💡 Good to know
- Install your eSIM before you travel, while you still have wi-fi — then just switch it on when you arrive.
- The plan activates on first connection in the destination country, so buying early costs you nothing.
- Your home number stays active — calls and texts keep coming to your physical SIM.
