I have been using this freecharge for last six months. Here I will tell you what is the special in this app. First thing when we do recharge to any of your moblies, DTH or data. It asks for OTP for that transaction. Once if you select that you ill get an OTP in your mobile.
That time this freecharge app automatically detect that OTP you dont want to open your massage inbox and retype the same thing. And it easy to used & it eye catching well design. So I preferred this to all .Use it and see the changes from your normal app.
