Who really gives you the fastest download speeds in the US? According to a
new report on America's mobile networks from OpenSignal, the answer is T-Mobile. The carrier easily took the top spot when it came to downloads on 3G (an average speed of 3.5 Mbps compared to second place AT&T’s 2.2 Mbps), and just narrowly clinched the top spot for 4G (12.3 Mbps download speeds compared to Verizon’s 12 Mbps). Both Verizon and Sprint performed pretty badly on 3G (0.7 Mbps and 0.6 Mbps respectively), while AT&T and Sprint did marginally better on 4G (7.9 Mbps and 6.6 Mbps respectively).
To keep these figures in context, the average download speed on an LTE network in the US was 9.9 Mbps — fine for loading web pages and keeping your apps ticking over, but short of the global average of 13.5 Mbps and well behind top performers like New Zealand and Singapore (average LTE speeds of 36 Mbps and 33 Mbps respectively in
last year’s report). The US does make up for this in terms of coverage, though, with subscribers getting an LTE signal 81 percent of the time — putting it in the top 10 worldwide, impressive for such a large nation.
T-Mobile was also particularly successful when it came to coverage. The carrier has previously lagged behind its rivals, but as part of CEO John Legere’s ambitious and often bombastic campaign to remake "the Uncarrier," it has improved its LTE coverage to 81 percent — up from 61 percent at the
beginning of 2014. That’s still behind AT&T (82 percent) and Verizon (86 percent), but ahead of Sprint (70 percent). Coverage in this case is based on the amount of time subscribers have an LTE signal available to them — not necessarily geographic availability.
