When you need to block unwanted numbers (receiving calls, messages from them), just activate the service called "Black List". True, not all Russian telecom operators provide it, but only Megafon.
Instructions
Step 1
Before adding any number to the list, activate the service. This is easy to do if you dial the short number 5130 on the telephone keypad and press the call button. In addition, users of the Megafon network can send a USSD request to * 130 # at any time. After receiving the application, the operator will process it and immediately send two SMS messages to your mobile phone. One of them will contain a notification that the service has been ordered. And from the second you will learn that the "Black List" was successfully activated (or inactivated for any reason). After connecting the service, you can edit the list: for example, add numbers to it, delete them and view them.
Step 2
Then follow the instructions on how to blacklist a number. First, dial the special USSD request * 130 * + 79XXXXXXXXX # on the mobile phone keyboard. Also, instead of a request, you can send an SMS message (in its text you must indicate + and the number of the desired subscriber). Secondly, remember that each number entered in the list must be recorded only in ten-digit format through the seven, for example, in the form 79xxxxxxxx. Please note that if the number is entered incorrectly, the request will not be sent.
Step 3
After editing the list, you can view the remaining numbers in it, as well as check whether the necessary ones have been deleted / added. In order to view the black list, you can use the special number 5130. It is intended for sending SMS messages with the INF text. The USSD request * 130 * 3 # is also available for viewing.
Step 4
In case you want to delete any number, use the USSD command * 130 * 079XXXXXXXXX #. By the way, it is not at all necessary to delete each number separately, the entire list can be cleared in one step: dial * 130 * 6 # on the mobile keyboard.
