If you do not want to communicate with any subscriber (or even with several), then the Megafon telecom operator offers you a special service, it is called the "Black List". From the moment you connect it and add the desired number to the list, the caller will only hear the message that the number is not available.
Instructions
Step 1
As already mentioned, first you need to activate the service, and you can choose any convenient method. To activate the "Black List", use the USSD-command * 130 # or, for example, call the short number 5130. A few minutes after sending a request to one of these numbers, the operator will receive it and process it, and then send it to you with an interval of two three minutes two SMS messages. The first is that the service has been ordered, and the second is that it has been successfully activated. Once you receive both of these SMS, you can edit the blacklist.
Step 2
You can block any number using this service by sending an SMS message with a + sign, as well as the subscriber's number, or by sending a USSD command to the number * 130 * + 79XXXXXXXXX #. In this case, do not forget, by the way, to indicate the number of the other subscriber in ten-digit format (and after seven, that is, in the form 79xxxxxxxx). If this condition is not met, then you can either not send the request at all or send it in an incorrect form.
Step 3
In order to remove any number from this list, simply dial the USSD-number * 130 * 079XXXXXXXXX # on the phone keypad and press the call button. You can also send an SMS message with the sign - and the number of the subscriber you want to remove from the list.
Step 4
You can check which numbers are on your blacklist via a USSD request to the number * 130 * 3 # or by SMS to 5130 (the text must contain the INF command). If you want to delete all the numbers remaining in the list in one action, then use the special command * 130 * 6 #. To deactivate the service, there are numbers 5130 and * 130 * 4 #.
