What do you mean by dongle?
Post the output of the console command lspci.

A USB serial port adapter will be /dev/ttyUSB0 if it is recognised.

As I understand this device requires usb_modeswitch so that it can be recognised as a modem device. What distribution are you running? No experience using a 3G MODEM so hopefully others will chime in.

It should be one of the red ones, I guess. So run dmesg on your system would be mu suggestion.

And you have seen the remark on the page you linked to about disconnecting from the internet before using the code?

NOTE:
this is probably not exactly the same device as yours !

Your airtel is most likely this one:

Bus 001 Device 005: ID 12d1:1436 Huawei Technologies Co., Ltd.

For how to get it working, see here...
http://ubuntuforums.org/showthread.php?t=1996734

Note that udev maps devices all over the place, especially serial ports,... so you can have your modem plugged into the first USB port, and this time it'll be /dev/ttyUSB0,... but next time it could be /dev/ttyUSB1 ... No rhyme or reason... The Roman Catholic Church has the mysteries of faith,... Linux users have udev. Udev rules help tidy it up.

To determine the details of the ACTUAL physical device you'd be looking at the /proc system... Which is part of what lsusb does... In the above case, bus 1, assigned as device 5.
