Hi, I'm using Thinkpad T480 with a sim-card module.
Installed ModemManager, setup the sim-card provider and cdc-wdm0 interface is working fine and I can be able to access internet without any issue.
After quite sometime cdc-wdm0 suddenly shuts down and cleans up the port 'net/wwan0', and I have to reset the interface with nmcli.
Here is the ModemManager logs when the interface shuts down:

Before you ask I have checked the module hardware and it is ok.
I also had Fedora before and this issue occurred on it as well but it was not that frequent, maybe in 2/3 hours this event occurred on Fedora, but in Arch it will occur in 30/40 minutes!
If you need any other information please ask. Thanks a lot.
