You must download and using wvdial instead of NetworkManager. (You must re plug in the USB after using NetworManager if you want to use wvdial)
Using the console with this command:
sudo apt-get install wvdial
Config wvdial automaticly:
wvdialconf ~/.wvdialrc
Open and edit some information about the ISP
gedit ~/.wvdialrc
There are some information you need to fill in this file:
; Phone =
usually *99#
Phone = *99#
; Username =
Your login name. If dont have using
Username =
; Password =
Your password. If dont have using
Password =
The ISP may have the APN for each contract. You must add another line with the correct information (in this case APN is e-connect).
Init3 = AT+CGDCONT=1,IP,e-connect,",0,0
save the file and using command to conect
wvdial
There are my configuration to use for many ISP provider in Vietnam (you must use different command to connect each provider)
Like: wvdial dcom
