T-Mobile USA, Inc. ("T-Mobile USA”), the U.S. operation of Deutsche Telekom AG’s ("Deutsche Telekom” (NYSE:DT)) Mobile Communications business, today announced fourth quarter and full year 2007 customer results. "T-Mobile continues to drive year-over-year growth by pioneering innovation that matters to consumers,” said Robert Dotson, CEO and President, T-Mobile USA. "In 2007, we increased growth to over 3.6 million net new customers. myFavesSM was a major contributor to this growth, with 5 million customers at year-end using the service to make unlimited calls to the people who matter most to them. Part of this growth was also fueled by the debut of FlexPaySM, a new option in the market that opens up access to more attractive offerings for certain classes of customers. In 2007, we also introduced our revolutionary HotSpot @HomeSM service to rave reviews for how we’re opening up new value alternatives for land line customers – all while we add outstanding call quality improvements in homes across America.” In the fourth quarter of 2007, T-Mobile USA added 951,000 net new customers compared to 857,000 in the third quarter of 2007 and 901,000 in the fourth quarter of 2006.
