I would like to ask everyone to log in to Alipay to borrow money. Can someone else's mobile phone receive a reminder message?

First of all, to correct you, Alipay can't borrow money, but can only be used for payment. Alipay can borrow money. You use your mobile phone number to log in to Alipay. Once the repayment cannot be made on time, Alipay will only send a reminder message to your mobile phone number, and will not send a reminder message to your other relatives.
