If you want to recharge your mobile or internet pack, go with freecharge as it gives you some offer on your user id . AS we see for new user get 50 cashback on first recharge of 50 rupees . But freecharge sometimes also offer you with special offer only for you and the code are sent to your registered e-mail id.
I used to recharge on it for a long time and their is no problem occurred with me . recently I get offer fro it .and you also can pay your electricity bill on it without going to wait in a Que .and it als o provide me an offer of 10% cashback on paying above 300 ruppes and I saved approx 40 rupees o it. and with every transaction on it they give exciting coupon to .
I like the most about it its user interface and the ease of doing recharge on it .And if you pay with your card you save your card detail on it.And if you are affraid of it that it would not be secure than you also can remove your saved card detail in it, As this option is not given on paytm.
