Uh-oh: It looks like T-Mobile CEO John Legere has a new reason to boast about his “Un-carrier.” J.D. Power’s newest Wireless Customer Care Full-Service Performance Study shows that “T-Mobile ranks highest among wireless full-service carriers” in customer care, which means T-Mobile customers are the happiest about the customer service they receive.

Legere was predictably not shy about touting this accomplishment.

“Let me tell you, our Care teams have earned every one of those top JD Power honors,” he said on T-Mobile’s official blog. “They crushed it. All we really did was get out of their way. At T-Mobile, our awesome Customer Care team has been one of the biggest keys to our success.”

T-Mobile also recently ranked first among the major wireless carriers in Consumer Reports’ latest customer satisfaction rankings, although the publication also found that people who subscribed to smaller wireless carriers were happier with their service than customers who subscribed to major wireless carriers.

Among prepaid carriers, J.D. Power said that Sprint subsidiary Virgin Mobile had the highest customer care ratings. You can check out J.D. Power’s full press release at this link.
