Paytm is very useful app ti do online transactions. Paying all types of bills also sending money to the other paytm customers. It is very useful to transfer the paytm amount or balance to bank account. We can easily understand this app because the design is so simple. Yes we have more number of apps and methods for online transactions but paytm was different. Because it gives promocode for every transaction through which we can get cash back and other benifits. I really like this app also I am using this.
