How do I call someone and it shows up as restricted on thier caller ID?

It is a setting that needs to be changed with your telco. Most phones have a menu option that will allow you to check or change the restrict/reveal ID settings.

In my Razr its under
Settings/In Call Set Up/My Caller ID/Next Call Only/Hide ID or Show ID

I’ve got a Samsung and in mine it’s under setting/network services/caller ID

Can’t you hide your caller id by pressing *67 before dialing the number?

@SuperMouse not if you are in a country that does not recognise *67.
Here (Australia) we (1832/1831) to turn ID on and off.

I think the bigger question is, how old are you and why haven’t you moved past the appeal of prank calls?
