Airtel Unltd. 3G night Trick

So Here I am presenting the airtel trick by which u can get 2 nights of unltd 3g internet at Rs. 37 only,,,(In Rajasthan)

So here are steps to be followed:

Step 1 :- First of all , add a family member by following the steps.
              send a msg to 121 contains ADD<10 digit any airtel no.>
Step 2 :-  Then activate a 3G pack, I suggest the smallest one...
              U can activate the Rs. 21 Pack with 2 days validity and 65MB 3g net..... (PACK AVAIL. I RAJASTHAN)
              and U have to subscribe this pack after 12PM at night likely to be 12:05 PM... To be able to use trick for 2 nights....

Step 3 :- Now surf at least 10mins with this pack.
Step 4:- Now, Dial *129#,(YOU MUST HAVE ATLEAST 8 RS. IN YOUR BALANCE), now Select night store, then select Rs.8 unltd night pack at 2G speed, reply with 1 to confirm...
Step 5:- As soon u receive the msg of confirmation of activation unltd night pack, Disconnects the Data,,

And At LAST...

Turn on DATA After 5 mins.... And use unltd 3g all night (12PM-6PM)

and next night, just subscribe the RS 8 pack not the 21 one.......

So by this way u can use 3g unltd at 21+8+8=37 Rs..
