What does it mean to whitelist your mobile phone number?

A white list refers to a mobile phone number that is not blocked.

The concept of white list corresponds to "blacklist". If a white list is set, users (or IP addresses, IP packets, emails, etc. ) will be given priority in the white list and will not be rejected as spam, so the security and rapidity are greatly improved. No matter whether your mobile phone only answers the phone in the address book or directly blocks everyone's phone, the phone in the white list can always come in directly.

The method of adding a mobile phone to the whitelist is as follows: Click the icon of the mobile phone to enter the contact page, click the symbols of the three dots in the upper right corner to open the drop-down menu, and then select Settings. After entering the menu, select "Call Block", and there is "White List" in the menu. Click Open, select "+"in the lower right corner, add a contact, select "Add from Contact/Call Record" option, and select a person in the contact list.
