Connecting to internet on Linux with Airtel GPRS and Nokia mobile phone

The Nokia phone comes with a software called Nokia PC Suite which provides many utilities including Internet connection on PC via phone. Unfortunately this software is not available for Linux operating system. But, as usual, a little bit of hack can enable Internet connection on Linux using Nokia phone.
Here is what I have tried and it worked for me with Nokia N79 and Airtel (in India) as service provider.
- Install wvdial. It was installed by default on my box (open suse).
- edit /etc/wvdial.conf as
[Dialer Defaults]
Init1 = AT+CGDCONT=1,"IP",""
Modem Type = USB Modem
Phone = *99***1#
Password =" "
Username = " "
Modem = /dev/ttyACM1
Baud = 460800
auto DNS = 1
- Now from command prompt, run the command wvdial
- The wvdial will block the command prompt. If want to disconnect, then type Ctrl+C on the command prompt.

- I faced an issue. It was not automatically obtaining the DNS address. So Manually edited the /etc/resolve.conf as
These two nameservers are public nameserver by google.

- The user name and password here is blank string. There is no user name and password for Airtel. This should be changed accordingly if there is different service provider.

- While connecting the phone to PC, select PC Suite when asked in the phone as "Select USB Mode"

- /dev/ttyACM1 can be different on different machines. run the command dmesg as root just after connecting the phone to PC (by USB) and look for a line similar to

cdc_acm 1-1:1.1: ttyACM1: USB ACM device

Change the device name in the /etc/wvdial.conf to what it appears here
