You can protect yourself from receiving unpleasant calls and SMS-messages using such a service as the "Black List". It is provided by the telecom operator "Megafon". To have access to the service, activate it, and you will be able to edit the list at any time (not only add numbers, but also delete).
Instructions
Step 1
There are many ways by which you can activate the Black List service on your phone. You can, for example, use the USSD number * 130 # or send an SMS message (without text) to the short number 5130. In addition, you have at your disposal the Megafon information service number 0500 (it is intended for calls). If you have already sent an application for connecting the service, then wait for the operator's message about this. A few minutes after you receive the first message, you will receive the second one. It will tell you that the service is now active on your phone. After receiving such messages, you can start editing the "Black List".
Step 2
The procedure for editing a list implies entering numbers into it and removing them from it. It is very easy to enter the number of an unwanted subscriber: dial * 130 * + 79XXXXXXXXX # on the keyboard of your mobile USSD number. It is possible to send an SMS message. It must contain the following text: + 79xxxxxxxx (the number must be indicated in the international format).
Step 3
If you want to remove only one number from the list, then it will be convenient for you to use the USSD command * 130 * 079XXXXXXXXX #. But to delete all numbers, that is, to completely clear the "Black List", the USSD request * 130 * 6 # will do. Once the list is edited, you can see all of the remaining numbers in it (or browse it and make sure it is empty). To do this, the operator provides the number for sending the request * 130 * 3 # and the number for sending SMS 5130 (the text of the message must contain the command "INF"). If you do not need the service at all, turn it off by SMS "OFF" sent to number 5130, or by dialing a USSD request * 130 * 4 #.
