Hide your Caller ID on your mobile phone

When you use your iPhone to call someone, your mobile number is shown by default.

If you do not want your number to be shown, follow these steps to hide your Caller ID

1. Tap Settings
2. Scroll and tap Phone
3. Tap Show my Caller ID
4. Toggle off the Show my Caller ID switch

Now whenever you ring someone, including those in your contacts, they should see Unknown Caller, Private Number, or No Caller ID rather than your name/number.
