How to inquire whether a phone number is fraudulent or harassing?

If you are a smartphone user, you can install 360 mobile guards, Tencent mobile housekeeper, Baidu mobile guards and other similar software.

These softwares integrate anti-spam messages, anti-harassing calls, anti-privacy leakage, mobile phone security scanning, anti-malware detection in the networked cloud, real-time detection of software installation, full-process control of traffic usage, acceleration of mobile phone system cleaning, display and query of place of ownership and other functions.
