Try this. It was all that helped me get 12.04 to auto-connect.
sudo gedit /etc/init.d/mobile-broadband-connect
Copy/paste the following script in and where you see 8ta (2 places) you
have to enter your service provider. Then save and close gedit.
then
sudo chmod +x /etc/init.d/mobile-broadband-connect
sudo update-rc.d mobile-broadband-connect defaults
Then reboot and lets hope it works for you too.
Good luck
