I use dis paytm to recharge mine and my family members mobile.recharge is instant and fast.the only thing which I want the developer to update this app is to provide a monthly bill of wht u hav recharged with bill n numbers.
For shopping also its provides a cashback offers.frm dis app I bought a ucb perfume frm which I hot 50% cash back.basically a nice app for rechargimg ur bills mobile data packs or dth services, and some online shopping.
