How it works

Install the Yesim app from the App Store (iOS) or Google Play (Android) on an eSIM-compatible smartphone.

Sign up with your email address or a third-party account (Apple/Google) then complete the basic information.

Choose the data volume and duration that match your travel needs, then confirm.

Settle your purchase via the available payment methods (cards, wallets, etc.).

Follow the app instructions to install the eSIM profile (QR code scan or direct installation from settings).

Upon arrival in the country, activate the eSIM in settings and ensure that data roaming is enabled.

⚠️ If it fails

✅ Check your phone’s eSIM compatibility, ensure a stable internet connection during installation, and follow the procedure indicated by Yesim. Contact support if the problem persists.

✅ Toggle Airplane mode on/off, verify that the Yesim eSIM is selected for mobile data and that roaming is enabled. Try restarting the device.
