Three takeaways from Ookla’s H2 2025 Connectivity Report

Ookla’s H2 2025 Connectivity Assessment, a 40-page performance report on U.S. mobile networks, again ranks T-Mobile US as the country’s best mobile network. The operator continues to lead on core metrics such as speed and coverage, reinforcing a pattern seen in earlier testing cycles.

The report highlights three main points: T-Mobile holds the top overall network position; the competitive gap between carriers is shaped by how they deploy spectrum and 5G; and measured user experience still varies by location despite national rankings. Ookla’s findings underline that while one operator can claim the overall crown, network quality depends heavily on where people live and use their phones.
