T-Mobile to Offer Samsung Galaxy S 4 at $99.99 Down

America's Un-carrier provides unparalleled Samsung Galaxy S 4 experience with lowest device upfront price, no annual service contract and unlimited data on a fast, nationwide 4G network

BELLEVUE, Wash. - June 12, 2013 - T-Mobile US, Inc. (NYSE: TMUS) continues to deliver on its Un-carrier promise of providing consumers with affordable, unrestricted and hassle-free ways to get the latest 4G LTE smartphones by offering the highly popular Samsung Galaxy S ® 4 at the low upfront price of $99.99 down, plus 24 monthly payments of $20 [1]. This limited-time promotion is available starting today, June 12, through July 13, 2013, and allows consumers to get the device for less upfront at activation than at the other major national carriers [2].

"People told us we'd be crazy to drop our price on the hot-selling Galaxy S 4 when we already offer such a low-out-of-pocket cost - so we did it," said Mike Sievert, chief marketing officer, T-Mobile US. "Some of our competitors require customers to sign a restrictive two year service contract or participate in a complicated trade-in scheme to get to their advertised price. We decided to just give customers the phone they want at the out of pocket cost they are asking for. That's what you strive to do when you are America's Un-carrier."

In addition to the Galaxy S 4, T-Mobile is lowering the upfront costs for two more highly desirable Samsung 4G LTE devices. For well-qualified customers, the Samsung Galaxy Note® II will be available at $169.99 down, plus 24 monthly payments of $20 and the Samsung Galaxy S® III will be available for $49.99 down, plus 24 monthly payments of $20. When combined with T-Mobile's Simple Choice Plan, customers will have access to the latest 4G LTE smartphones, as well as unlimited data, at a price point that's sure to meet the needs of a variety of budgets.

Simple Choice Plan

T-Mobile's Simple Choice Plan starts with a base rate of $50 per month for unlimited talk, text and Web with 500MB of high-speed data at up to 4G speeds. Consumers can add up to 2GB of high-speed data for $10 per month per line or get unlimited 4G data for an additional $20 per month per line and up to 500MB of tethering. Customers can add a second phone line for $30 per month, and each additional line is just $10 per month. There are no caps and no overages on our network, and no restrictive annual service contracts.

T-Mobile 4G LTE Network

T-Mobile's 4G LTE rollout complements its existing nationwide 4G network that covers 228 million people, which third-party tests show already rivals or beats existing LTE networks in many markets. T-Mobile's advanced 4G LTE network is currently available in seven metropolitan areas: Baltimore; Houston; Kansas City; Las Vegas; Phoenix; San Jose, Calif.; and Washington, D.C. The company expects to reach 100 million people with 4G LTE by midyear and 200 million nationwide by the end of 2013. 4G LTE devices like the Galaxy S 4 will automatically and seamlessly connect to T-Mobile's nationwide 4G HSPA+ network where 4G LTE has not yet launched [3].
