Mobile phones are often harassed by mobile internet phones, and the caller ID has no number or landline number. How to find out the real mobile phone number of that phone?

This routine method cannot be found. Ordinary people don't have this technology and have no relevant authority. We can only use some security software to prevent it. Take Baidu Mobile Guardian as an example, the operation is as follows:

First, the mobile phone is installed with Baidu Mobile Guardian, and then turned on. Enter the main interface and find the setting options. Then we turn on the tag interception option and turn on the corresponding switch. If you don't want to be disturbed by strange numbers, block all strange numbers.

Second, set the intercepted return tone to busy tone, or other options. This can effectively intercept.
