Awesome app ever created. Paytm is a great payment service that I am using since 3 year. Wallet app is also great for payment. Design/ UI great, this is very useful app for money tramsfer. Low data is used during transaction. This is very secure I think. Login is very very easy with just OTP. You need only your phone number to register and use it. Payment history, feedback, helpline etc is very useful service by paytm. I can’t find any drawbacks of this service and app. Paytm is a best wallet service, thank you Paytm.
