hit *67 before the telephone number you dial. First thing you hit. Example... *674102725713





You'll show up as Private Number or Unknown on the persons caller ID. I use this all the time if I dont want anyone to kno whos callin. But be careful this wont at all help you to block from the police or 911.
I think first hit *67 then the number (star 67).Wait for more answers to see if I'm right.
