When will the repayment SMS be sent?

Every month is a fixed date, and the repayment date in Bai Hua is 10. The order received last month has been confirmed, and there will be a text message a few days before the repayment date. I just checked the text messages. There are text messages on 1 and 7/,but you can log in to the mobile phone Alipay client at any time to check the bill. 1No. and No.7, 1No. told us the bill amount of last month, and No.7 told us to start automatic repayment immediately. Please keep the balance of Alipay or the express bank card with sufficient binding amount.
