Complete the checks first
The installation step is easy to rush; the compatibility and activation rules are what prevent avoidable failure.
- Confirm the phone is eSIM-ready and carrier-unlocked.
- Check the exact model and sales region.
- Read whether validity starts on install or first connection.
- Save the QR code and provider help page offline.
Leave a clean handoff for arrival
Label the travel line clearly, keep the home line available for verification, and write down which line should carry mobile data after landing.
Do one low-risk test before departure without changing several SIM settings at once.
