Before we delve into the setup process, let’s briefly explain what Google Fi eSIM is all about. Google Fi is a unique mobile virtual network operator (MVNO) service that leverages multiple carrier networks to provide you with the best possible coverage and speed. The eSIM, or embedded SIM, is a digital SIM card that eliminates the need for a physical one, making it easier to switch carriers and activate your phone.

The release of the iPhone 15 and 15 Pro has brought with it exciting advancements, including support for eSIM technology. This means you can now enjoy the convenience and flexibility of using Google Fi without needing a physical SIM card. In this guide, we’ll walk you through the step-by-step process of setting up Google Fi eSIM on your iPhone 15 or 15 Pro.

How to Set Up Google Fi eSIM on iPhone 15 and 15 Pro

Prepare a Second Device
You will need a second device, such as a laptop or your previous phone, connected to Wi-Fi.
Visit the Google Fi Website
On your second device, open a web browser and go to “fi.google.com/ios/quicksetup.”
Scan the QR Code
Follow the on-screen instructions to scan the QR code displayed on the Google Fi website. This will initiate the eSIM activation process.

The issue people are facing today in addition to Fi customer support not having updated instructions is when transferring service from an old iPhone to a new model. They may encounter a message that says “Your SIM is Not Supported”.

To get around that, tap “Other Options” to “reveal the QR code and complete eSIM activation.”

Google also advises that you first delete the old iPhone’s eSIM.

Go to Settings > Cellular > Cellular Data Network
