With some new advancements on iPhone, such as iPhone X, iPhone 11, and iPhone 12, there is a feature on your phone known as “Silence unknown Callers.” You can easily locate it with its icon.

Silencing the unknown caller function is to the new model iPhone to directly transfer no caller id calls to voicemail and leave the call notification on the phonebook without ringing out, and for the phone owner to be aware of the call to take quick action to block it.

FIRST METHOD: Activate The” Silence Unknown Callers” Mode

Follow this step to activate the unknown silent caller on the new model’s iPhone.

1. Go to the “settings” icon on your iPhone home screen

2. On the settings page, scroll down to select the “Phone” option

3. On the phone page, select the “Silence unknown caller” option, then activate the feature by sliding to the right until it turns green.

4. By activating the “Silenceunknown caller” mode, you won’t receive notifications when spam or unknown caller id calls come into your phone.

SECOND METHOD: Activate The Do Not Disturb (DND) Mode

Using the DND mode is another method you can use to block and avoid the no caller id calls on your iPhone. Using the  “Do not disturb feature.”

2. Swipe down slowly through the settings page, then select the “Do not disturb icon.”

3. Click “Allow Calls From,” then choose the “All contact Option.”

You should note that the “Do not disturb” mode allows only calls from the contacts saved on your phone; you will not be able to receive calls from numbers you don’t have on your contact list. And this might be other relevant calls besides the spam calls.

Therefore, this method is employed to save random numbers as “no caller id” to stop you from picking them up when the no caller id calls pop on your phone.

1. Select the “Contacts” icon, then click on the + button to add a new contact on your phone.

You can use these three methods to block and restrict yourself from picking up “No caller id” contacts when using the new iPhone model.

Unfortunately, when you use the old model iPhone, such as iPhone 7, iPhone 6, iPhone 6s, or iPhone 8, they may not have features like the “Silence unknown caller” function.

Perhaps, there are other methods you can use to block and resist the “No caller I.D. callers from your old model iPhone.

2. Save the contact with the name “No caller id.”
