The carrier’s median 5G download speed was 193Mbps, well ahead of Verizon’s 119Mbps in second place, and more than twice AT&T’s 81Mbps figure. T-Mobile, however, led the pack by a considerable distance in terms of 5G performance, the report found. The most consistent throughput performance was also tightly contested among the big three carriers, with 84.4% of tests on T-Mobile’s network reporting at least 5Mbps download speeds, compared to 79.6% and 79.4% for Verizon and AT&T, respectively. Multiserver latency-which measures the latency users can expect to experience when the network isn’t under particularly heavy load conditions-was topped by Verizon in the mobile broadband category, at a median of 59ms, compared to 60ms for T-Mobile and 61ms for AT&T.

The figures were gathered via Ookla’s online Speedtest website that can test users' internet upload and download speeds, latency, and more. T-Mobile retained its place as the consensus fastest mobile data provider in the US, posting a median download speed of 116Mbps and outstripping Verizon and AT&T by a roughly two-fold margin in the latest market analysis report from network analysis firm Ookla.Īmong fixed-broadband services Ookla's third-quarter testing found that Spectrum beat Cox and Xfinity for the top spot with a median download speed of 211Mbps.
