Ok, because this problem also exist under Windows, I assume it has
nothing to do with the network manager. Maybe it is the firmware. Under
Windows XP it says that the sim card detect failed.

Emmanuel ... you have a different hardware, please don't make this bug a
catch-all thing that cannot be handled :).
Simon, so does it make a difference whether you properly disconnect
through NM before reconnect? Did you replug the device in between?

I forgot to add that the suspend symptom is the same as described up

If that doesnt help also run "sudo /etc/init.d/network-manager restart"
