Opensignal has put out its January 2025 mobile network rankings based on its widely-crowdsourced performance data. In many categories, the big three US carrier networks performed similarly, with scores differing by just a few percentage points. But in several key categories, T-Mobile pulled far ahead, while Verizon performed notably better in one key category. In "Overall Experience" (including 4G and 5G), T-Mobile scored almost triple the other networks in download speed, and around double in upload speed. Focusing on just 5G, T-Mobile performed around 65% better on download speed, while for upload speed, Verizon performed 11% better than T-Mobile and 48% better than AT&T. On coverage, all three carriers were a near-tie when considering both 4G and 5G. But looking at just 5G, T-Mobile had a commanding lead in both "Coverage Experience" and "Availability". Opensignal found that T-Mobile customers with a 5G plan were able to connect to the 5G network about 72% of the time, while AT&T customers connected to 5G around 15% of the time, and for Verizon it was just under 11%. Opensignal collects its data from the phones of people who have the Opensignal app installed on their phone.
