If you do not want someone to know you are calling them. Just type *67 or #31# before the ten-digit mobile number of the person you are calling. Some providers will provide a confirmation beep or tone after you dial *67, so wait for the regular dial tone to return before dialing the 10-digit number you wish to call. Some countries have different codes, such as 141 in the United Kingdom or 1831 in Australia.
