Scanning a code from the provider to add the eSIM profile.
Many providers send a QR code after purchase. You scan it in the phone's eSIM settings and the profile downloads. Others install the profile directly from their app.
The code belongs to one profile, so keep it private and do not share it with others.
What to check
- Install over Wi-Fi
- Keep the code until the trip is over, in case you must reinstall
