How to Block Spam Calls on iPhone [2024 Updated]

Part 1: What Are Spam Calls and Why Do I Get Them?

Spam calls are unsolicited calls that are typically used for advertising, scams, or other unwanted purposes. You might receive spam calls for various reasons, such as your phone number being leaked in a data breach, listed on public directories, or even generated randomly by automated systems.

Spam callers often use tactics like robocalls—automated calls that play pre-recorded messages—or even "No Caller ID" numbers to trick you into answering. That’s why we will learn how to block spam calls on iPhone free. Scammers may also use local numbers that appear familiar to make you more likely to pick up the phone, a technique known as "neighbor spoofing."

Part 2: 5 Methods to Block Spam Calls on iPhone

Method 1: Use the Silence Unknown Callers Feature

One of the simplest ways to stop spam calls is by enabling the Silence Unknown Callers feature. This option automatically silences any call from a number that isn’t in your contacts, sending it directly to voicemail. You won’t even hear your phone ring, making it an excellent solution for people who don’t want to be bothered by unknown numbers.

Here is how to block spam calls on iPhone app:

• Open the Settings app on your iPhone.
• Tap Phone.
• Tap Silence Unknown Callers.

• Move the Silence Unknown Callers slider to the “on” or green position.

Once activated, calls from any unknown number will be sent to voicemail without ringing. You can also use a guide about how to block spam calls on iPhone #662#, which is simple. All you have to do is dial #663#.

Method 2: Use Do Not Disturb Mode

Do Not Disturb mode is a versatile feature that can be customized to block spam calls while still allowing important calls from people in your contacts to come through. By tweaking a few settings, you can silence calls from anyone who isn’t saved in your phone's address book.

Here’s how to block spam calls on iPhone 13:

• Open the Settings app on your iPhone.
• Tap Focus, then tap Do Not Disturb.

• Toggle the Do Not Disturb slider to the “on” or green position.


• In the Allowed Notifications section, tap People.
• Under the Also Allow section, select Calls From and tap All Contacts or Contacts Only.

Method 3: Block No Caller ID Calls Using a Fake Contact

One of the most common tricks used by spammers is to hide their caller ID information, making it harder to identify whether the call is worth answering. Luckily, there’s a workaround that allows you to block all No Caller ID calls by creating a fake contact and blocking it.

Here is how to stop unknown calls on iPhone:

• Open the Contacts app and tap the + (Plus) button to create a new contact.
• In the First Name field, type “No Caller ID.”
• Tap Add Phone, and enter "000 000 0000" as the phone number.

• Tap Done to save this fake contact.



Next, block this contact to send any No Caller ID calls straight to voicemail:

• Go to the Settings app on your iPhone.
• Tap Phone, then tap Blocked Contacts.

• Scroll to the bottom of the list and tap Add New.



• Find and tap the “No Caller ID” contact you just created.

This method ensures that any call with no caller ID information will automatically be blocked, which is a common hallmark of spam calls.

Method 4: Block Spam Calls Manually

If you occasionally receive calls from the same spam numbers, manually blocking them can be a good solution. This method allows you to block specific numbers that have called you before. Here’s how:

• Open the Phone app and go to the Recents tab.

• Find the spam call you want to block and tap the i (info) icon next to the number.


• Scroll down and tap Block this Caller.

• Confirm the action by tapping Block Contact.

This method is particularly useful for blocking persistent spam numbers. However, keep in mind that spammers often use different numbers, so you may still get some unwanted calls from new numbers that haven’t been blocked yet.
