How to Block and Unblock Someone on iMessage (Update iOS 15)

I composed this guide to help you understand a way you can block (or unblock) someone through iMessage on iPhones, iPads, and Mac computers. Case in point: you don’t have to put up with any text on iMessage that you don’t want to.

How to block someone on iMessage

Hello everyone! It is your good friend Frankie – the renowned messaging app and ethical hacking technique expert. Welcome all to my blog.

Today I want to talk with you about some of the tips you might want to manage certain contacts or unsaved numbers on your iPhone. If you have someone repeatedly annoying you with messages ad calls, I have the answer for you. This guide will show you how to block someone on iMessage, and how to reverse this process if you later change your mind.

If you are not completely familiar with iMessage, this is the instant messages service that accompanies Apple devices, allowing users to text, send pictures, send videos and locate other iMessage users. It is one of the most popular IM services in US now, as you can register through your email or phone number to use it.

Even with the simplicity of use, there are times where you are going to want to block someone else from contacting you.

Fortunately, this is easy to do, and I can show you how.

So let’s get down to it!

Block Someone with iMessage on Your iPhone or iPad

Before we get into the steps necessary to block someone on iMessage, you need to know how this blocking actually works:

Let’s get back to it.

How To Block Someone on iMessage

Here is what you need to do to block someone on iMessage:

  1. Launch the messages app on your iPhone (or iPad if you prefer).Block someone on iMessage - step 1
  2. Open the conversation with the contact you wish to block.Block someone on iMessage - step 2
  3. Click the number or contact image at the top of this page.Block someone on iMessage - step 3
  4. Tap on Info.Block someone on iMessage - step 4
  5. Click to Block this Caller, and then confirm by tapping again to Block Contact in the popup menu that appears.Block someone on iMessage - step 5

Easier than you thought, right?

NOTE: Messages sent or received will not be delivered.


Frankie’s Take:

Maybe you don’t want to go to the extent of blocking someone on iMessage. You can mute conversations from this contact through iMessage. You would start by launching Messages and then swiping left on a conversation you want to mute and click on the bell icon that is crossed out. For more information on this approach, check out a guide I wrote on muting notifications from the Messages app.

Filter Messages from Unknown Senders Coming to Your iPhone

Few people seem to know that you can filter messages incoming from numbers not in your contact list. I am going to share this trick because I think it is quite useful.

By activating to Filter Unknown Senders, the Messages app will filter messages. Now you will only receive texts from numbers stored in your device.

Here is how you activate this feature:

  1. Launch Settings on your iPhoneFilter Messages from Unknown Senders - step 1
  2. Scroll down and tap MessagesFilter Messages from Unknown Senders - step 2
  3. Turn on the feature to Filter Unknown SendersFilter Messages from Unknown Senders - step 3

If you want to see this content for some reason, you can open Messages and then tap on the Filters in the top left corner and choose Unknown Senders to see what has arrived.

NOTE: This window will only be there if you have your phone set to filter out this content.


Frankie’s Take:

If you are not satisfied with blocking or filtering content from unknown contacts, you can also report a number or contact as Junk or Spam for investigation.

Block Texts in the Messages App on Mac (macOS Big Sure Update)

If you have a Mac (like I do) and use Messages, you can block someone through this service as well.

Let me show you how to do this:

  1. Launch Messages on your Mac and select the conversation for the contact or number you want to block
  2. Click Conversations in the menu bar and then choose Block Person
  3. Confirm by tapping Block in the pop-up option appearing

Unblock a Number on Your iPhone

If you change your mind, or blocked someone by accident, you can easily unblock someone in just a few steps. These are:

  1. Open Settings on your iPhone
  2. Tap Messages
  3. Choose Blocked Contacts. Then tap on the contact you want to unblock, slide left, and tap to Unblock


What Happens When Someone Is Blocked From My iMessage?

Messages that are sent or received will not be delivered if one of the contacts is blocked. They can still receive voicemail from you, but you will no longer be alerted.

Can You Remove the Contact Itself and Block A Number?

As of right now, this is not a possibility. You have to still call your carrier to completely block a number. Some offer an option to login to an account through a carrier portal and add a number to a blacklist for your phone service. This might take a while to take effect, though.


Hopefully the information provided here has helped you.

I wanted to not waste your time and give you the most concise information possible. Now you know how to block incoming text messages on your iPhone and even unblock these if you change your mind.
