CREDO previously used Verizon's network. Its current coverage map shows T-Mobile-based coverage. This map also shows T-Mobile coverage, but some existing customers may still be on Verizon's network.
The map displays predicted outdoor signal quality. Indoor signal, congestion, and roaming coverage aren't mapped. Each can matter in practice.
Cell coverage data for CREDO Mobile comes primarily from the October 2026 release of the FCC's Broadband Data Collection program (representing networks as of June 2026), supplemented with real-world measurements from large crowdsourcing projects.
