Helium Mobile primarily runs over T-Mobile's network. The coverage map above captures Helium's T-Mobile-based service area.
Helium Mobile's coverage is supplemented by Wi-Fi hotspots that are part of the Helium project. A map of Wi-Fi access points can we found on Helium's website.
Cell coverage data used in the Helium 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.
