Wondering why you are not getting texts or calls from a particular person? There is a chance you might have blocked them accidentally. It’s one of the most common mistakes people make. Sometimes, the anti-spam feature in a phone may also block specific contact to prevent data breaches and improve the phone’s security. 

Blocking a mobile number on an iPhone is a way to prevent incoming calls, text messages, and other communications from that number from reaching your phone. You can block a mobile number on an iPhone in a few different ways.

In this article, I will talk about the iPhone’s anti-spam feature in detail. We will also discuss what happens if you block or unblock a contact on your phone. Let’s get going. 


Can You Accidentally Block A Number on an iPhone?

It is possible to accidentally block a number on an iPhone if you are not careful. There are several ways to block a number on an iPhone, including using the Phone app or the Settings app.

In the Phone app, you can block a number by going to the Recent tab and swiping left on the number you want to block. It will bring up the option to Block the number. If you accidentally tap on this option, the number will be blocked.

In the Settings app, you can block a number by going to Phone and then tapping on the Blocked Contacts option. From here, you can tap the Add New button to enter the number you want to block or select it from your contact list. The number will be blocked if you accidentally tap on the Block button.


How to Unblock A Number on iPhone 

If you have blocked a phone number on your iPhone, you can unblock it at any time by following these steps:

  • Launch the Settings app by tapping the gear icon on your iPhone.
  • Scroll down and tap on the Phone.
  • Tap on the Call Blocking & Identification option.
  • Here you can see the list of all the phone numbers that you have blocked in the past..
  • Tap on the Edit button in the top right corner.
  • Tap the red circle next to the phone number you want to unblock.
  • Tap on the Unblock button that appears.


What Happens After Unblocking A Number on iPhone?

✔ The phone number will be removed from your blocked list: When you unblock a phone number, it will be removed from the list of blocked numbers in your iPhone’s settings. It means that calls and messages from this number will no longer be stopped, and you will receive them as usual.

✔ You will be able to call and message the phone number: Once you have unblocked a phone number, you will be able to call and message it just like any other phone number. It includes using features such as FaceTime, iMessage, and voicemail.

✔ The phone number may still be blocked by other apps: Unblocking a phone number in your iPhone’s settings only affects the built-in phone and messaging apps. If you have blocked a phone number in other apps, such as WhatsApp or Facebook Messenger, you need to unblock it separately.

✔ You may still have a blocked caller’s information in your contacts: If you have the phone number saved in your contacts, the blocked caller’s data will still be stored in your contacts. However, you can call and message them again once you have unblocked the number.


What is the iPhone Anti-spam Feature?

The iPhone has an anti-spam feature that helps to protect you from unwanted calls and texts. This feature uses algorithms and other techniques to identify and block spam calls and texts.

To enable the anti-spam feature on your iPhone, go to the Settings app and tap Phone. From here, you can toggle on the Silence Unknown Callers option. It will block incoming calls from numbers not on your contact list.

You can also block specific numbers or contacts by going to the Blocked Contacts option in the Phone settings. From here, you can tap the Add New button to enter the number or contact you want to block.

In addition to blocking calls and texts, the anti-spam feature on the iPhone also includes a spam reporting feature. If you receive a spam call or text, you can report it by tapping the Report Junk option in the call or message thread. It helps improve the anti-spam feature’s accuracy and protect others from similar spam calls and texts.

Overall, the anti-spam feature on the iPhone is a valuable tool for protecting you from unwanted calls and texts. By enabling this feature and reporting spam calls and texts, you can improve the accuracy of the feature and reduce the amount of spam you receive.



In summary, unblocking a phone number on your iPhone will allow you to receive calls and messages from that number again and remove the number from your blocked list. However, it is essential to note that unblocking a phone number does not automatically erase any information about the caller from your phone or delete any previous conversations.
