Will the leakage of mobile phone number affect the people in the mobile phone address book?

You may, for example, send a text message or call a group of friends in your mobile phone address book and ask for a transfer to a designated account for various reasons. Be sure to send a message to friends in the address book to inform them of the disclosure of personal information. After all, there are many cases where information disclosure is fraudulently used or cheated.

Install mobile phone security software for your mobile phone in time and update it in time, so that you can identify marked harassing calls. If there are harassing calls, you can identify them at the first time and re-mark them, which is helpful to others! If you are deceived, call the police in time.

Prevent the disclosure of personal information.

1, using the operator's sub-number: At present, the operator's sub-numbers are Unicom-Wo trumpet, mobile-and multi-number. Usually, relatives and friends use the main number to make phone calls, and the auxiliary number is used for unfamiliar calls or sales calls, but now operators only provide services with one main number and one auxiliary number, and the auxiliary number is fixed. If the minor number is often carried with you, it will also suffer from leaks and harassment.

2. Install security software: install security software for mobile phones in time (at least including harassing phone marking and interception functions). Android phones can install additional security software such as 360 guards. This kind of software supports ignoring the APP's application for permission from users, reducing the authorization of sensitive permissions such as address book, call records and short messages, and preventing the software from revealing personal information through the back door.
