For travelers crossing multiple European borders, this is transformative. Instead of hunting for local SIM vendors in unfamiliar cities, you can activate a data plan before your flight even lands. The technology is now supported by most flagship smartphones released after 2019.

The process is simpler than most travelers expect. Here's what happens from purchase to your first connected moment abroad.
Verify your device supports eSIM and is unlocked for international use. Most phones from 2019 onward qualify.
Select a data plan suited to your travel duration and countries. Regional European plans often cover 30+ countries.
After purchase, you receive a QR code by email. Scan it in your phone's cellular settings to download the profile.
Enable the eSIM when you arrive. Your device automatically connects to the best available local network.
Arrive with data already active. Skip the SIM kiosk queues and navigate your destination from the moment you land — maps, transport apps, and messaging all ready to go.
On the Eurostar or a night train from Vienna to Zurich, a regional eSIM plan keeps you connected as networks change automatically at each border crossing.
Whether you're in a Lisbon co-working space or a Prague café, reliable mobile data means you're never dependent on uncertain public Wi-Fi for client calls or deadlines.

Select modelsYes. Most modern smartphones support Dual SIM functionality, meaning you can have your home SIM (physical or eSIM) active for calls and texts while using a separate travel eSIM for data. Your home number remains reachable throughout your trip.
Yes, you need an internet connection to download the eSIM profile initially. This can be done at home before you travel, using your home Wi-Fi. Once activated, the eSIM works independently of Wi-Fi.
Carrier-locked phones may not accept eSIM profiles from other providers. If you purchased your phone through a carrier on a contract, contact them to request an unlock before traveling internationally. Most carriers will unlock phones after the contract period ends.
Most devices can store between 5 and 20 eSIM profiles, though typically only one can be active at a time (alongside a physical SIM). iPhones running iOS 16 or later support up to 8 active eSIMs simultaneously.
