    Check the connection

    The status bar should show a local network name and the 4G/5G icon. Restart the phone once if needed.

Troubleshooting

The QR code says “invalid”

Each QR code can be used only once. If the eSIM was already added it appears in the list; if it was deleted, contact support for a new code.

The eSIM is installed but there is no internet

Check that the travel line is selected for mobile data and that Settings › Mobile network › Mobile data › Data roaming is on. Toggle airplane mode on for 10 seconds, then off.

No network found

Switch network selection from automatic to manual, pick a supported operator from the list, then switch back to automatic.

I am asked for an APN

Most plans set the APN automatically. If asked, enter the APN from your email in the mobile network settings.

My main line was turned off

Both lines can stay on at the same time. Turn the main line back on in the SIM manager and keep only mobile data on the travel line.
