How does Apple block phone calls and text messages?

1. Open the settings icon on the main screen of iPhone, enter the settings, turn down the page, find "Do not disturb mode" and open it directly;

2. At this point, the Do Not Disturb mode is turned off by default. Slide the switch button on the right to turn it on.

3. After opening the Do Not Disturb mode, click the "Allow the following calls" option at the bottom of the page;

4. At this time, if you want to prevent the harassment of all unknown strange calls, then directly select all contacts here.

5. Then, on the do not disturb mode Settings page, select the "Always" option under "Silent Mode";

Reminder: The above methods are suitable for blocking all unfamiliar calls, and all settings will not affect the normal contact of contacts in the address book. If someone in the address book is harassing you endlessly, then remove the address book, or completely block it with the "block contacts" at the end of the tutorial to give yourself a quiet living environment.
