Question

How do you keep somebody from seeing the number of the person who is calling?

Answer 1

I dont know if you want...*67 or *69

Answer 2

141 and then the nr (if ur in uk)

Answer 3

*82 and then the number

Answer 4

*67

Answer 5

On my phones, it's *67 and then the number.  There should be a feature directory in your phone book, or on your provider's web site.

By the way, you should be aware this doesn't always work.  When dialing a toll free number, for example, the other party will always see your number.

Answer 6

You need to be calling from a number that is a non-published number, I believe.

Answer 7

In Malta it is hex 31 hex then the number. I don't know about the rest
