STEP 1. Simply tap the Settings Button on your iPhone.
STEP 2. Now you have to scroll down until you see the Phone settings, then simply tap on “Phone” settings.
STEP 3. Now you have to tap on “Show My Caller ID”.
STEP 4. Now simply toggle the setting to either “On” or “Off” as you like.
That’s it. If you want to block your caller id then simply toggle the settings to Off. Now if you call someone then your name and number will not be displayed on the iPhone. In this way you can block your caller id on the iPhone. If you found any difficulty in following the above steps then feel free to ask in the comment section below.
