  2. Click Join Fi.
  3. You will be asked to sign in to your Google account. Make sure this is your account and the one you want to use with Google Fi. You will use this account to manage your Google Fi account.

  5. Choose your phone or bring your own. If you buy your phone from Google Fi, it will come with a SIM card already. If you want to bring your phone, confirm it will work with Google Fi and order a SIM card.

  1. Download the Google Fi app from the Google Play Store. You will need an active data connection such as a Wi-Fi connection to complete the setup.
  2. Turn off your phone and insert the Google Fi SIM card. If you're using an eSIM device like the Pixel 4 series, this step will not be necessary. You still may need to remove your old carrier's SIM card to complete the setup.
  3. Turn on the phone and have some patience. Your phone will need to read the SIM card configuration, which can take a minute or two depending on your phone.
  4. Make sure you're online, preferably with a stable Wi-Fi connection.
  5. You will need to sign in to the Google account you set up earlier if it's not already on your device. You will need to confirm your billing information.
  6. Follow the app instructions to confirm your choice of plan and finish setting up your phone number. Final activation may take a few minutes.
  7. You're all set! You can review your account information in the Google Fi app.

If you have any trouble, you can contact support in the app to get assistance with your account.
