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.

Step-by-Step Activation

1

Purchase a Plan

Buy a European eSIM plan online. You'll receive a QR code by email immediately.

2

Open SIM Settings

iPhone: Settings → Cellular → Add eSIM. Android: Settings → Network & Internet → SIMs → Add SIM.

3

Scan QR Code

Display QR on a separate screen. Scan through SIM settings. Requires internet connection.

4

Enable & Configure

Set eSIM as data SIM. Enable data roaming. You're ready to travel!

Choosing a 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 information, see our Countries page.

Travel Tips

Activate before you travel — you need internet to download the profile.

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.
