T-Mobile announced highlights of the company’s wireless network expansion plans, including the deployment of its third-generation (3G) wireless broadband service to 27 major markets in the United States by the end of 2008. The planned expansion is expected to deliver T-Mobile 3G services to more than two-thirds of T-Mobile’s current data customers, with meaningful expansion to additional customers and markets through 2009.

T-Mobile’s UMTS/HSDPA high-speed data network is currently available across 13 major metropolitan markets: Austin, Baltimore, Boston, Dallas, Houston, Las Vegas, Miami, Minneapolis, New York (including northern New Jersey and Long Island), Phoenix, Portland, San Antonio and San Diego. The company plans to expand its service by mid-October to additional markets, including Atlanta, Chicago, Los Angeles, Orlando, Philadelphia, Sacramento, San Francisco and Seattle. An additional six markets–Birmingham, Denver, Detroit, Kansas City, Memphis and Tampa–are expected to have the network available before the end of the year, increasing the number of markets with T-Mobile’s 3G network to 27 markets.
