how do you set a phone to make outgoing private calls?

Question

i have a motorola razr, how do you set it so that outgoing calls show up as private on a caller ID?

Answer 1

dial *67 before the ten digit phone number. this will block your number.

Answer 2

Go to your tools,In call setup,my caller id,next call only. My Motorola phone only allows me to block for next call only and then have to go back to tools and change again. I don't know how similar the razr is.
