Question: I recently switched from Win 7 to Ubuntu 12.04...Best day of my life :)

I have a question relating to my Vodafone K3772-Z USB modem. When I plug it in, the lights start flashing on the device, meaning that it is functional. In the network menu I get a "Wired network Vodafone K3772-Z disconnected". I have set up the a connection by using Edit connections -> mobile broadband -> Add, but in the add window the "Create a connection for this mobile device" is blanked out and says "Any Device".

Does anyone perhaps have an idea of what I could do to get it working?

Answer: 
You can use [SAKIS3G](http://www.sakis3g.org/) to form a connection without unlocking it. I never unlocked the device and it worked fine. 
NOTE: I could also use another network's sim on a network locked device using SAKIS3G.
Just bought a Vodafone K3772-Z USB modem. Could not get it to work at all in 12.04 but, I have dual boot Windows 7 and 12.04.

Boot into Windows 7 and allow the Vodafone K3772-Z USB modem to register, install and check that its working. Then reboot back into Ubuntu. 

Click on **Network Manager** indicator → **Edit Connections** → **Mobile Broadband** tab → **add the new Vodafone connection**. 

It worked the first time without any issues. Why, I don't know. But, there must be something in Windows which has to activate the device first. 

Hope this is of help.
