Dear Aleksander,

The question arose from this post:

So I tried `$ mbimcli -p -d /dev/cdc-wdm0 --get-signal-state` and
expected some hint on LTE or 3G in use.

What I obtained instead was:

/dev/cdc-wdm0] Signal state:
              RSSI [0-31,99]: '8'
         Error rate [0-7,99]: '99'
    Signal strength interval: '5'
              RSSI threshold: '2'
        Error rate threshold: 'unspecified'

What does this tell about the "access technology in use" you mentioned?

Best wishes,
Friedrich
