how can i get a mobile wallet

You will need a smartphone and data or wi-fi connection. If you expect to load upto INR 20000 rupees in a month, you will only need your mobile number. If you expect to load upto INR 100000, you will need KYC documents like Aadhar card and PAN card. If you do not possess a PAN card, you can still use mobile wallet, but you should submit the same as soon as you get one. KYC points are available near you, but you may first want to download the wallet and use it for upto INR20000.
