How do I activate an eSIM?

  2. There are also several downloadable apps which help you choose a plan best suited to you and take you through the steps of activating the SIM.
  3. Or your network provider can create a QR code for you to scan using your phone’s camera. For iPhone users, a ‘Mobile Data Plan Detected’ notification will appear, you should click ‘continue’ and then tap ‘add mobile data plan’. You may be asked to enter a confirmation code, this will be the number your network provider gave you.

Extra information

It’s important to note that if you usually swap your physical SIM card between various devices, an eSIM may not be as straightforward. You will need to go through the activation process each time you wish to swap the eSIM. This makes the process a little more complicated than just switching the physical SIM.
