A major study of phone call quality among the four national wireless carriers and top regional carriers was not flattering for AT&T.
The study, released Thursday by J.D. Power and Associates, showed that AT&T, the second-largest carrier, did not rank first in any of six geographical regions.
AT&T ranked fourth in Northeast, North Central, and West, third in the Southeast, and second in Mid-Atlantic and North Central.
Verizon Wireless was the top national carrier in every region. U.S. Cellular beat Verizon in North Central.
AT&T would be first to tell you that its service needs improvement. That's one of its main rationale for justifying its $39 billion purchase of T-Mobile.
