title: How does Uber app defines the limit to maximum signups for a device?
body: <p>I got an old phone to operate on. This phone already had an Uber app which the previous user was using. I reinstalled Uber app and register there with my email id and phone number.However, now I am not able to add the paytm wallet in this. While doing so it gives me a message "We are sorry but this device has reached the maximum signup limit." Also, I don't have any paytm app in my phone.</p>
  
  <p>I have few questions like</p>
  
  <p>1) Which party is defining the rules here, Uber or Paytm? </p>
  
  <p>2) Do they maintain their own file(in their apk) for this calculation or it can be some common android file which the app has pickup even after the re-installation and later giving me a message for maximum signups. If this some android file, Can I somehow edit this?</p>
