Free charge is a good app to recharge our mobiles, electrical etc., And I have a lot of experience with this. Whenever I need to recharge my account I will pay trough this app. And it will give cash back offers. I got many times cash back When I was recharged my mobile. And I have booked my train ticket in IRCTC trough this free charge with less payment. And we can buy products in Free charge itself or we can pay trough this app. This is very good app.
