Google Fi Coverage Map

Google Fi runs over T-Mobile's network. Additional coverage may sometimes be available through T-Mobile's roaming partners, but its unclear exactly what roaming access Google Fi subscribers have access to. Roaming coverage is not shown in the map below.

Google Fi previously offered a unique (non-roaming) technology for switching between the networks offered by T-Mobile, Sprint, and US Cellular. Google Fi no longer uses that novel technology for network switching.

Using the Coverage Map

Data Sourcing

Cell coverage data used in the Google Fi 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.
