What Is an eSIM QR Code?

An eSIM QR Code is a unique code provided after purchasing an eSIM plan. When scanned with your phone, your device automatically downloads the eSIM profile and adds it to your cellular settings.

Unlike a traditional SIM card, there is nothing to insert into your phone. Everything happens directly in your device settings while connected to Wi-Fi.

Important: most eSIM QR Codes are single-use. Keep your installation email until your eSIM is fully working.

1. Buy Your eSIM

Choose your destination, data allowance and plan duration.

2. Receive Your QR Code

Your eSIM and installation instructions are delivered by email.

3. Scan the Code

Your phone downloads the eSIM profile and adds it to your device.

4. Activate Mobile Data

At your destination, select the eSIM for mobile data and enable data roaming on that eSIM.
