Special

Well i know you wont be interested in using GPRS for connecting to net as it offers a download speed of 5KB/s instead of your broadband connection, but it can be of great help when you are traveling or when you dont have a broadband like me ( special thanks to BSNL for that).

I wanted to install Amarok on my newly installed Ubuntu 7.04 so i needed a net connection for that there were a hell lot of dependency as Amarok is basicly a KDE application. so my hunt began for a way to connect my Nokia 3250 with Airtel MobileOffice to it. I found a hell lot of sites upon searching for it but all of them required me to download some or other package for which i needed a net connection lol, but then on Linuxquestions.org i finally found a way to configure it without any extra package just the default Ubuntu Install and guess what it works with all Linux systems (it was originally posted for Fedora). So here is what to do

First:- check the VID and PID of your phone, To do this simpily connect your phone in PcSuit mode through the USB cable provided then type in terminal
lsusb

to get the output somewhat like this

ankur@ankur-desktop:~$ lsusb
Bus 003 Device 001: ID 0000:0000
Bus 002 Device 002: ID 0421:042d Nokia Mobile Phones
Bus 002 Device 001: ID 0000:0000
Bus 001 Device 001: ID 0000:0000

Notice the ID 0421:042d Nokia Mobile Phones here 421 is the VID and 42d is the PID replace them with what is shown in your case below. Now run the command
sudo /sbin/modprobe usbserial vendor=0x(vid) product=0x(pid)

Like “sudo /sbin/modprobe usbserial vendor=0×421 product=0x42d” in my case

then run the following command
wvdialconf create

To get the following output
ankur@ankur-desktop:~$ sudo wvdialconf create

Found an USB modem on /dev/ttyACM0.
Modem configuration written to create.
ttyACM0: Speed 460800; init "ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0"

This shows that a modem is connected at /dev/ttyACM0, Now substitute this at (your modem) in the script below
Enter the command
sudo gedit etc/wvdial.conf
delete any thing already written there and place this in that
[Dialer Defaults]
Modem = (your modem)
Baud = 230400
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
ISDN = 0
Modem Type = Analog Modem
Phone = *99***1#
Username = A
Password = B
Stupid Mode = 1

All done now to connect open terminal and type sudo wvdial and you are connected with the following outputankur@ankur-desktop:~$ sudo wvdial
