Got a question? We have the answer!

How do I know if I have coverage in my area?

Check our GSM Coverage Map to verify service in your area.
The icons in green will show the expected coverage in that location (outdoors, indoor residential, etc.) for certain device types.
  • Outdoor
  • In Vehicle
  • Indoor Residential
  • Indoor Commercial
Enter multiple addresses/ZIP codes to check all the areas where you live work and play.
If you intend to travel, you should check the destination coverage before setting off.

If you are interested in using the service abroad, check our international service options: Wi-Fi Calling & International Roaming.
