Hello, the installment amount is your actual available amount. If your current actual available amount is insufficient, you can't make the installment transaction for the time being. If the installment cannot be handled due to insufficient quota, the following methods are suggested: (1) Apply for increasing the fixed quota; (2) If the amount is insufficient, the installment transaction is completed by depositing the corresponding amount of money (that is, overpaying the installment); This requires manual application.
