Blocking unwanted phone numbers is a useful feature that can help protect your privacy and peace of mind. Blocking a number prevents the person associated with that number from contacting you via phone calls or text messages.
There are several reasons why you might want to block a number. For example, you might want to block a number if the person associated with that number is harassing you, sending you unwanted spam messages, or making prank calls. Blocking a number can also be helpful if you are trying to avoid contact with a particular person.
