My data isn’t working

For U.S. locations, check the coverage map. If you’re using your phone outside the U.S., check the 120+ supported countries where you can use Google Fi.

If we’ve got coverage in your location: Try to move to a nearby spot where you’ve got a signal. If you’re inside a building or underground, step outside, as buildings can sometimes block signals. If that doesn’t work, proceed with the next steps.

If we don’t have coverage in your location: Try connecting to Wi-Fi.

Tip: If you and other Google Fi users experience connectivity issues only at a specific address and not at other locations, it’s likely a coverage issue. Use Wi-Fi at that location.

To check your internet connection, open another website on your phone like android.com. If it works, the issue can be with the specific website or app you’re trying to use.

If another website doesn’t work, continue on to the next steps.
