Troubleshoot Google Fi activation

This article helps with Google Fi activation issues like SIM card problems, iPhone setup, and checking self-service error codes and messages.

How to fix SIM card issues for Google Fi

  • Double-check that you have a Google Fi SIM card.
  • Make sure your device is carrier-unlocked and compatible with Google Fi.
  • If you insert your SIM card and your phone says “No SIM card,” remove the SIM. Make sure it's clean and place it on the tray correctly. Then, restart your device.
    • To restart your device, hold down the power button for 30 seconds.
  • Make sure that the tray closes completely.
  • For transfers from another carrier, insert your last SIM card. If your phone recognizes your last card but not your Google Fi SIM, your phone might be carrier-locked. Contact your last carrier for more information.

How to check self-service error codes & messages in Google Fi

Google Fi doesn't support your device

To use Google Fi, you need an unlocked phone that's compatible with Google Fi. Check your phone's compatibility.

If you bought your Google Fi phone through Google Fi or the Google Store, your device is unlocked.

If you brought your own device to Google Fi, contact your carrier to make sure your phone is unlocked.

Make sure you don't owe any payments on your device. Your carrier may also have you take other steps to unlock your device.

Your Google Fi SIM card is missing or corrupt
