Consumer Cellular runs over AT&T's network. In the past, Consumer Cellular also offered T-Mobile-based service, but the carrier now operates only over AT&T's network.
Cell coverage data used in the Consumer Cellular 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.
