If that MBIM operation is not supported by your module, then you can
always fallback to what you were already doing with AT commands; i.e.
set the auth settings for PDP context #1 (or #0?) using whatever AT
commands you were using before. E.g. you could disable the modem, put
it in low-power mode (so that it's unregistered from the network) and
then use mmcli --command="AT+whatever" for that, and then enable the
modem.

Anyway, we could always improve the Telit plugin to do this properly,
i.e. if the MBIM operation is detected as unsupported, switch to
AT-based configuration of the initial profile, as we do e.g. in
Cinterion plugin.
