That is a great question, woonie. You came to the right place for help. Let's ensure we get your questions answered. To clarify is this person looking to set up a new account with Verizon once the phone's device payment agreement is completed? Also, would this be the mobile number associated with the device loan that wants to get their own plan? Assuming that is the case, it would really depend on if they qualify for a device payment agreement or not. For example, if the user of the phone number associated with the device loan wishes to assume liability of their line and loan, they would need to qualify and pass a credit check. If they don't qualify, then you would need to ensure the loan is paid off before moving the number to their own account under their name. Does this make sense?
