How does eSIM work?
An eSIM works just like a traditional SIM card – it connects you to a local carrier's mobile network. The difference is that the profile is delivered electronically, without shipping or plastic. After purchase, you receive a QR code by email and scan it in your phone settings.

How to Install eSIM – Step by Step
Buy your eSIM
Choose your destination and data plan. After payment, you'll receive an email with a QR code within a few minutes.
Scan the QR code

Enable the eSIM before departure or after arriving in your destination country. Data works as soon as you connect to a local network.
eSIM vs. Roaming – What You Need to Know
EU roaming is free, but outside Europe costs can skyrocket – sometimes tens of euros per MB. An eSIM is a cheaper alternative: you buy a local data plan at a fair price and browse worry-free. The eSIM works alongside your home SIM – calls and texts still work normally while your eSIM handles the data.
Is eSIM Safe?
Yes. eSIM is a standard developed by the GSMA – the organisation that oversees mobile network security worldwide. eSIM data is stored in an encrypted chip built into your phone. Activation uses an encrypted protocol and the QR code is single-use. Unlike a physical SIM, an eSIM cannot be lost or stolen.
