LAS VEGAS -- January 8, 2013

T-Mobile today announced that HD Voice is now available on its network
nationwide, dramatically improving in-call voice quality for customers with
capable smartphones. Customers will hear a more true-to-life voice quality
that’s fuller and more natural-sounding with significantly reduced background
noise from street traffic, wind and crowd noise. To experience HD Voice, both
parties on the call must use capable T-Mobile 4G smartphones such as the HTC
One^™ S, Nokia Astound and Samsung Galaxy S^® III on T-Mobile’s HD
Voice-enabled nationwide network. T-Mobile is the first U.S. wireless provider
to launch HD Voice nationwide.

“T-Mobile is enriching the customer experience on its network with our
nationwide launch of HD Voice. In addition, multiple third-party tests have
shown that the experience on T-Mobile’s nationwide 4G network rivals major
competitors’ LTE networks,” said Neville Ray, chief technology officer,
T-Mobile USA. “This year, we’re stepping on the gas again. We are making
continued coverage improvements and launching an advanced LTE network that
will reach 100 million people by mid-year and 200 million people by end of
year.”

T-Mobile’s $4 billion plan to advance its competitive 4G network continues,

experience to a broader range of consumer devices, including the iPhone. Today
