Credit: Edgar Cervantes / Android AuthorityAT&T was named best network by Rootmetrics, while T-Mobile claims the Speedtest crown, showing there’s no single “best” carrier for everyone.Different awards use different methods, so the right carrier depends on your priorities and where you live.Local coverage varies a lot, so always check how each carrier performs in your area before deciding.Recently, Rootmetrics awarded AT&T as the best network for the first half of 2025. This might sound strange if you’ve seen T-Mobile’s latest ads, which claim that after years of Verizon being on top, the Uncarrier now holds the crown. So which is it, AT&T or T-Mobile? And where does Verizon stand in all of this? The truth is, there’s really no such thing as “the best” network; the right choice depends on your needs and location.First, it helps to understand there’s more than one major report carriers use to declare themselves the best. T-Mobile’s results come from the Ookla Speedtest Awards, while AT&T’s victory is thanks to Rootmetrics. These two testing systems use different methods. Ookla’s Speedtest Awards rely mostly on user-initiated test results, while Rootmetrics combines crowdsourced data with independent, on-the-ground testing, which some people consider more thorough.
