When your Viettel eSIM displays the “No Service” error, it can be caused by several factors — such as device incompatibility, incorrect eSIM installation, or temporary disruptions in the mobile network. Viettel recommends checking your phone’s eSIM settings, ensuring the eSIM profile is active, and restarting your device to refresh the connection.
If these steps do not fix the issue, you can re-scan the QR code or contact Viettel’s customer support through the MyViettel app or the hotline 18008098 for further assistance. This ensures your eSIM remains active and connected without interruption.
