If you can’t connect to cellular data—for example, you can't open a website or use an app while you're not on Wi-Fi—try the troubleshooting steps below to fix the issue. After each step, try visiting a website to see if the issue is fixed. You can always use the buttons below to contact a Google Fi expert.
If you're having trouble connecting to Wi-Fi, learn how to troubleshoot your Wi-Fi connection. If you didn't buy your phone from Google Fi or the Google store, check with your phone's manufacturer for details.
Tip: We recommend always connecting to Wi-Fi when it’s available to expand your coverage in places where the cellular network isn’t as strong.
Important: The ability to use data and call at the same time depends on the network you’re on. It won’t always work.
Check the coverage map for U.S. locations. If you’re using your phone outside the U.S., check the 120+ supported countries where you can use Google Fi.
If we have coverage in your location: Try going to another spot nearby where you have a signal. If you are inside a building or underground, try going outside. Buildings can block signals sometimes. If that doesn’t work, continue on to 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.Try opening a different website on your phone, like android.com, to see if you can connect to the Internet. If so, there might be an issue with the website or app you're trying to use.
If another website doesn’t work, continue on to the next steps.
