No matter what kind of loan app or loan platform, it will only explode the address book after a long period of overdue. For example, if the borrower is overdue for one day, there may be a dunning call or text message, and the lender will pay off the loan quickly. But if you don't pay back the money, or don't answer the dunning call, or even disappear, your family or friends will receive the dunning call sooner or later. Therefore, after overdue, the lender should pay off the arrears quickly to avoid unnecessary troubles. Moreover, it is necessary to avoid overspending and reduce the loan amount.
