You can block or hide your number or caller ID on freedom mobile to make some calls if you wish to appear anonymous to your caller. Usually, people use #31# on a per-call basis before each phone number or *67 to hide their caller ID.
However, this may not work for some mobile devices as they may require other methods for you to hide your caller ID or number. To permanently block your number, Go into the Phone app, swipe down from the top to access Phone settings. There is an option for “Show My Number” and you can toggle it off.
If you have an android device, go to “call settings” select “all calls” then “show my number” or “hide my number”.
