I believe you have to run mbimcli with both '--no-open' and '--no-close'
to prevent it from breaking the connection by closing the MBIM session.
Look at the mbim-network script and see what it does.

Note that you need to provide a transaction ID for --no-open, but it
doesn't necessarily need to be part of any particular sequence.  You can
just make up a number.  For example, quering the IP config of my current
ModemManager managed session:


root at miraculix:/tmp# mbimcli -p -d /dev/cdc-wdm0  --no-open=42 --no-close --query-ip-configuration

[/dev/cdc-wdm0] IPv4 configuration available: 'address, gateway, dns, mtu'

    DNS [0]: '193.213.112.4'
    DNS [1]: '130.67.15.198'
        MTU: '1500'
