It takes under a minute and should be done before your trip, on Wi-Fi. Installing does not start the plan.
Before you start
- Connect the iPhone to Wi-Fi.
- Have the QR code open on another screen.
- Make sure the iPhone is not carrier locked. A locked phone will not install another carrier eSIM.
Step by step
- Open Settings and tap Cellular or Mobile Data.
- Tap Add eSIM.
- Choose Use QR Code and point the camera at it.
- Name the plan, for example after the destination.
- Set your usual line as Default Line, and the new plan as Cellular Data.
When you land
- Turn data roaming on for the Mondial Chips plan only.
- Keep mobile data off on your home line so it does not bill roaming.
- If it takes long to connect, toggle airplane mode once.
