Why do people send me messages when their online loans are overdue? Is it illegal to leave my phone number?

Yes, it is legal for others to send you messages after the online loan is overdue. Here are some key points to explain why:

1. Contract agreement: In the loan contract, the contact information provided by the borrower, such as telephone number, may have been clearly agreed. According to the agreement, the borrowing company has the right to use these contact methods to communicate with the borrower.

2. Repayment collection: When the borrower fails to repay the loan within the time limit, the borrowing company has reasonable reasons to contact him to urge repayment. They will try to get in touch with the borrower through different channels (including phone calls, text messages, etc.). Remind them to repay or negotiate a solution.

3. Privacy protection: Although the borrower provides the telephone number, the borrowing company should abide by the relevant privacy protection regulations when using this information. They need to handle their personal information carefully and must not disclose it to other third parties or use it for illegal purposes.

Summary:

The borrowing company can communicate with the borrower through the left contact information to urge repayment or solve problems. However, they must abide by the privacy protection regulations when using this information. If you think that the behavior of the borrowing company violates relevant laws or abuses your personal information, you can seek the help of relevant legal institutions.
