Now that you've set up your Google Fi eSIM, you can use it in conjunction with the physical SIM card you received from Google Fi and switch between networks as you need to.

How to use two Google Fi SIMs on your Pixel phone

If you purchase a Pixel phone directly from Google Fi, it will come with a physical SIM card. Upon activation, that physical SIM will work in parallel with the built-in eSIM to find you the best possible wireless signal. Note that removing the physical Fi SIM will cause your phone to lose service.

If you purchase a Pixel unlocked, and add a physical Fi SIM after you activate your Fi eSIM, follow the steps below to ensure everything works together as intended.

  1. Remove the physical SIM card from the phone.
  2. Open the Settings app.
  3. Tap Network & internet.
  4. Tap Mobile Networks.
  5. Tap Google Fi.
  6. Tap Erase.

  3. Follow the instructions in the app to activate.
