The “Un-carrier” might not have the strongest mobile network out there but it’s nonetheless done an impressive job of improving its service despite having more limited resources than Verizon and AT&T. Computerworld has posted the results of a big new survey of wireless subscribers in the United States that has found T-Mobile customers’ satisfaction with their carrier has surged over the last year.

The survey found that 54% of T-Mobile customers were satisfied with the connection availability on T-Mobile’s network, which was still well behind Verizon (69% satisfied) and AT&T (67% satisfied). However, when it comes to a connection’s reliability, the survey found that 58% of T-Mobile customers were satisfied, or just one percentage point below Verizon customers’ satisfaction with their connection liability. This is particularly impressive given that T-Mobile’s connection reliability rating in 2013 stood at just 44%.

Things look even better for T-Mobile when we turn to mobile data speeds — Computerworld writes that “T-Mobile is on top in the current survey with a 65% satisfaction rate, followed by AT&T at 62% and Verizon at 59%,” while “Sprint is far behind with only a 43% satisfaction rate, barely beating out its 39% dissatisfaction rate.”

So it sounds like T-Mobile has made huge strides in terms of network data speeds and connection reliability but still has a lot of work to do on overall connection availability.
