“We are very pleased to announce record quarterly net subscriber additions of approximately 684 thousand in the first quarter of 2009. In the midst of the ongoing challenging economic conditions, and as voice continues to go wireless, we see consumers recognizing the value of our service as well as consumers cutting the wireline cord. During the first quarter we were excited to launch our unlimited service in the New York City and Boston metropolitan areas. Our first quarter results in our Northeast Markets, including Philadelphia, were strong, with net subscriber additions of 249 thousand. Our rate of net subscriber additions has accelerated, and we have recorded over 1.6 million net subscriber additions during the last twelve months, representing total subscriber growth of approximately 37% in that period,” said Roger D. Linquist, Chairman, President and Chief Executive Officer of MetroPCS.

“This is an exciting time for MetroPCS. We intend to continue to focus on superior execution and on increasing brand awareness. While the U.S. economy continues to be challenged, I am pleased to report that the resilience of our business model and the dedication and focus of our employees enables us to once again reiterate the full year 2009 guidance we first provided in November of 2008. As the sixth largest facility-based wireless carrier in the country, we are pleased with our continued growth and we will continue to focus on providing superior value to our customers,” Linquist concluded.

Definition of Terms and Reconciliation of Non-GAAP Financial Measures

The Company utilizes certain financial measures and key performance indicators that are not calculated in accordance with GAAP to assess our financial and operating performance. A non-GAAP financial measure is defined as a numerical measure of a company’s financial performance that (i) excludes amounts, or is subject to adjustments that have the effect of excluding amounts, that are included in the comparable measure calculated and presented in accordance with GAAP in the statement of income or statement of cash flows; or (ii) includes amounts, or is subject to adjustments that have the effect of including amounts, that are excluded from the comparable measure so calculated and presented.

Average revenue per user, or ARPU, cost per gross addition, or CPGA, and cost per user, or CPU, are non-GAAP financial measures utilized by the Company’s management to judge the Company’s ability to meet its liquidity requirements and to evaluate its operating performance. Management believes that these measures are important in understanding the performance of the Company’s operations from period to period, and although every company in the wireless industry does not define each of these measures in precisely the same way, management believes that these measures (which are common in the wireless industry) facilitate key liquidity and operating performance comparisons with other companies in the wireless industry. The following tables reconcile non-GAAP financial measures with the Company’s financial statements presented in accordance with GAAP.

Page 10 of 13

ARPU — The Company utilizes ARPU to evaluate per-customer service revenue realization and to assist in forecasting future service revenues. ARPU is calculated exclusive of pass through charges that the Company collects from its customers and remits to the appropriate government agencies.

Average number of customers for any measurement period is determined by dividing (a) the sum of the average monthly number of customers for the measurement period by (b) the number of months in such period. Average monthly number of customers for any month represents the sum of the number of customers on the first day of the month and the last day of the month divided by two. The following table shows the calculation of ARPU for the periods indicated.

CPGA — The Company utilizes CPGA to assess the efficiency of its distribution strategy, validate the initial capital invested in its customers and determine the number of months to recover customer acquisition costs. This measure also allows management to compare the Company’s average acquisition costs per new customer to those of other wireless broadband PCS providers. Equipment revenues related to new customers are deducted from selling expenses in this calculation as they represent amounts paid by customers at the time their service is activated that reduce the acquisition cost of those customers. Additionally, equipment costs associated with existing customers, net of related revenues, are excluded as this measure is intended to reflect only the acquisition costs related to new customers. The following table reconciles total costs used in the calculation of CPGA to selling expenses, which the Company considers to be the most directly comparable GAAP financial measure to CPGA.

CPU — CPU is cost of service and general and administrative costs (excluding applicable non-cash stock-based compensation expense included in cost of service and general and administrative expense) plus net loss on equipment transactions unrelated to initial customer acquisition exclusive of pass through charges, divided by the sum of the average monthly number of customers during such period. CPU does not include any depreciation and amortization expense. Management uses CPU as a tool to evaluate the non-selling cash expenses associated with ongoing business operations on a per customer basis, to track changes in these non-selling cash costs over time, and to help evaluate how changes in the Company’s business operations affect non-selling cash costs per customer. In addition, CPU provides management with a useful measure to compare our non-selling cash costs per customer with those of other wireless providers. We believe investors use CPU primarily as a tool to track changes in our non-selling cash costs over time and to compare our non-selling cash costs to those of other wireless providers. Other wireless carriers may calculate this measure differently. The following table reconciles total costs used in the calculation of CPU to cost of service, which we consider to be the most directly comparable GAAP financial measure to CPU.

The Company’s senior secured credit facility calculates consolidated Adjusted EBITDA as: consolidated net income plus depreciation and amortization; gain (loss) on disposal of assets; non-cash expenses; gain (loss) on extinguishment of debt; provision for income taxes; interest expense; and certain expenses of MetroPCS minus interest and other income and non-cash items increasing consolidated net income. The Company considers Adjusted EBITDA, as defined above, to be an important indicator to investors because it provides information related to the Company’s ability to provide cash flows to meet future debt service, capital expenditures and working capital requirements and fund future growth. The Company presents Adjusted EBITDA because covenants in its senior secured credit facility contain ratios based on this measure. If the Company’s Adjusted EBITDA were to decline below certain levels, covenants in the Company’s senior secured credit facility that are based on Adjusted EBITDA, including the maximum senior secured leverage ratio covenant, may be violated and could cause, among other things, an inability to incur further indebtedness and in certain circumstances a default or mandatory prepayment under the Company’s senior secured credit facility. The Company’s maximum senior secured leverage ratio is required to be less than 4.5 to 1.0 based on Adjusted EBITDA plus the impact of certain new markets. The lenders under the senior secured credit facility use the senior secured leverage ratio to measure the Company’s ability to meet its obligations on its senior secured debt by comparing the total amount of such debt to its Adjusted EBITDA, which the Company’s lenders use to estimate its cash flow from operations. The senior secured leverage ratio is calculated as the ratio of senior secured indebtedness to Adjusted EBITDA, as defined by the senior secured credit facility. Adjusted EBITDA is not a measure calculated in accordance with GAAP, and should not be considered a substitute for, operating income (loss), net income (loss), or any other measure of financial performance reported in accordance with GAAP. In addition, Adjusted EBITDA should not be construed as an alternative to, or more meaningful than cash flows from operating activities, as determined in accordance with GAAP.

The following table shows the calculation of our consolidated Adjusted EBITDA, as defined in the Company’s senior secured credit facility, for the three months ended March 31, 2009 and 2008.

In addition, for further information, the following table reconciles consolidated Adjusted EBITDA, as defined in our senior secured credit facility, to cash flows from operating activities for the three months ended March 31, 2009 and 2008.
