MetroPCS Pre-Releases First Quarter 2008 Subscriber Results

DALLAS (April 7, 2008) — MetroPCS Communications, Inc. (NYSE: PCS), the nation’s leading provider of unlimited wireless communications service for a flat-rate with no signed contract, today announced selected subscriber information for the quarter ended March 31, 2008.

In the first quarter of 2008, on a consolidated basis, MetroPCS reported gross additions of approximately 960 thousand subscribers, which represents an increase of 15% over the first quarter of 2007. Churn for the first quarter of 2008, consistent with seasonal patterns, declined 0.8% to 4.0% when compared to the fourth quarter of 2007 and was unchanged when compared to the first quarter of 2007. MetroPCS ended the first quarter with approximately 4.4 million subscribers, which includes net additions during the quarter of approximately 452 thousand subscribers. MetroPCS has added over 750 thousand subscribers during the most recent six month period ended March 31, 2008, representing total subscriber growth of approximately 20% as compared to subscribers as of September 30, 2007.

“With over three quarters of a million net subscriber additions in the last six months, consumers continue to see the extraordinary value proposition that MetroPCS provides to those who want unlimited wireless service at a compelling price. We also continue to benefit from the ongoing landline replacement trend in the U.S.,” said Roger D. Linquist, MetroPCS’ Chairman, President and Chief Executive Officer.

“Growth in Los Angeles continued to accelerate throughout the first quarter driven by ongoing expansion of our service footprint and our distribution network within the Los Angeles metropolitan area. First quarter net subscriber additions were approximately 452 thousand, highlighted by strong results in all our markets, including 13% year-over-year Core Market subscriber growth and 78% year-over-year Expansion Market subscriber growth. At the end of the first quarter, our consolidated subscriber base was over 4.4 million, representing 30% growth when compared to the first quarter of 2007. While the fourth and first calendar quarters have traditionally represented our strongest seasonal quarters, we believe our results are very strong given the overall challenging macro-economic environment in the U.S. We are encouraged by our results and believe that our competitive differentiators, continued expansion of service in Los Angeles, recent launch of Las Vegas, the first commercially launched AWS market in the country, and our planned future service launches in New York, Philadelphia, and Boston, will fuel continued customer growth.”
