Caller Identification or "Caller ID" allows a person receiving a phone call to see who is calling before answering the phone.
You can choose if you want your number to appear as private by blocking it for each call or every call.
To block Caller ID once
- Dial *67 before dialing the telephone number.
- Dial *30# to turn on (you'll hear a single beep)
- Dial *31# to turn off (you'll hear two beeps)
