Hi @tom !
Thank you for your response, the issue was solved by deactivating this service.

Thank you so much

Hi

we are trying to set up the 5G quectel modem, we tried with different mobile networks and different SIM cards.
We are getting a disconnection from the mobile network approximately every minute, sometimes a bit more.

Looking into the journalctl we can see the following pattern every few seconds: carrier lost and the modem connects again
We are thinking if the config-wwan0.sh could be the reason... but any other ideas are appreciated
