eSIM for European Travel
What Is eSIM?
An eSIM is a digital SIM card built into your phone. Carrier profiles are downloaded via QR code — no physical card needed. Governed by GSMA SGP.22, supported by all major devices since 2018.
For European travelers, eSIM eliminates the friction of physical SIM management. Buy online, scan QR, arrive connected.
How It Works
The eUICC chip stores carrier profiles in isolated secure containers. Each profile is cryptographically bound to your device's unique EID. The SM-DP+ server delivers encrypted profiles during activation.
