1)-buy a new sim card of vodafone(hutch)from a near shop with validity of 6 months or whatever you may want.(only for new users) 2)-activate gprs in your vodafone sim. 3)-keep a balance of rs 5-10 and use gprs on it for 2-3rs.. 3)-now after using gprs you'll have to use money left with you.use dat money instantly and call any one from dat balance and after dat keep your balance after call to around 20paisa or less than 1 rs.i.e- less than the amount which used for gprs. 4)-now leave the mobile for some time till your balance goes in minus.when it'll go in minus then use it as much as you want and you won't be charged any thing for dat.but dont try to re-charge very soon after use. 5)-if your balance goes in minus after the use then bear it in your mind dat you have succesfully hacked vodafone for free gprs. try it and tell me.its 100% working trick.no doubt in iT,
