Make free calls from airtel

Ok friends,here is free calling trick in Airtel. Its not done by me actually,but its a flaw in Airtel server,which i've caught it since 18months,n in dis 18months,i'v used dis trick for 14 times,n has talked over 1600minutes for free.Can u believe it? No na,but its true.If u dont believe also,den u can ask Badboy,Toocool4all,Murtaza,etc of our forum.I'v also talked for free with dese ppl for nearly 1hour each.OK NOW HERE GOES THE WHOLE TRICK.1st u need to b a night rider to use dis trick,as we can only use it during night times.Hardly there is any chance during da day time,but den also i'v used dis 3 times during the daytime also.2nd u need to b very careful between 22nd of a month to 11th of da next month. During dis 20days only,Airtel updates its server or something of dat kinda.So,just u'v to catch dat special time,when they r updating their servers.HOW TO CATCH DAT SPECIAL TIME?U just need to check ur balance again n again after midnight. Now if u get a error msg everytime dat,REQUEST NOT COMPLETED,den dial 123. It wil say,"DIS SERVICE IS CURRENTLY NOT AVAILABLE ON UR TELEPHONE NUMBER". Now u r a free bird! Just call to any no n start talking for free. 1st just try calling for 1min,n if u find no deduction of balance,den just go on calling,but remember u've to stop ur talking before 4am,as nearly after 4am,the update their server,n ur balance may start deducting,but before dat there is no chance of cutting! Enjoy dis trick!BUT DONT ADVERTISE MY TRICK IN ANY FORUM OR BLOG SITES.I TRUST U,SO I'VE GIVEN,OR ELSE,I WAS NEVA INTERESTED TO SHARE DIS WITH ANYONE.REGARDS FRENDZ FAMILY...!!
