Using Paytm for a year and I totally satisfied with its service and the speed of recharging, though the website load time is very high and same in the mobile app. But the recharge process is very quick and also gives great cashback every time you make recharge via Paytm.
The best part using Paytm is they provide cashback on every transactions with new coupon codes every time and the speed of recharge is also very fast. Paytm is trusted site and it is safe to use. It uses 128bit encryption to secure every transaction.
The worst part is website and android app takes long time to get fully load, I think its because of security reasons. If they gonna make it correct Paytm will become best online recharge website ever.
Online experience is great and smooth.
