What is eSIM?

An eSIM (embedded SIM) is a digital SIM card permanently integrated into your device. Instead of a physical card, you activate connectivity by scanning a QR code. For European travel, one eSIM plan covers 30+ countries.

Key Benefits for European Travel

  • ✓ No physical SIM to buy or insert at each destination
  • ✓ Activate before you leave home
  • ✓ One plan covers all of Europe
  • ✓ Keep your home number active via Dual SIM

How eSIM Works

Your device contains an eUICC (embedded Universal Integrated Circuit Card) — a secure chip that stores connectivity profiles. When you scan a QR code, your phone downloads an encrypted profile from the provider's server to this chip.

With Dual SIM, your phone runs both your home SIM and the eSIM simultaneously. Your home SIM handles calls and SMS; the eSIM handles data.

Step-by-Step Activation

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

Choosing a Plan

Country Coverage

Verify every destination is listed. "Europe" can mean different things to different providers.

Data Allowance

Leisure: 10–15 GB. Remote work: 20–30 GB. Heavy hotspot: unlimited.

Network Partners

Named major carriers = better quality and transparency.

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. See our Countries page for detailed data.

Travel Tips

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

Keep your home SIM active in Dual SIM mode for calls and SMS.

Save your QR code in email, cloud storage, and as a 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. Try manually selecting a different network operator.

QR code won't scan

Display on separate screen. Use SIM settings scanner. Ensure active internet connection.
