Make your number private when making a call

A private number is hidden on the screen of the person you are calling.

To check whether your number is permanently "Private" or "Shown" pick up your home phone and call:

127220

On a call by call basis, you can make your number private. Simply add the following number before the actual number you are going to call:

1831

Eg: if you were going to call 52444222, you would actually dial 183152444222
