News T-Mobile Receives Highest Marks for Wireless Call Quality, According to J.D. Power and Associates Study

In Regions Covering 28 of the 48 Contiguous States, T-Mobile USA Receives Highest Rankings for Call Quality

T-Mobile USA, Inc. executed in 2005 the largest network build-out in its history, reflecting the company’s continued focus and commitment to improving network coverage and quality. Now, there are significant signs that T-Mobile customers are reaping the benefits of an even stronger T-Mobile wireless network.

According to the J.D. Power and Associates 2006 Wireless Call Quality Performance StudySM – Volume 1 released today, T-Mobile overall ranked highest among wireless carriers for call quality in three of the six regions surveyed: West and Southwest outright; and Northeast in a tie.

T-Mobile was highest, or tied for highest, in providing the highest wireless call quality in regions covering 28 of the 48 contiguous states.

“These strong call-quality results for T-Mobile are a further demonstration that our continued focus on enhancing the customer experience is paying off,” said Neville Ray, senior vice president for Engineering & Operations, T-Mobile USA. “Network coverage and quality have been significantly enhanced where our customers live, work and play, and this study is the latest affirmation of our progress.”

The study provides a detailed report card based on consumers’ experiences using a diary approach – recording the most recent information pertaining to any issue they may have experienced with their wireless service.

T-Mobile’s showing was particularly strong versus the regional average in several specific areas:

  • In the West, T-Mobile was significantly stronger when it came to attaining a connection on the first try and yielding the fewest number of dropped calls.
  • In the North Central, T-Mobile rated significantly better in the number of dropped calls and in the amount of echo on the line.
  • In the Southwest, T-Mobile was considerably stronger in achieving a connection on the first try and in encountering the least amount of static.

The study also noted that nationally, T-Mobile rated significantly better than the industry average in initial connections -- calls connected on the first try.

Previously this year, J.D. Power and Associates announced that T-Mobile ranked highest in wireless customer service performance -- for the third consecutive time -- among national wireless service providers in the 2006 Wireless Customer Care Performance StudySM.
