Your first eSIM, without the mistakes
The three things first-timers get wrong, and how to avoid all of them before you buy.
Author: eSIMonline Travel Desk · Travel content desk
Quick answer
- First confirm the phone supports eSIM and is not carrier-locked.
- Install at home; do not wait until the destination airport.
Three common mistakes
- Deleting the profile before arrival because it looks inactive
- Forgetting to set the eSIM as the data line, so the home SIM roams
- Scanning the same QR on a second phone
