What is the Coverage Report Map?
The Coverage Report Map provides detailed reports on cellular coverage and performance in every state, county, city, and ZIP code.
Each report is generated using publicly available FCC coverage data and our crowdsourced speed test data.
- Percentage Covered: See how much coverage each carrier has in an area, broken down by none, poor, good, great, and excellent.
- Weighted Median: Weighted median reports eliminate outlier speed tests to uncover true typical performance.
- Speed Distribution: Compare bottom, median, and top performance percentiles for each carrier at a glance.
