In the third quarter of 2008, on a consolidated basis, MetroPCS reported gross additions of approximately 935 thousand subscribers, which represents an increase of 39% over the third quarter of 2007. Churn for the third quarter of 2008 decreased 0.4% when compared to the third quarter of 2007, and consistent with seasonal patterns, increased 0.3% to 4.8% when compared to the second quarter of 2008. MetroPCS ended the third quarter of 2008 with approximately 4.8 million subscribers, which includes net additions during the quarter of approximately 249 thousand subscribers. MetroPCS has added approximately 1.2 million subscribers during the twelve month period ended September 30, 2008, and continued to achieve incremental penetration in every Core and Expansion market.

“We are pleased to report 249 thousand net additions during a particularly challenging economic environment and in what has historically been our seasonally slowest quarter. Clearly, these results demonstrate the resiliency of the MetroPCS business and highlight the value proposition to our subscribers of our predictable, affordable and flexible service offerings,” said Roger D. Linquist, MetroPCS’ Chairman, President and Chief Executive Officer.

“We are excited about the growth potential with our recently signed roaming agreement with Leap Wireless that effectively creates super regional coverage clusters across the country, and from our planned service launches in Boston and New York.”
