Do really sites like paytm and the other one you metioned give free recharges, how much you get , what amount of effort required in return ?
yeah, i use freecharge frequently, you just have to enter your number, the carrier, the amount. select coupons if you want and done.. you get coupons worth the value of your recharge rounded off to the next 50 multiple.
you also need to be logged in..
