The Technology
An eSIM — embedded SIM — is a digital SIM card permanently integrated into your device. Unlike a traditional physical SIM, it requires no insertion, no plastic, and no visit to a carrier store.
You purchase a data plan online, receive a QR code, and scan it with your phone. Within minutes, you are connected to European networks — seamlessly, elegantly, effortlessly.
The dual-SIM capability means your home number remains active while your eSIM handles data. No compromises.
Built into your device's hardware permanently
Scan QR code and connect in under 5 minutes
One plan covers 30+ European countries
