T-Mobile USA has matched Verizon Wireless in a series of crowdsourced speed tests but still trails both Verizon and AT&T in overall network coverage.
The findings come from the company OpenSignal and are based on 377 million data samples from 182,000 users of the OpenSignal Android and iOS apps during the last three months of 2015.
"Verizon is still the operator to beat when it comes to network reliability, but T-Mobile is squaring off against the super-carrier in download speed," OpenSignal wrote. "Nationally both operators are averaging 4G [LTE] connections of 12Mbps, and in a speed comparison in the 11 largest US cities, T-Mobile just barely edged out Verizon. AT&T and Sprint hardly even factored in the contest."
