Coverage Comparison Tool
Compare any two carriers' native (non-roaming) coverage across the United States.
Use the dropdowns at the top of the map to pick which networks to compare, and customize colors with the color pickers.
Map Usage
- Pick two carriers from the dropdowns to compare
- Click the color swatches to customize carrier colors
- Zoom close for the most detailed coverage data
- Use the search bar to compare carriers in a specific location
- Switch view modes to surface different comparisons
- Overlay: Shows distinct coverage areas of each carrier
- Winner: Colors each area by which carrier has better signal or better percent coverage
- Difference: Uses color intensity to show the magnitude of signal or coverage differences
Technical Notes
-
MVNOs share host network data: MVNOs (like Mint Mobile, Visible, Cricket) use the same towers as their host network.
Comparing two carriers on the same underlying network will show identical coverage.
-
Metrics with high zoom: Zoom in for the most detailed picture. At the highest zoom levels (smallest hexagons),
the Winner and Difference views show signal strength comparisons.
-
Metrics with low zoom: When zoomed out (larger hexagons), comparisons are generally based on
coverage percentage within each hex.
Data Sourcing
Cell coverage data 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.
