How can someone else's overdue information be sent to my mobile phone?

There are several possibilities in this situation, and you can identify them.

First, your mobile phone receives spam messages. There is no need to pay attention to this situation, just delete it, and if it has a website, don't click it.

Second, if your mobile phone has been processed recently, it may be that the user's information was sent to your mobile phone before. This is also the case.

Third, when someone borrows money, the emergency contact person writes your mobile phone number.

This is basically the case.
