Un-carrier momentum carries T-Mobile past Sprint, AT&T and Verizon for top spot in prepaid wireless market, brings new level of customer service and network quality to growing prepaid marketplace

BELLEVUE, Washington—August 6, 2014—On the heels of yet another strong quarterly performance report, T-Mobile US Inc. (NYSE: TMUS) today announced the Un-carrier has overtaken rivals AT&T, Verizon and Sprint to become the No.1 U.S. wireless provider in the increasingly important prepaid mobile marketplace.

According to the most recent reported figures, T-Mobile US now boasts 15.64 million prepaid customers compared to Sprint’s 15.19 million customers in the prepaid market. AT&T most recently reported 11.34 million prepaid customers. Verizon Wireless reports 6.04 million prepaid customers.

“The good news just keeps on coming for T-Mobile,” said John Legere, president and CEO of T-Mobile US, Inc. “The momentum we’re seeing with our T-Mobile and MetroPCS brands is outstanding, and the fact that we’ve blown by everyone to take the No.1 spot in prepaid is icing on the cake. As a matter of fact, I’m going on record—I predict we’ll overtake Sprint in total customers by the end of this year. Not someday. Not next year. This year. Americans are voting with their feet, and they’re joining this Un-carrier revolution by the millions.”

Providers have been placing increasing emphasis on this important area of the mobile marketplace. Still, no wireless company has seen nearly the success the Un-carrier has in this critical market.

The Un-carrier’s MetroPCS brand in particular has seen unprecedented gains since merging with T-Mobile on May 1st of last year. MetroPCS effectively tripled its market reach to 45 major metro areas and nearly 10,000 stores, while migrating its customers onto America’s fastest nationwide 4G LTE network. This aggressive expansion of markets and coverage has led MetroPCS to grow to over 10 million customers—and the numbers continue to climb.

In fact, with over 1.2 million new customers since this time last year, MetroPCS has been adding customers at a rate of one customer every 27 seconds.

With T-Mobile US now solidly in the lead in the important prepaid wireless space, the Un-carrier is clearly firing on all cylinders. Since the start of the year, T-Mobile has maintained the undisputed title of America’s fastest nationwide 4G LTE network—as proven yet again by CNET’s most recent industry-wide tests. Further, the Un-carrier now has over 50 million customers–and shows no signs whatsoever of slowing down. In the second quarter of 2014, T-Mobile US added 1.5 million net new customers for a fifth straight quarter with over 1 million total net new customers. And the Un-carrier again led the overall industry in growth, beating out rivals AT&T, Verizon and Sprint.

“Not only are we seeing record growth, we’re also making huge strides on our network and in customer support,” said Legere. “Our 4G LTE network is still the fastest in the nation, and both T-Mobile and MetroPCS brands have the highest J.D. Power scores for customer care in our respective categories. Oh and today we overtook Sprint in total market cap. Any questions?”
