Consumer Technology Guide
A complete, practical guide to eSIM technology for European travel.
An eSIM is a digital SIM card built into your device. Instead of inserting a physical card, you download a carrier profile by scanning a QR code. The GSMA standardized the technology, and it's now supported by virtually every flagship phone released since 2019.
For European travelers, the key benefit is simple: one pan-European plan covers 30+ countries. No more buying local SIM cards at each destination.
Buy plan, receive QR code by email.
Settings → Cellular → Add eSIM (iPhone) or SIM Manager (Android).
Profile downloads in 5–10 minutes on Wi-Fi.
Set eSIM as data line, enable roaming. Done.
