T-Mobile Network Advancements Enrich Customer Experience with Nationwide HD Voice and Enhanced 4G Coverage in New Metro Areas

T-Mobile is the first U.S. wireless provider to launch HD Voice nationwide

Las Vegas, Nev. — Jan. 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, improving signal strength and in-building coverage and re-tuning its airwaves to launch 4G service in an additional frequency, 1900 MHz, providing a 4G experience to a broader range of consumer devices, including the iPhone. Today T-Mobile is adding new metro areas, including Denver, Los Angeles, San Diego and Virginia Beach, Va. These network enhancements now reach 126 million people in 46 metro areas including major cities such as Atlanta, Boston, Chicago, Dallas, Detroit, Houston, Las Vegas, Miami, Minneapolis, New York, Philadelphia, Phoenix, San Francisco, Seattle and Washington, D.C.
