WHAT IS eSIM?

An eSIM (embedded SIM) is a programmable SIM card permanently integrated into your device's hardware. Unlike physical SIM cards, eSIM profiles are downloaded digitally via QR code — governed by the GSMA SGP.22 specification.

The eUICC (embedded Universal Integrated Circuit Card) chip stores multiple carrier profiles in isolated secure containers. Each profile is cryptographically bound to your device's unique EID, preventing cloning.

For European travelers, eSIM eliminates the friction of physical SIM management: no airport kiosks, no carrier stores, no language barriers. Purchase a plan online, scan a QR code, connect in minutes.

COMMON QUERIES

Q: What devices support eSIM?
A: iPhone XS (2018)+, Samsung Galaxy S20+, Google Pixel 3+. Verify: Settings → About → EID (32-digit number confirms eSIM hardware).
Q: Does eSIM cover all EU countries?
A: Regional EU plans cover all 27 member states. EU RLAH regulation ensures domestic rates. Switzerland/UK/Norway outside EU — verify per plan.
Q: Is eSIM secure?
A: Yes. Profiles cryptographically bound to device EID. eUICC achieves EAL4+ certification. GSMA SGP.22 mutual authentication prevents MITM attacks.
Q: Troubleshoot: No service after activation?
A: CHECK_LIST: [1] eSIM enabled [2] Data Roaming ON [3] Airplane Mode toggle [4] Manual network select [5] Device restart [6] Contact provider
