Trump Mobile runs over T-Mobile's network. In September 2025, the carrier's coverage page stated the following:
Our service covers 98% of America with 5G and 4G LTE coverage. No matter where you are, youβre probably within range.
Equivocation between the percent of Americans covered and the percent of America covered is common in the cellular industryβand pretty misleading. Excluding satellite service (which Trump Mobile doesn't offer), T-Mobile covers the vast majority of Americans but only about half of America by land area.
Cell coverage data used in the Trump Mobile coverage map comes primarily from the May 2025 release of the FCC's Broadband Data Collection program (representing networks as of December 2024). FCC data is supplemented by data from massive crowdsourcing efforts.
