What is eSIM?
eSIM is a digital mobile profile you download to your phone — usually via QR code. Instead of swapping a plastic chip, you add a second data line for travel while keeping your main number active for calls and WhatsApp.
Why use eSIM for travel?
- No expensive roaming — fixed EUR price per GB
- Activate before you fly — install the profile 1–2 days before departure
- No airport SIM queues — skip local SIM shops at arrival
- Dual SIM — keep your home number + use eSIM for data
