At command not function with RUT956

Hello Teltonika,

I have a Rut956 with last firmware on novembre 2023.

I send At command by serial RS232 from my old server to send SMS using modem controle.

BUT, I have sometime that SMS no start because my system receice from RUT956 a bad response, like " or NoService. So I connect Hyperterminal by COM on my PC and I see that from Rut956 arrive every 2 seconds ^HCSQ “NOSERVICE”, also others frames like MODE, ETC…

Can you tell me how I can set router that it not send this message and it remain stopped to lissen?

Many Thanks

Dear Corrado,
It seems to be an issue with the connectivity with the Provider. Will it be possible for you to share the system logs ? Please make sure to blur any personal information such as Public IP, device serial number etc.
