A reminder for the repayment of the principal of Nanjing Bank's consumer loan should be issued a few days before the repayment date.

1. In order to avoid overdue mortgage, mortgage banks usually send repayment reminder messages one week in advance. After receiving the message, users can prepare for repayment in advance.

2. Of course, whether you receive the reminder message or not, the user must repay the mortgage on time. If the mortgage is not repaid on time, the overdue mortgage will have more negative effects.

3. The standards of major banks are different. Generally, the repayment is notified about three days in advance. I suggest you call the bank's customer service telephone for consultation, and it is best to repay according to your bill date to prevent overdue. In fact, there is no SMS, and online banking is ok.
