Hello friends, this is a new trick for free Airtel GPRS for you.Using this trick, you get a packet of bandwidth of 10 GB 3G.
For this trick your handset must be 3G compatible.
Now give me a favor to do:
Post a new message "3G".
Send this msg to 121.
After a while you get a msg reply.
Now select the desire plan & reply it again.
After selecting your plan, you receive a msg with a full list of plans for 3G.
Just select the 10 GB plan and wait 5-6 hours.
Now you have your plan of free Airtel 3G 10GB.
Enjoy.
