Mobile analytics firm RootMetrics drove 217,758 miles, visited 6356 indoor locations and took 4.6 million samples in an effort to determine which of the major U.S. carriers offers the best service. The testing included measurements of calls, texts and data and sought to find the most reliable and fastest pipeline. According to the study, it was a two horse race between Verizon and AT&T with T-Mobile and Sprint lagging far behind. The overall scoring placed Verizon on top (89.6 points) with AT&T close behind (86.2). Sprint (68.2) and T-Mobile (64.3) finished third and fourth respectively.
Verizon took the top spots in reliability, data, calls and text. The only category that it did not win was the one for speed. That category was won by AT&T with a score of 88.7 compared to Big Red's 88.5. Speed was also the only category where T-Mobile surpassed Sprint.
The testing was done in the second half of last year, and you can view all of the results in the slideshow below.
