On any GSM mobile phone, dial #31# before the number to suppress display of your caller ID information.

To hide your local mobile number while making calls, you can use the caller ID blocking feature provided by your mobile carrier. This is typically done by dialing a specific code before the number you wish to call (e.g., *67 in the U.S.). Additionally, you can check your phone settings to enable "Hide Number" or "Block Caller ID" options. Using a third-party app or service that masks your number is another alternative.
