What Is eSIM?

An eSIM is a digital SIM card built into your phone. You download a carrier plan via QR code instead of inserting a physical card. For travelers, this is transformative: buy a plan from home, arrive already connected.

Your device can store multiple eSIM profiles simultaneously. Travel from Portugal to Germany to Austria — switch plans with a tap, no store visits required.

Travel Tips

Install before departure

Set up at home over reliable Wi-Fi. Airport Wi-Fi is often unreliable.

Enable Data Roaming

Without this, your device won't use eSIM data abroad.

Save your QR code

Screenshot it as backup in case reinstallation is needed.

Check validity period

Activation-based validity is more flexible than purchase-date validity.

Troubleshooting

No data after activation

Check: eSIM enabled, Data Roaming on, toggle Airplane Mode, manual network selection, restart.

Slow speeds

Check data allowance. Verify LTE/5G in network settings.

Activation failed

Verify device is unlocked. Retry on stable Wi-Fi. Use manual code.
