What is eSIM?
An eSIM (embedded SIM) is a digital SIM card built directly into your phone. Unlike a physical SIM card that you insert and remove, an eSIM is permanently soldered to your device's circuit board. You activate it by downloading a connectivity profile via QR code.
Key Benefits for Travelers
- ✓ No physical SIM to buy, insert, or lose
- ✓ Activate before you travel
- ✓ One plan covers 30+ European countries
- ✓ Keep your home number active with Dual SIM
- ✓ Instant activation — no queuing at kiosks
How eSIM Works
Your device contains an eUICC (embedded Universal Integrated Circuit Card) — a secure chip that stores eSIM profiles. When you scan a QR code, your device connects to the provider's server, authenticates, and downloads your encrypted profile.
The profile contains all the information needed to connect to the provider's network: authentication keys, network settings, and access credentials. Once installed, your device uses this profile to connect to local networks in each country you visit.
Step-by-Step Activation
Purchase a Plan
Buy a European eSIM plan online. You'll receive a QR code by email immediately after purchase.
Open SIM Settings
iPhone: Settings → Cellular → Add eSIM. Android: Settings → Network & Internet → SIMs → Add SIM.
Scan the QR Code
Display QR on a separate screen. Scan through SIM settings (not a QR app). Requires internet connection.
Enable & Configure
Set eSIM as data SIM. Enable data roaming. Your phone now uses eSIM for data.
Choosing the Right Plan
Country Coverage
Verify every destination is included. Some plans exclude popular countries.
Data Allowance
Leisure: 10–15 GB. Remote work: 20–30 GB. Heavy hotspot: unlimited.
Network Partners
Named major carriers = better quality. Avoid plans that don't disclose partners.
Hotspot Policy
Verify tethering is explicitly allowed if you need to share data.
European Coverage
Europe has excellent mobile infrastructure. 4G LTE coverage exceeds 95% of the population in most EU member states. 5G is active in all major cities. For detailed country-by-country analysis, see our Countries page.
Pro Tips

Troubleshooting
No connection after activation
Set eSIM as active data SIM. Enable data roaming. Toggle airplane mode. Wait 2–3 minutes.

Check remaining data. Manually select a different network operator in settings.
QR code won't scan
Display on separate screen. Scan through SIM settings, not a QR app. Ensure internet connection.
