Providing your Google device is newer or the same as the Google Pixel 2, (only phones bought with Google Fi service) then your phone should be compatible with an eSIM.
If you would like to check this, you can do so by following these steps:
1. Go into Settings.
2. Scroll down until you see the section "About Phone".
3. At the top, you should see "Device Name". Here you can see which phone model you have.
If you are struggling with deciding if your model is compatible with our eSIMS, please have a look at our list of Google Compatible Devices.
