4-step setup on iPhone and Android before you fly

Check that your phone is unlocked and supports eSIM by dialling *#06# — if an EID number appears on screen, your phone has an eSIM chip.

Install the profile over home Wi-Fi the day before departure. Keep the travel eSIM line switched off until you land, then enable it for Mobile Data with Data Roaming turned on for the travel eSIM (and Data Roaming turned off on your home SIM).
