USB internet Data card modem on Linux

Here is procedure for connecting USB interent Data card on Linux box.

I have tested it on Reliance,Tata and BSNL card on linux.

1)Connect USB Data card on USB port of computer

2) Open a terminal window.

3) Log in as root, i.e. type “su -” sans the quotes and enter the root password.

4) "wvdialconf /etc/wvdial.conf" It will create a wvdial.conf file in etc directory (Please remove quote ).

5) Then use to edit the file “/etc/wvdial.conf”.(you can use any editor I would recommend gedit. Command would be “gedit /etc/wvdial.conf”).

6) Enter/edit the following text into this file.

[Modem0]

Modem=/dev/ttyUSB0

Baud=115200

SetVolume=0

Dial Command = ATDT

init1=ATZ

init2=AT+CRM=1

FlowControl= Hardware (CRTSCTS)

[Dialer Reliance]

Username= username

Password= password

Phone= #777

Stupid Mode= 1

Inherits = Modem0

7)Disable network connection of your computer

8) Final step is giving the command “wvdial Reliance”, and if everything is proper you should be able to connect to the internet.

For Tata: username and password is “internet” without quote

For Relianace : username and password is phone number of the device

For BSNL modem: its username and password is “cdma”

I used only three USB modem till this time but I hope it will work for all the USB modem.

Please let me know if you get any problem in your connection.
