What are the previous 10 lines here? Does the modem really
respond
to
AT+CGDCONT=? with unsolicited ^SCFG output or is that left-
over
from a
previous AT^SCFG=? request that MM is making?

This is a modem that only supports IPv4.
How can I get around this problem?

Ok, here's the problem. Could you grab the ModemManager
debug
output?
mmcli --set-logging=debug
and then replug the modem (if you can!) or rmmod the
modem
drivers
and
modprobe them again. We're looking for the response to
the
"AT+CGDCONT=?" command and why MM apparently doesn't
parse that
correctly. That'll look something like this:
