An eSIM (embedded SIM) is a programmable SIM card permanently integrated into a device's hardware. The GSMA standardized eSIM technology in 2016 via the SGP.22 specification, enabling remote SIM provisioning — the ability to download and manage carrier profiles without physical card swapping.
For travelers, this means purchasing a regional European plan online and downloading it via QR code before departure. A single plan can cover 30+ countries, with automatic network selection at each border crossing.
The eUICC (embedded Universal Integrated Circuit Card) chip stores multiple profiles simultaneously, enabling Dual SIM functionality — using a home SIM for calls while the travel eSIM handles data.
