The installation of the Link Advanced is not successful, you are blocked, because you encounter the message: "No GSM mobile network found".
The GSM installation is confronted with the reception of a non-existent signal. Check that the installation is done in one of the countries supported by the GSM network coverage.
If the country is still on the list, it is likely that you are in a white area.
Without GSM network coverage, installation and operation must then be done via Wi-Fi.
