I am trying to get libmbim working for the first time and have a couple of
issues. I installed 1.24. and am using a new Cinterion modem. I can see
that it is enumerated, but without any interface to send AT commands:

Is there perhaps a different driver I need?
Apart from this I am trying to create a data connection with mbimcli but am
getting registration state denied. When I check the signal strength I am
getting these 99 values, these indicate some kind or error? I have verified
that the sim works with libqmi/sierra modem. Anything else I can check?
mbimcli -p -d /dev/cdc-wdm4 --query-registration-state
