Is it true that the car loan is overdue for more than 20 days and the loan is stopped by SMS?

This is not true. According to the "Measures for the Administration of Automobile Loans", there will be a penalty interest for the automobile loans overdue 1 month. If it is overdue for more than 3 months, you can call or collect it at home. If it is overdue for more than 6 months, you can sue to stop the loan installment according to law, and the mortgage will be frozen by the court. Therefore, it is not true that the car loan is overdue for more than 20 days by sending a text message to stop the loan installment.
