That was the point:

mbimcli -p -d /dev/cdc-wdm0 --query-radio-state
[/dev/cdc-wdm0] Radio state retrieved:
             Hardware Radio State: 'on'
             Software Radio State: 'off'
mbimcli -p -d /dev/cdc-wdm0 --set-radio-state=on
[/dev/cdc-wdm0] Radio state retrieved:
             Hardware Radio State: 'on'
             Software Radio State: 'on'
mbimcli -p -d /dev/cdc-wdm0 --query-radio-state
[/dev/cdc-wdm0] Radio state retrieved:
             Hardware Radio State: 'on'
             Software Radio State: 'on'

After restarting the ModemManger, the sim-missing-problem disappeared.

In serial/ppp-mode the modem works now. The mbim-mode has still problems.

I attached the usb-trace unter linux while trying to ping 8.8.8.8 in mbim-
mode.

Thomas
