Now almost any mobile phone has a blacklist function. It is convenient in that it frees the owner of the phone from unwanted calls from known numbers. And those people who call, in response, usually hear short signals, notifying that the number is allegedly busy.
Instructions
Step 1
In order to create your own "black list", go to the main menu of the phone
Step 2
Select the "settings" menu. Select the "calls" menu (on some models there is an intermediate menu "call log" or simply "log").
Step 3
Select the blacklist menu. From the phone book or manually enter one or several unwanted numbers
Step 4
Save your changes.
Step 5
This algorithm may differ insignificantly for different manufacturers of mobile phones, but the principle is exactly the same.
Now everyone, whose numbers you have placed in your own "black list", instead of the usual beeps or melodies, will hear short signals, or even receive notifications about the absence of a subscriber in the network.
