I am using this app.....All is correct & ok.....But when I am trying with my registered number it says that failed to fetch the sim because the sim is not in the same device.....Actually, when I register my phone number then this one was not linked with my Aadhaar & Bank account.....But , I am also use Paytm with this number.....When trying to connect or start a transaction then it says to add the registered phone number in my current device where the registered number is not present .....
