Can you run "AT+CGDCONT?" with minicom (or otherwise, running
ModemManager with --debug and then mmcli --command="AT+CGDCONT?")

Can you run these qmicli commands?
qmicli -p -d /dev/cdc-wdm0 --wds-get-profile-list=3gpp
qmicli -p -d /dev/cdc-wdm0 --wds-get-lte-attach-pdn-list

If your SIM card is O2 but the registration in the O2 network is not
working, it may still be the initial EPS bearer settings, I think you
should focus on debugging that.
