5G & 4G LTE Coverage map

T-Mobile is America’s largest 5G network and covers more people and places than anyone else.  While our 5G network continues to expand, you can count on our 4G LTE network that connects 99% of Americans.

  1. Access our 5G & 4G LTE coverage map from your computer or mobile device.
  2. Enter your address or a landmark, then select Enter or choose an item in the drop-down list.
  3. View the coverage in that area. You can also do the following:
    • Select and hold to drag to move the map around.
    • Select a location to get a pop-up with detailed coverage information.
    • Use the + and - icons to zoom in or out. You can also pinch to zoom.
    • Switch off 5G at the top to learn where you're covered with 4G LTE.

If your phone has signal problems where we have coverage, use Signal issues / no service troubleshooting.

Device compatibility & frequencies

Quick tip! Easily check your phone's compatibility with our network using the IMEI Status Check. No need to compare network frequencies or device lists!

  • Find the networks a T-Mobile device supports by checking your Device tutorials "Device Specs".
    • For non-T-Mobile devices, check with the manufacturer. 
    • If you want more radio frequencies/technologies, you must upgrade to a newer device.
  • To connect to the local network, your device must support both our network frequency (band) and the technology (5G, 4G LTE, 2G).

T-Mobile network frequencies

Devices often support more frequencies than these, in order to roam on other domestic and international wireless networks. They are not needed on the T-Mobile network.
