Speed Test Map

A crowdsourced map of cellular performance data.

What is the Speed Test Map?

The Speed Test Map is a crowdsourced map of cellular data speeds.

Currently, the map is only available in the U.S. We plan on expanding the map to other countries before the end of the year.

The Speed Tes Map shows cellular data speeds on AT&T, T-Mobile, Verizon, Dish Wireless, and UScellular.

The Speed Test Map shows download speeds, upload speeds, and latency for all carriers.

Users contribute to the map by uploading speed tests. Tests can be run using the free Coverage Map app, or by other third-party apps such as SpeedSmart.

Speed tests that are uploaded to CoverageMap.com are processed in real-time and show up on the Speed Test Map as hexagons.

Clicking on a hexagon gives you more information about the performance reported in that area.

You can see peak speeds, average speeds, median speeds, and compare performance between the different carriers.

Clicking on a square reveals more information about performance in that area.

You can use powerful filters and helpful color options to customize the Speed Test Map to meet your needs.

Powerful Filters

Filter by carrier, technology, and data speeds.

Filter by Carrier

See maps for Verizon, AT&T, T-Mobile, UScellular, and Dish.

Toggling between the different carriers is a great way to see how they compare in terms of coverage and data speeds.

Network technology filter

Filter by Network Technology

See coverage areas for LTE, 5G, and Standalone 5G. Great for tracking 5G network deployments and checking 5G availability in your area.

Filter by Data Speeds

Only show hexagons that meet certain thresholds for download or upload speeds.

Ideal for finding areas that have mid-band or mmWave 5G deployed.

Or for simply finding a spot with speeds that are fast enough to get work done.

Three Helpful Color Options

Style the map in a way that's most helpful to you.

Default color profile on the Speed Test map


The default view color-codes the map to match the carrier you have selected. There are four color tiers for the hexagons. The darker colors indicate better performance.

The Heat Map color view adds more detail to the map. Instead of four color tiers, there are now nine color tiers. Dark red indicates areas with poor performance. Dark green shows areas with excellent performance.

Best Carrier color profile on the Speed Test map

Best Carrier

The Best Carrier view color-codes the hexagons to match the carrier with the best performance in a given hexagon.

Unique to CoverageMap.com, the Best Carrier view makes it easy to see what carrier has the best performance in any given area.
