**Editor's Note: Which is America's top wireless network? Click here to see what we discovered.**
AT&T, which just last year passed Verizon in J.D. Power's customer-service rankings for the first time in years, better watch its back.
In its latest U.S. Wireless Customer Care Full-Service study results, released this week, the market-research company gave AT&T a score of 793 points out of 1,000. Verizon Wireless was second among the "big four" with 788 points. The average score among these "full service" companies was 782.
T-Mobile still has some work to do, but the Bellevue, Wash.-based carrier made noticeable gains, leapfrogging way ahead of Sprint for third place, with 778 points. The company has seen steady improvements in subscriber gains since doing away with postpaid contracts for new customers several months ago. No doubt that's a factor in its customer-care score improvements as well. Sprint is way behind its rivals, tallying just 757 points on J.D. Power's scale.
