I received it inexplicably. What happened to the payment amount text message of Anfubao?

Hello, I would like to ask what happened when I received the payment amount SMS from Alipay inexplicably. Inexplicably received Alipay payment amount SMS, because the mobile phone number was used by others. Others used it to register the corresponding Alipay account. If he doesn't change his mobile phone number in Alipay, the payment amount text message will be sent to your mobile phone.
