work all over India. This trick has been currently tested to be in
working only in tamil nadu. It has not even worked for me in kerala.
This trick will help you find out the balance of any airtel prepaid
number.
First dial 12140 from your mobile number(airtel). When the call
gets connected and language is chosen press 2.Next enter your
friend's or enemy's airtel mobile number. Note that the number should
be only 10 digit without any 0 or +91 at the beginning of the
number .The system replies the mobile number which you just entered.
Thirdly confirm it by pressing 1. It will surely ask for the PIN of
entered mobile number.Enter the PIN as 1234. This number is the
default pin and is mostly never changed. If it has been changed then
the trick would not work for you. At the end press 3 to find the
balance. The trick is especially beneficial if your friend tries to
fool you by saying that he/she has low balance. You can now find out
if he is telling the truth or not with a snap.
