Would you provide more detailed logs (http://live.gnome.org/NetworkManager/Debugging)?

Steps:
* Stop NetworkManager
* killall -TERM modem-manager
* modem-manager --debug
* in another terminal, run NetworkManager like this: 
  NM_PPP_DEBUG=1 /usr/sbin/NetworkManager --no-daemon
* reproduce the problem and paste in the logs

Is there any update or progress on this? Is there anything else I can provide?

What behaviour do you actually see? Is your modem enabled in nm-applet?
Are you able to see your connection in nm-applet menu?

One problem I found in the last log is the username in a connection is invalid, which prevents it to be shown in editor and nm-applet.

Could you re-run the steps in comment #3 with --log-level=DEBUG added to the NetworkManager command line.

What is output of:
nmcli nm

There is normally no username for the connection, just the dial number (#777). I did see the username item in the debug output but disregarded it as both my other laptops (OSX, F12) are setup with no username or password and connect to Verizon without issue.

Apparently this was the problem though. I used random text for the username and everything is working now. Perhaps NM requires that there is something in that field now?
