Paytm wallet is quiet easy to use.
Very easy to operate and the transactions are quick 99% of the time unless your bank has some issue or your internet connection.
I am using it since the demonetization drive of the government has proven quiet helpful.
I save lot of time and money using it and it really saved me from going to the long ques in ATM s for cash.
Its reliable and user friendly.
Even if you have some difficulty in transaction that team comes with a message to help you.
It provides features like billing option , money transfer, my own wallet of course I say its a bank tha you can carry all the way.
I have good experience with Paytm when I needed money urgently gave call to my friend and with minutes my friend transferred money to me.
And its safe trust me.
Just dont trust anyone else and dont give your ATM to any one.
