Latest AIRTEL Mobile Office Trick

Hai to all AirTel gprs is free as in my case .
Technology r changing rapidly so u must change accordingly. .
This trick will definately work but u have to spent RS 249 first then enjoy i dont know till when.
Althogh i have many tricks but first try ths and one more thing is my own trick not taken frm anywhere .
Its almost impossiple to surf free, from airtel live due to strong firewall.so now, dont worry
recharge ur mobile with rs 333 i.e full talktime.call 121 press 1,4,9 and tell them to activate mobile office . after some time it will b activated .
NOW REMEMBER THE DATE WHEN UR GPRS GET ACTIVATED . thats it.
Next month same date make ur balance between RS 1 to RS 5. no charge will b cut but if u r unlucky if it gets cut also it will go -RS 30 no problem do the same procedure 3rd month no fees wil b cut i n enjoying frm last 8 months. so as technoly changes u have to b smart . remember its impossible to surf through airtel live

THS TRICKS ARE NOT MY OWN BUT RESPONSES HAVE BEEN POSITIVE
