It's clearly not a ModemManager issue, but an NM issue.  Could you run
NetworkManager with these options?

/usr/sbin/NetworkManager --no-daemon --log-level=debug
--log-domains="core,hw,device,agents,ip4"

and post the log output?  Also, can you paste in the connection file
from /etc/NetworkManager/system-connections (taking out any information
you consider confidential, of course).

Thanks,
