need information for "non stop mobile"

i just saw in todays news paper abt this "non stop mobile" from tata indicom.it says we can get free incoming calls for 2 years without recharging it.even if u recharge 50/- voucher u will get 2 years unlimited incoming calls.if it is true,its awesome 😀 i need some more information from u(expert) people.bcz this offer looks too much to me.iam sure there will be some hidden things in this offer.if u know abt this,pls do postthanks

its simple firoz bhai. You get a new tata indicom phone from them and then u recharge with any amount the validity for the same is 2 yearsSO the catch is that you need to buy a phone....
