It is quite unpleasant to frequently get calls from unknown numbers. When you’re in a meeting, asleep, or taking a shower you keep on getting that bothersome telemarketing or debt recovery call that keeps coming mistakenly.

We are aware that these calls are annoying, interfere with our ability to complete tasks, frighten us, and tempt us to smash our phones against the wall. Have you ever considered that this issue might have a solution? Let’s get to work on figuring out how to block unknown calls on iPhone.

1. Silencing a Number on an iPhone

Let’s understand how to restrict a phone number first so we can start our quest to stop obnoxious calls. Keep in mind that you can register your phone number with the Nationwide Do Not Call Directory. If you get an obnoxious call after your contact has been officially listed for about 31 days, you can immediately report it.

The guilty company will be punished. However, not all bothersome callers are telemarketers. You may also be required to block a mobile number if you frequently receive calls from it to protect your sanity. When iOS 13 was introduced, Apple gave users of the iPhone a practical option to prevent unauthorized and unwanted calls. 

Only calls from mobile numbers recorded in the Contact list, Mail, and Messages app will be accepted by Siri, the artificial intelligence assistant on the iPhone. The calls involving unknown sources are recorded in a list that you can view to verify the numbers and answer those which seem important.

1. First, go to the Settings app on your smartphone, then scroll down to Phone to enable this option.
2. After that, select Silence Unknown Callers and activate it by tapping the bar.

There you go! The only calls you’ll receive from now on will be from the contacts you’ve added, though you can still check the list for any others. 

2. Do Not Disturb Option

You can still prevent unauthorized calls if you are unable or unwilling to switch to iOS 13. Put Do Not Disturb on a 24-hour schedule, and only allow calls from people you know. Remember that you won’t receive any call from a person who is not on your contact list if they call you.

However, you can still listen to voicemails left by blocked calls. A second phone call from the same individual within three minutes can be allowed as well, ensuring that you can be contacted in an emergency.

The Do Not Disturb technique, like the Silence Unidentified Callers technique, will prevent all calls marked “No Caller Identity,” even if the caller is one of your contacts.

Follow these steps to use the do not disturb option:

1. Unlock your phone and select Settings.
2. Next, navigate to the menu and select the icon for Do Not Disturb.
3. Select Allow Calls From option and then select All Contacts.
4. Shut down the settings and go back to the home screen.

3. How To Block Undesired Numbers On An iPhone 

You can block undesired numbers from voicemails or calls you’ve recently received.

• After viewing the contact’s card by tapping the information icon, tap the button that says “Block this caller.”
• Go to Settings, tap Phone, then Blocked contacts to edit the contacts that have been blocked.

You’ll find a list of everyone who has been blocked there, indicating they are no longer permitted to call you or text you in any form.

4. Phone Call Management Applications

Now, if you require a little further assistance with managing your incoming calls and the tools that the iPhone has to block unidentified calls are insufficient, there are other applications with the same objective that are now available and offer other more sophisticated features to handle the work.

Here, we’ve compiled a list of the most popular and useful iPhone call management and blocking apps.

4.1. Truecaller

The first alternative among the additional apps for blocking obnoxious calls is Truecaller. It is the most well-known application because, in addition to blocking all spam calls, it also allows you to view further information about the number, for example, the contact’s name.

4.2. Whoscall

Whoscall is a very flexible program that can be used to reject spam calls. It is free, available in 31 countries, and works on iPhone, Android, and even Windows. The app does an incredible job of recognizing and blocking numbers for you.

The software provides a far more complete solution for the security of your cellphone and includes a call-blocking feature. There are many features available in both the paid and free versions of it.

5. How to Set Up an iPhone Call Management App

You’ll need to make a few changes to your phone’s settings before you can use third-party software to block unsolicited calls.

1. Launch the Settings app.
2. Tap on Phone after scrolling down to it.
3. Press the option of Call Blocking & Identification. Keep in mind that this choice might only be available after a call-blocking application has been downloaded and set up.
4. Select Call Identification Apps and activate call blocking.

6. Creating a New Contact To Prevent Unwanted Calls

Adding a new contact with the name “Do Not Answer” or “No Caller ID” to your phone’s contacts list is another technique to block unknown callers. Unfortunately, as it cannot recognize them, your iPhone cannot ban hidden or private numbers.

However, you can get around this by making a contact that looks just like this fictitious number.

1. For adding a new contact, go to Contacts and hit the Plus symbol.
2. In the space provided for the contact’s name, type “No Caller ID.”
3. Then, enter “000-000-0000” for the new contact’s phone number.
4. To save, click Finish.
5. Then, navigate through the profile of this recently added contact until you find the option to Block this Caller, and tap on it.
6. To confirm your selection, click Block Contact.

Your phone will now identify any secret or private phone numbers as blocked numbers and stop your device from ringing if you get a call from an unidentified number.

7. Unblocking a Number on an iPhone

Don’t worry if you’ve been overly aggressive with your call blocking; it occurs. Following are instructions concerning how to enable a blocked number:

1. Launch the Settings app.

3. You may view a list of all the phone numbers you’ve blocked by tapping Blocked Contacts.
4. Select Edit from the menu in the top right corner of the screen.
5. A number can be eliminated from the list by tapping the red circular minus symbol.
6. Next, select Unblock.
