This should be same basically.

For grins you could boot to a live ubuntu and try it also.
Here you have it.
ifconfig
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
inet6 addr: ::1/128 Scope:Host
So that is OK. See it has IP addresses but no use to you.
wlan0 Link encap:Ethernet HWaddr 48:51:b7:d2:a3:43
UP BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:33688 errors:0 dropped:0 overruns:0 frame:0
TX packets:26242 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:19447613 (18.5 MiB) TX bytes:6862650 (6.5 MiB)
So this has no ip addresses and of no use to you since it is for your wifi.
From wiki it suggests to now go to.
"At this point jump back into the Ubunto GUI and Enable Mobile Broadband in the top row under the antenna icon. It will step you through setting up a new connection.
Respond with the following for the usual connection to the Internet using" APN info....
Is said that after you make this new connection (assuming sim installed, registered and such) the new wwan0 interface should show.
Some of your versions do seem to be older. The direct IP as in later drivers should work.
Note, don't post to your post. Edit instead. Makes it look like this is being helped.
