4G LTE · 38 Mbps · eSIM active
An eSIM (embedded Subscriber Identity Module) is a digital SIM card built directly into your smartphone, tablet, or laptop. Unlike a traditional physical SIM card, an eSIM is programmable — you download carrier profiles digitally, switching between networks without ever touching a physical card.
For European travelers, this means purchasing a regional data plan before departure, scanning a QR code, and arriving connected in 30+ countries without visiting a single carrier store. The eSIM profile handles automatic network selection at every border crossing.
The technology is standardized by the GSMA (Global System for Mobile Communications Association) and supported by all major device manufacturers since 2018.
