How an eSIM works in your phone
An eSIM is a tiny built-in chip inside your device that replaces the need for a physical SIM card. It can store multiple eSIM profiles, each with its own number and mobile plan, letting you switch between them just like swapping SIM cards — only without the plastic.
Set up your eSIM
After registering for your eSIM you’ll receive a QR code – simply scan it to start set up. Detailed instructions for your specific device can be found in our device guides
Step 1 - Scan QR code
Scan the QR code you've just received.
Step 2 - Select eSIM
If you have a SIM already installed in your phone, you might be asked to select which SIM to use for your data and default number. Select the Vodafone eSIM for both - you can change this anytime.
Congratulations - Your eSIM is now set up!
You can now enjoy our reliable, award-winning network.
