Answer 1

I slogged for days when i found it was this simple

First, run this command:

sudo wvdial.conf

This will set up the config file for you

Then run:

sudo wvdial

Shut down your wifi and run your browser and it will work,the problem is that the GUI for the network connections doesn't detect or is not able to connect to the modem but it is actually working.
