Comment 25 for bug 933972

That looks like the correct drivers. If you run "ifconfig -a" do you see a wwan0 interface listed? If not, then I'm not sure what else to do as I am running from one of these devices right now.

If the wwan0 interface is there then it should be appearing in Network Manager. There should also be a new option in the network menu for "Enable Mobile Broadband". You will also see a bunch of stuff appearing in the syslog at /var/log/syslog after plugging in the device.
