This error seems to come from the libmbim, could you share the actual
commands you use and the logs with debug enabled?

What do you mean by "non-standard"?

If, as it seems, the modemmanager is using the MBIM protocol to communicate
with the modem, CID number should not be a problem, unless a combination of
AT + MBIM command has been used (which should be avoided, only AT commands
or only MBIM ones).

Lilkewise the first problem, could you share the actual commands used and
the debug logs? Plus - just for debugging - what's the output of the
command "AT+CGDCONT?" in this use case
