Incoming voice calls and SMS 2. Incoming voice calls only 3. Incoming SMS only In case of a blocked subscriber tries to make a call to you, he/she will hear the short ring tones. Short ring tones may be changed with special operator’s prompt or with your own greeting message. After the service is activated, the Black list automatically becomes active.
