If the mobile phone number of the payment package is changed and bound, is the payment reminder sent to the new number or the old number by SMS?

Your Alipay has changed its bound mobile phone number, and the text message must have been sent to a new number. But in order to avoid forgetting to repay, I suggest you set up automatic repayment. At the same time, it is recommended to set a reminder on the mobile phone, which will automatically remind you when it expires. Sometimes too many text messages will inevitably delay.
