How to install an eSIM on iPhone
An eSIM is installed without a physical card: once you receive the QR code or activation details, you add the plan in your phone settings. Connect to the internet (for example over Wi‑Fi) before installing, and do not delete the plan until your trip is over.
- Open Settings → Mobile Service (or Cellular) → Add eSIM.
- Choose “Use QR Code” and scan the code you received (or enter the details manually).
- Give the plan a label such as “Travel” and select it for mobile data.
- When you arrive at your destination, turn on Data Roaming for this plan.
