TL;DR

Latest crowdsourced reports from Ookla and Opensignal establish T-Mobile as the fastest and the most reliable major network in the US.

AT&T posted the highest growth in terms of download and upload speeds.

Verizon dominated with the widest network coverage in the US.

Telecom industry analysis firms Opensignal and Ookla have released their half-yearly reports detailing the performance of various carriers across the US, and there’s a clear winner. Both reports once again hail “the un-carrier” T-Mobile as the leader across various performance parameters based on crowdsourced data.

Ookla held T-Mobile as the “Best Mobile Network overall,” offering the fastest median download speeds, including 314.38 Mbps on 5G and 275.55 Mbps across different network protocols. Verizon was second in both categories after T-Mobile. T-Mobile also dominated multiple categories in Ookla’s previous half-yearly report, with the fastest download speeds in a similar fashion.
