Cellcom Coverage Map

The map shows Cellcom's native coverage (coverage coming from Cellcom's own network rather than a roaming partner). Most of the coverage falls within Wisconsin.

The map reflects predicted outdoor signal quality. Indoor signal, congestion, and roaming aren't mapped. Each can matter in practice.

Data Sourcing

Cell coverage data for Cellcom comes primarily from the November 2025 release of the FCC's Broadband Data Collection program (representing networks as of June 2025), supplemented with real-world measurements from large crowdsourcing projects.
