Gather around, carrier fandom, we've got the latest Q4 metrics on speed, coverage, reliability, latency and 3G fallback for the big four US networks, courtesy of the OpenSignal methodology. This report has become a staple in navigating through the maze of carrier claims for coverage and download speed, and there are some movers and shakers since the H1 2016 info that came out in August.
Verizon is still slightly ahead of T-Mobile when it comes down to LTE network reliability, while AT&T is still at third place. On the average LTE speeds front, Verizon and T-Mobile are neck and neck now, a tad shy of 17 Mbps, while T-Mobile scored a tad quicker download speeds than Verizon before, so that LTE-Advanced implementation is starting to pay off for Big Red.
When it comes to 3G speeds, however, T-Mobile beats by a mile, both in speed and in latency, so even if you aren't covered by its LTE network, there would still be nice speeds to fall back on. Sprint excels in none of the categories, and AT&T is the same rich slacker. When it comes to actual coverage, that's a different story, but as for quality of the big four networks, T-Mobile and Verizon take the proverbial cake again.
