Paytm is one of the trustworthy app. We can have many of the task to be performed at single place using this app just like mobile recharge, electric bill payments, DTH bill payments , online Shopping and many more, as it directly links to your bank account through your ATM card so their is no need of making online banking. Its only drawback is that it takes some time for the recharge if we are using slow internet service, besides its other services are too much better than other apps.
As I said that it is trustworthy and I myself use it for my daily basis its new updates had also many offers giving the best offers of cashback daily, cashback on movie tickets, etc besides it is one of the best app. Must use
