Previouslg we dont have such apps to get recharge. We have recharge cards and shops for recharge. I agree this is one of the good ideas and bes app.
But comparing with another apps as freecharge and many this is not at all good
It takes lots of time.
And sometimes fails to get recharge.
Even promocodes doesnt work properly in times.
I dont prefer paytm
Paytm is like pay your time.
