  1. Open the application "Phone"** and go to the tab Keyboard.

  2. Enter the USSD code for your operator:

    *110*789# - for MTS

    *105*789# - for MegaFon
    

    *220*1# - for Tele2

  3. Press the call button - you will receive an SMS with a list of blocked numbers (or a notification about their absence).
