My ex-boyfriend's loans overdue record was sent to my mobile phone text message, but he doesn't have my current mobile phone number. What happened?

Maybe the emergency contact filled it out for you.

When your boyfriend borrows money, he leaves your contact information as an emergency contact. After your boyfriend loans overdue even loses money, the platform will send dunning information to the emergency contact's mobile phone, so that the emergency contact can remind the debtor to repay in time.

Another possibility is that your boyfriend borrowed an online loan platform. In the application stage, the online lending platform will read the address book in the borrower's mobile phone, especially the recent contact records. After the borrower fails to pay back within the time limit, the online lending platform will send a message to all contacts in the address book.
