Code:
xxxxxx@xxxxxxx:~$ sudo dpkg -i LinuxDrivers_v1.0.5.001.deb
the device will be auto-mounted as USB (please, unmount it).

Then, create a "New mobile broadband connection":
GUI approach: edit connections>Mobile Broadband>Add

the required information must be supplied by your internet provider (in my case: http://support.sasktel.com/app/answe...ireless-device)

After that, you are ready to use the configured network!
