How to configure UTL CDMA internet on Ubuntu

This method works with Ubuntu 8.04 LTS but for later versions of Ubuntu you have to install the wvdial package before you configure your CDMA Modem. 

There are some devices which is compatible with Ubuntu. To determine if your device is compatible just run this command on terminal.          

$ ls /dev/ttyUSB*

If the result is
/dev/ttyUSB0 , then your are lucky mate.

Now you have to modify the /etc/wvdial.conf file. In terminal do

$ gksudo gedit /etc/wvdial.conf

here is how my file looks like (for UTL CDMA)

[Dialer Defaults]
Modem = /dev/ttyUSB0
Baud = 230400
Init1 = ATE0
#Init2 = AT$PBTYPE=1 RPTCON=1 MTRPTTYPE=3 SMSRUIM=0 SMSTYPE=1
Init3 = AT+CTA=0
Init4 = ATEOV1
Init5 = AT
Init6 = ATS0=0
ISDN = 0
Modem Type = Analog Modem
Phone = #777
Username = myphonenumber@utlnepal.com
Password = myphonenumber
Stupid Mode = 1
New PPPD = yes

Save it and then dial

$ sudo wvdial

after about 15-20 seconds it should give you the ip address, enjoy you internet mate.

To disconnect internet simply press Ctrl + C on the terminal.
