T-Mobile Scores Consistently High in Call Quality


Independent Wireless Call Quality Survey Places T-Mobile Tops in Northeast and Southeast


BELLEVUE, Washington   - 08/03/2005 — Beauty is said to be in the eye of the beholder. But when it comes to wireless service, quality is in the ear of the caller. And callers around the country have said T-Mobile consistently provides quality wireless service.

According to the J.D. Power and Associates 2005 Wireless Call Quality Performance StudySM released today, T-Mobile tied for top honors in the Northeast and Southeast regions.

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

The showing was particularly strong in the Southeast, where T-Mobile received high marks for producing calls with fewer initial connection problems and for having few dropped or disconnected calls.

"In an effort to continuously improve service quality, we're offering even more reliable wireless devices, expanding coverage in our core network footprint with the addition of new cell sites and expanding geographically with rural roaming agreements," said Neville Ray, senior vice president for engineering operations for T-Mobile USA, Inc. "A evidenced by our strong showing in the Southeast region, as well as nationally, our efforts around eliminating dropped calls and enhancing call quality are beginning to pay off."

Integral to T-Mobile's strong showing in the Wireless Call Quality Performance Study is the company's Personal Coverage Check (PCC). The T-Mobile PCC allows customers to input a street address, intersection, or other variables to view T-Mobile's network coverage in a specific area. T-Mobile believes that consumers should have an accurate understanding of network coverage available in the places they go before they make a commitment to a carrier.

Previously this year, J.D. Power and Associates announced T-Mobile ranked highest among national wireless service providers in both the 2005 Wireless Customer Care Performance StudySM and the 2005 Wireless Business Customer Satisfaction Index Study.

The 2005 J.D. Power and Associates Wireless Call Quality Performance StudySM is based on call diaries from 22,730 wireless customers. More information about the J.D. Power and Associates study can be found at www.jdpower.com.
