Un-carrier reaches interconnect and roaming agreement with Cuban telecom

to offer roaming for customers traveling to Cuba

Bellevue, Washington — May 9, 2016 —T-Mobile [NASDAQ: TMUS] today announced it has signed an interconnect and roaming agreement with Empresa De Telecomunicaciones De Cuba, S.A. (ETECSA), the Cuban telecommunications company. The new deal enables the Un-carrier to do its part to open communications between the U.S. and the island nation, delivering more affordable voice calling for customers who want to keep in touch with friends and family in Cuba, as well as voice, text and data roaming for customers traveling to Cuba starting this summer.

“The historic opening of Cuba is a natural opportunity for us to take action, and we are. That’s the Un-carrier way!” said John Legere, president and CEO of T-Mobile. “We have more customers of Cuban descent than any other wireless provider – so connecting them with family and friends in Cuba is a message we heard loud and clear!”

More than a third (36.6%) of Cuban-born wireless customers are with T-Mobile, more than AT&T and triple the number of Verizon customers. And, customers in Cuban-American hubs like Miami are choosing T-Mobile and MetroPCS nearly twice as often as AT&T or Verizon. Not surprisingly, Cuba is the #1 requested addition to T-Mobile’s international roaming on social media. Naturally, the Un-carrier is listening and responding to its customers.

As a result of today’s agreement, T-Mobile Simple Choice customers will be able to:

Call landlines and wireless phones in Cuba from the U.S. for just $0.60 per minute – 65 percent less than today – with the popular monthly “Stateside International Talk” feature ($15 per month) and

Use voice, text, and data while traveling in Cuba, starting this summer.
