Bellevue, Wash. — May. 23, 2011

T-Mobile USA, Inc. today announced a new suite of family and individual plans that expand on the exceptional value and consumer choice the company provides to make data affordable for families on America’s Largest 4G Network.

The plans, available for new and existing customers, offer single-line and multiline options with a range of price points for talk or unlimited talk, unlimited text and unlimited data — with no data overages — offering 200 MB, 2 GB, 5 GB or 10 GB of high-speed data. Each of the plans also includes unlimited nationwide T-Mobile to T-Mobile calling, and unlimited nights and weekends. T-Mobile also continues to offer one of the industry’s most affordable entry-level unlimited data plans, starting at just $10 for 200 MB of high-speed data per billing month.

Beating the competition, T-Mobile’s $139.99 unlimited family plan with unlimited talk, unlimited text and unlimited data with 2 GB of high-speed data offers a savings of more than $350 per person, per year on a two-line annual plan, compared with similar smartphones plans from AT&T, Verizon and Sprint.1

“Our new rate plans powered by America’s Largest 4G Network put us in an excellent position to capitalize on the 80 percent of wireless customers in America who want smartphones,” said Cole Brodman, chief marketing officer, T-Mobile USA. “We’re providing customers with the 4G coverage they need, an exciting portfolio of 4G smartphones, and the value and flexibility to meet the diverse desires of their entire family.”
