I have been using Paytm payment services for last two years. Basically I use the Paytm App for my Android phone and make payments to various merchants.
I like the Paytm Wallet feature where I can store some amount of money and pay instantly where ever needed.
Features like mobile recharge and bill payments are quite helpful. No need to worry about paying your electricity bills, recharging your DTH, etc.
I can book tickets for movies, trains, bus, flight, etc.
Paytm Mall offers goods at affordable discount prices.
Also there are various cashback offers for the users in buying certain items.
The interface of Paytm is simple and user friendly.
