I was introduced to Paytm few months back through an offer by a famous noodle brand Yipee. Since then, I am hooked to paytm for all my prepaid mobile recharging. What I really liked about their service is that they are very technology oriented and introduce lot of useful stuff. I find their wallet system quite interesting. Usually what I do is to add thousand rupees to wallet and do the recharge as and when required from the wallet.
One of the good thing about Paytm is that they offer excellent service via their website as well as the app. When I bought a smartphone I installed their app and now recharge is as simple as entering the phone number and opt for "Fast Forward" feature and you are recharged in a few seconds from your wallet. They offer excellent customer support also. Once an order didnt make it and they promptly added the money back to my wallet. Paytm offers a lot of convenience as I can avoid now avoid spending time on prepaid recharges by standing in the long ques.
