Connect Airtel-Mobile Office in Ubuntu!!?

I am using Samsung SGH-L700 and I wanted to use Airtel Mobile Office in Ubuntu. Finally when I am succeeded in configuring it in Ubuntu. I would like to share it with everyone. Here are the steps:

Before proceeding you need to make sure that wvdial package is installed in your machine.

Step1:- Just type wvdial in terminal to check if it is installed. If yes, then proceed otherwise type the following command in terminal to install.

sudo apt-get install wvdial

Step2:- Now follow these commands :

wvdialconf

This will scan and detect the serial ports of the modem which is connected. It will then edit the file called wvdial.conf which is present in /etc/ .The expected output is :

Editing `/etc/wvdial.conf’.

Scanning your serial ports for a modem.

Modem Port Scan<*1>: S0   S1   S2   S3
ttyACM0<Info>: Device or resource busy
Modem Port Scan<*1>: ACM0
ttyACM1<Info>: Device or resource busy
Modem Port Scan<*1>: ACM1
WvModem<*1>: Cannot get information for serial port.
ttyACM2<*1>: ATQ0 V1 E1 — OK
ttyACM2<*1>: ATQ0 V1 E1 Z — OK
ttyACM2<*1>: ATQ0 V1 E1 S0=0 — OK
ttyACM2<*1>: ATQ0 V1 E1 S0=0 &C1 — OK
ttyACM2<*1>: ATQ0 V1 E1 S0=0 &C1 &D2 — OK
ttyACM2<*1>: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 — OK
ttyACM2<*1>: Modem Identifier: ATI — SAMSUNG SGH-L700
ttyACM2<*1>: Speed 4800: AT — OK
ttyACM2<*1>: Speed 9600: AT — OK
ttyACM2<*1>: Speed 19200: AT — OK
ttyACM2<*1>: Speed 38400: AT — OK
ttyACM2<*1>: Speed 57600: AT — OK
ttyACM2<*1>: Speed 115200: AT — OK
ttyACM2<*1>: Speed 230400: AT — OK
ttyACM2<*1>: Speed 460800: AT — OK
ttyACM2<*1>: Max speed is 460800; that should be safe.
ttyACM2<*1>: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 — OK

Found an USB modem on /dev/ttyACM2.
Modem configuration written to /etc/wvdial.conf.
ttyACM2<Info>: Speed 460800; init “ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0″

Step3:- Now its time to make some necessary changes in your wvdial.conf file in /etc/

sudo gedit /etc/wvdial.conf

Major changes required are Phone, Username & Password. Changes are as follow:

[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Modem Type = USB Modem
ISDN = 0
New PPPD = yes
Phone = *99***1#
Modem = /dev/ttyACM2
Username = ‘ ‘
Password = ‘ ‘
Baud = 460800

Dialing phone number for Airtel Mobile Office is ‘*99***1#‘  Username and Password should be left blank.

Save and exit once you are done.

Step4:- Now you are ready to connect. Type the following command:

wvdial

Output expected is as follow:

–> WvDial: Internet dialer version 1.60
–> Cannot get information for serial port.
–> Initializing modem.
–> Sending: ATZ
ATZ
OK
–> Sending: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
OK
–> Modem initialized.
–> Sending: ATDT*99***1#
–> Waiting for carrier.
ATDT*99***1#

You can follow Step2 and Step4 next time you want to connect to internet…

I hope it helps!!!!
