We recommend installing your eSIM before you start your trip.
You can complete the first part of the setup (installing the eSIM profile) comfortably at home, so you don’t have to worry about it while traveling.
Important: You should only activate your purchased plan during the flight or after arriving at your destination.
This is because your eSIM validity period starts as soon as the plan is activated.
You can find the full installation guide for your eSIM here.
