Mobile Performance Race Intensifies in Dallas

BELLEVUE, Wash., Nov. 19, 2015 (GLOBE NEWSWIRE) -- Today RootMetrics®, the standard for independent mobile performance testing, is out with its latest rankings which revealed all four mobile carriers display solid mobile service throughout the Dallas metro area. According to the 2nd Half 2015 Dallas Metro RootScore Report, AT &T and Verizon shared first place when it came to overall mobile performance and Sprint and T-Mobile were close behind, with only about two points separating the first-place winners and last place.

"AT &T and Verizon topped our rankings when it came to overall mobile performance in Dallas, but the competition is intensifying," said Julie Dey, RootMetrics vice president. "With close rankings across the board, and particularly high scores in overall mobile performance, network reliability, data, call, and text performance, mobile consumers in are the real winners."
