Can you try some PPP debugging?  You can enable that in NM by:

1) stopping NetworkManager
2) running NM as root like:

NM_PPP_DEBUG=1 /usr/sbin/NetworkManager --no-daemon

3) try to connect the system 3G connection
4) grab the output from NM/pppd and reply with it to this mail

That should tell us more about what NM is doing.
