What is eSIM?
An eSIM (embedded SIM) is a digital SIM card built directly into your phone. Instead of inserting a physical card, you download a connectivity profile by scanning a QR code. For European travel, one eSIM plan can cover 30+ countries.
Why eSIM for European Travel?
- ✓ No physical SIM to buy or insert
- ✓ Activate before you leave home
- ✓ One plan for all of Europe
- ✓ Keep your home number with Dual SIM
How eSIM Works
Your phone contains a tiny chip called an eUICC (embedded Universal Integrated Circuit Card). When you scan a QR code, your phone connects to the provider's server and downloads your connectivity profile to this chip. The profile contains everything needed to connect to local networks in each country.
With Dual SIM, your phone can have both your home SIM and the eSIM active simultaneously. Use your home SIM for calls and SMS, and the eSIM for data.

Choosing a Plan

Verify every destination is included. Some plans exclude popular countries.
Data Allowance

Keep your home SIM active in Dual SIM mode for calls and SMS.
Save your QR code in multiple places — email, cloud, printed backup.
Enable data roaming before crossing borders.
Troubleshooting
No connection after activation
Set eSIM as active data SIM. Enable data roaming. Toggle airplane mode. Wait 2–3 minutes.
Slow speeds
Check remaining data. Manually select a different network operator.
QR code won't scan
Display on separate screen. Use SIM settings scanner, not a QR app. Ensure internet connection.
