Celebrities take enough precaution so that any call received from a stranger is not reachable to them because there is a closed circuit of the relatives such as Secretary, Managers, Security - personnels and other relatives taking maximum protection of the celebrities. Mobiles are purchased in such a way that the owners are ultimately their close - relatives.
Of course, it is the responsibility of the secretary to apprise the celebrity of important dates of shootings or any massage valuable to the celebrity. In that way, they don't miss any valuable message with such existing set- up.
They sometimes enjoy the facilities provided by the Telcom - operators and they offer them a special - status. In the event of making a contact to such a celebrity, you need to go in Face- book , e - mail or their official - websites.
