Now let's set up our new digital SIM card. The Just eSIM website has detailed instructions with screenshots for iOS and Android. Here's the general overview:
- In the web app under "My eSIMs" section, you'll see a QR code with settings. It was also sent to your email.
- If you have iOS 17.4 or newer, the process is super simple: scan this settings QR code, tap "Install eSIM" — and everything happens automatically.
- On Android and older iOS versions, you also scan the QR code, but then take a few steps in settings.
- Now your eSIM is ready to use.
If your device doesn't recognize QR codes from its own screen, you have two options: scan the QR code from another device's screen or enter the settings manually. The settings are written next to the QR code. Where to enter them is shown in the instructions.
