon consummation of the merger exchange, former Arch and Metrocall common shareholders will hold approximately 72.5% and 27.5%, respectively, of USA Mobility’s common stock on a fully diluted basis.

      These pro forma financial statements do not purport to be indicative of the consolidated financial position or results of operations for future periods or the results that actually would have been realized had the merger occurred on the dates specified in these pro forma financial statements.

      The merger will be accounted for under the purchase method of accounting pursuant to Statement of Financial Accounting Standard (SFAS) No. 141, Business Combinations. Arch Wireless, Inc. has been deemed the “accounting acquirer” as a result of its former shareholders holding a majority of the common stock of USA Mobility following the merger and Arch representatives holding five of nine board of director positions of the combined company. Accordingly, the basis of Arch’s assets and liabilities as of the acquisition date will be reflected on the balance sheet of USA Mobility at their historical basis. Amounts allocated to Metrocall’s assets and liabilities will be based upon the total purchase price and the estimated fair value of such assets and liabilities on the effective date of the merger. The purchase price allocations reflected in the accompanying pro forma condensed consolidated balance sheet were made based upon preliminary estimates and assumptions. The actual amount and allocation of purchase price may differ significantly from the pro forma amounts included herein.

      The unaudited pro forma condensed consolidated financial statements, including the notes thereto, are qualified in their entirety by reference to, and should be read in conjunction with the historical consolidated financial statements and the notes thereto of Arch included herein and Metrocall as included in Metrocall’s Annual Report on Form 10-K for the year ended December 31, 2003 or Amendment No.2 to quarterly report on form 10-Q for the three months ended March 31, 2004.

      The unaudited pro forma condensed consolidated balance sheet was prepared as if the merger occurred on March 31, 2004. The unaudited pro forma condensed consolidated statements of operations for the year ended December 31, 2003 and for the three months ended March 31, 2004 were prepared as if the merger occurred on January 1, 2003. To prepare the pro forma condensed consolidated statements of operations for the year ended December 31, 2003, Metrocall’s historical statement of operations for the year ended December 31, 2003 was combined on a pro forma basis with the historical statement of operations of WebLink Wireless for the period January 1, 2003 to November 17, 2003, as if Metrocall had acquired WebLink on January 1, 2003. Metrocall’s historical statement of operations includes the results of operations of WebLink for the period November 18 to December 31, 2003. Refer to “Metrocall Holdings, Inc. — WebLink Acquired Assets” for further information on this pro forma financial information.

NOTES TO UNAUDITED PRO FORMA CONDENSED

CONSOLIDATED FINANCIAL STATEMENTS

(1)

To record the issuance of 7,560,515 shares of $0.0001 par value USA Mobility common stock valued at $28.68 per share and $150 million of debt in exchange for all of the outstanding common stock and stock equivalents of Metrocall Holdings, Inc. The per share price was calculated by taking the average of the closing stock price of Arch common stock for the seven day period beginning three days before and ending three days after March 29, 2004, the date the merger was publicly announced. The value of Arch common stock was utilized in the purchase price calculation since Arch was deemed the “accounting acquirer”, its exchange ratio is 1 to 1 and it carries similar transfer restrictions to those of USA Mobility Common Stock. The amount of debt that will be incurred to finance the cash election is undetermined at this time, but may be as much as $150 million depending on the available cash on hand of Arch and Metrocall at the time of the closing of the merger.

The provisions of SFAS No. 141 require the purchase price to be allocated to the tangible and intangible assets acquired and liabilities assumed based upon their estimated fair values as of the consummation date. The allocation below is based on management estimates. The actual allocation may differ significantly from the pro forma amounts included below. The preliminary calculation of the purchase price, excess of purchase price over the fair value of identifiable assets acquired and the allocation of purchase price are as follows (in thousands):

Consideration Exchanged:
	Fair value of shares issued to Metrocall stockholders — 7,560,515 shares at $28.68 per share)	$	216,868
	Cash election payments		150,000
	Transaction costs		10,000	(a)
Liabilities Assumed:
	Capital leases and other long-term obligations		599
	Accounts payable		9,449
	Accrued expenses		25,451
	Customer deposits and deferred revenue		14,948
	Other liabilities		3,599
Total purchase price			430,914
Less estimated fair value of identifiable assets acquired:
	Cash and cash equivalents		9,682
	Accounts receivable, net		20,163
	Prepaid expenses and other current assets		10,019
	Property and equipment		97,489	(b)
	Other assets		4,772
	Intangible assets		288,789	(c)
		$	430,914
Excess of purchase price over the estimated fair value of identifiable assets		$	—

(a)  Primarily includes investment banking, legal, accounting and other costs, which are currently known or have been incurred. This amount may increase as additional legal, accounting, printing, financing and other costs are incurred.

(b)  The fair value of property and equipment has been estimated by management based upon historical book values and the results of valuations, adjusted by management to reflect the passage of time since the valuation was prepared, performed for the purposes of Metrocall’s fresh-start accounting and its purchase of the WebLink assets. Management believes the amounts approximate fair value,

6

however they are preliminary and may change upon preparation and completion of the third-party valuation that will be utilized in the final purchase price allocation.

(c)

Intangible assets consist primarily of assets related to customer relationships of approximately $284,489 and FCC licenses of $2,300. These assets will be amortized over their expected useful lives of 3 and 5 years, respectively. The estimated fair value of customer relationships was based upon the residual of the preliminary purchase price over the preliminary fair values of other identifiable tangible and intangible assets. The estimated fair value of FCC licenses was based on recent valuations and other studies recently performed.

If it is later determined that the fair values of property and equipment, customer relationships or FCC licenses is less than included above or the consideration exchanged is less than determined above or other intangible assets are identified, the purchase price allocations could be significantly different than stated above and any such difference could result in higher or lower amortization expense than what is reflected on the pro forma statements of operations (see note 7). Further, if the purchase price exceeds the fair value of the identifiable tangible and intangible assets, any such excess will be classified as excess of purchase price over the fair value of the identifiable tangible and intangible assets and that balance would not be amortizable, which may result in less amortization expense in future periods.

(2)	The merger agreement requires both Arch and Metrocall to have fully redeemed their 12% Subordinated Secured Compounding Notes and Series A Redeemable Preferred Stock, respectively, prior to consummation of the merger. Arch made its final redemption of its 12% notes on May 28, 2004 and Metrocall redeemed all remaining issued and outstanding shares of series A preferred on May 17, 2004. These balances were redeemed utilizing cash on hand and cash generated from the operations of each company. Consequently, for purposes of these pro forma financial statements the balances of the 12% notes and the series A preferred stock have been reduced to zero and the cash balance reduced accordingly. Additionally, the related historical interest expenses have been eliminated.
(3)	To writeoff Metrocall intangible and deferred income tax balances.
(4)	To eliminate the common stock, additional paid-in capital and retained earnings balances of Metrocall as follows:

Common stock	$	55
Additional paid-in capital	$	81,283
Metrocall retained earnings at March 31, 2004	$	20,557
Less: write-off of intangibles and deferred tax assets		(53,816	)
Adjustment to eliminate remaining retained earnings	$	(33,259	)

(5)	To record the deferred tax liability and the associated intangible asset resulting from the excess of purchase price over tax bases of the net assets acquired. As discussed above, the purchase price calculation and allocation are preliminary. SFAS No. 109, Accounting for Income Taxes, requires a deferred tax liability be recorded if the fair value of the net assets acquired exceeds the tax bases of those assets excluding any fair value allocated to goodwill (excess of purchase price over the fair value of identified assets). The amount recorded assumes the identifiable intangible assets referred to in note 1 are not goodwill and are amortizable for tax purposes. If it is later determined that the allocation of purchase price results in less intangibles and the recognition of goodwill or if the identified intangibles are not amortizable for tax purposes, that balance of the assets would be reduced or removed from the deferred tax assessment and would likely result in the recording of a lower deferred tax liability.
(6)	To record a restructuring charge in accordance with SFAS No. 146, Accounting for Costs Associated with Exit or Disposal Activities, related to severance expense for certain Arch management personnel.
(7)	To remove depreciation and amortization expense related to the Metrocall tangible and intangible assets and to record depreciation and amortization expense for the tangible and intangible assets referred to above on a straight-line basis. Depreciation and amortization expense was calculated assuming a three-year average estimated useful life for customer relationships and a five year estimated useful life for FCC

7

licenses. The three year estimated useful life assumed to calculate the amortization expense reflected in the pro forma statements of operations for the customer relationship asset is consistent with current practices of both Arch and Metrocall, however, the underlying characteristics of the customer relationship asset may differ from past experience which may result in a longer or shorter estimated useful life. The estimated useful life assigned to FCC licenses is consistent with Arch’s historical accounting policy. As discussed above, the amount, classification and estimated useful lives of the tangible and intangible assets are preliminary and based on management estimates. If any of these estimates change, the amount of depreciation and amortization expense could change materially.

(8)

To remove the historical Arch and Metrocall interest expenses associated with notes and preferred stock since the merger agreement requires both companies to fully redeem all of their debt prior to consummation of the merger and to record interest expense associated with the borrowings to finance the Metrocall cash election consideration. Interest expense was calculated using an assumed 8% rate on $150 million of borrowings resulting in $12 million and $3 million for the year ended December 31, 2003 and the three months ended March 31, 2004, respectively.

Interest expense on these borrowings would be as follows if interest rates were to increase or decrease by  1/8 of a percent (in thousands):

			Three Months
	Year Ended		Ended
	December 31,		March 31,
Assumed Change In Rate	2003		2004
Increase of  1/8%	$	12,188	$	3,047
Decrease of  1/8%	$	11,813	$	2,953

(9)  Arch has a long-term incentive plan for which compensation expense is recognized ratably over a 38 month service period which commenced on January 1, 2003. At March 31, 2004, other long-term liabilities includes $4.6 million related to this plan which represents the obligations due to plan participants as of the balance sheet date. In the event there is a “change in control” of Arch, as defined in the plan document, vesting would accelerate and result in an additional liability of $7.1 million. The board of directors of Arch and Metrocall have determined the merger does not constitute a change in control of Arch, therefore this additional amount has not been reflected in these pro forma financial statements. The liability at March 31, 2004 was valued at $26.88 per share, determined in accordance with the plan. The incentive payable in accordance with this plan is directly attributable to the performance of Arch’s common stock. An increase or decrease of one dollar in the per share price of Arch’s common stock will result in increases or decreases of up to $437,000 for each dollar fluctuation in the total amount payable in accordance with this plan.

(10)	The shares to be issued to Arch shareholders and the exchange ratio assume among other things, that 184,230 shares of Arch restricted stock held by three senior Arch executives will be repurchased by USA Mobility pursuant to the termination provisions of the restricted stock agreements. Although the employment of these three executives is expected to terminate upon consummation of the merger, if any of these executives are not terminated prior to completion of the merger, the number of shares issued to Arch shareholders would increase which would result in a change in the exchange ratio for Metrocall shareholders so that Arch and Metrocall shareholders maintain their approximate 72.5% and 27.5% ownership percentages of USA Mobility, respectively.
(11)	To eliminate legal, accounting and other expenses directly related to the merger incurred and expensed by Metrocall. Metrocall expensed these costs since Arch has been deemed the accounting acquirer.
(12)	To adjust income tax expense to the anticipated effective rate of approximately 40%.

NOTES TO THE UNAUDITED PRO FORMA STATEMENT OF OPERATIONS

(Dollars in thousands)

(1)	Represents the elimination of revenues recorded by WebLink and expenses incurred by Metrocall for airtime services provided to Metrocall by WebLink under various operating arrangements.
(2)	Represents the adjustment required to reduce WebLink’s historical depreciation and amortization expenses to the expense that Metrocall would have recognized for the period had the transaction occurred on January 1, 2003. Purchase consideration allocated to fixed assets are being depreciated over the average useful lives of the various fixed assets acquired consistent with Metrocall’s long-lived asset accounting policies. Amounts allocated to intangible assets with definite useful lives are being amortized over such useful lives estimated to be a 3 year period for customer contracts and a 5 year period for trademarks and names. Amounts allocated to intangible assets with an indefinite life such as FCC licenses are not amortized but tested for impairment on an annual basis or more frequently if changes in circumstances indicate that the asset might be impaired. Please refer to the notes to the consolidated financial statements included in Metrocall’s Annual Report on Form 10-K for the year ended December 31, 2003.
(3)	Represents the elimination of historical interest expenses of WebLink as no long-term debt was acquired in the transaction and the elimination of accretion related to accrued long-term engineering charges that had been reflected on Metrocall’s balance sheet as of the acquisition date. This obligation was eliminated as a result of the transaction.
(4)	Represents the elimination of historical losses on early extinguishment of debt of WebLink as no long-term debt was acquired in the transaction.
(5)	Represents additional income tax expense based on the results of the acquired assets for the period at Metrocall’s statutory tax rates.
