How long does it take for Alipay to apply for reducing penalty interest to receive SMS?

1 to 3 working days. The application for penalty interest reduction requires Alipay's review, and the SMS will be sent within 1-3 working days after it is approved, so users will generally receive the corresponding SMS within 1-3 working days. If you still can't receive the text message after more than 3 working days, you can go to Alipay Customer Service Center for consultation. Alipay's application for reducing penalty interest is to help users reduce the fees incurred by violations. After Alipay is approved, it can reduce the penalty interest and save unnecessary expenses.
