You can see blocked messages on iPhone, but only if you unblock the contact first
When you block someone on iPhone, their messages don't disappear — they move to a separate folder you can access anytime. Apple doesn't delete blocked messages; it just hides them from your main conversation list. If you want to read what a blocked contact sent you, you unblock them temporarily, read the messages, and block them again if you want to.
The catch: unblocking shows the contact that you've unblocked them (they'll see "Delivered" status return on their messages), and you'll see all their messages at once, including ones from before you blocked them. There's no way to view blocked messages without unblocking the contact first.
Key Takeaways
- Blocked messages stay on your iPhone in a hidden conversation thread; they are not deleted when you block someone.
- To read blocked messages, you must unblock the contact in Settings > Messages > Blocked Contacts, then open the conversation.
- Unblocking a contact makes your previous "Do Not Disturb" status visible to them again, and they may notice the change.
- You can block the contact again when ready after reading the messages if you want to resume blocking them.
- iMessage, SMS, and FaceTime calls from blocked contacts all follow the same blocking rule — they hide but don't delete.
Where blocked messages actually live on your iPhone
Blocked messages don't sit in a special "Blocked Messages" folder the way deleted emails sit in Trash. Instead, they stay in the original conversation thread with that contact, but the thread itself is hidden from your main Messages list. The conversation exists; you just can't see it unless you unblock the person.
This means if you blocked someone after exchanging 50 messages with them, all 50 messages are still there. When you unblock them, you'll see the entire conversation history, including messages from years ago. Nothing is lost — it's just out of sight.
How to unblock a contact and see their messages
Open Settings on your iPhone and tap Messages. Scroll down and tap Blocked Contacts. You'll see a list of everyone you've blocked. Find the contact whose messages you want to read, swipe left on their name, and tap Unblock. The contact is now unblocked.
Go back to your Messages app and search for that contact's name, or scroll through your conversation list — their thread will now appear. Tap it to open the conversation and read all their messages, including the ones they sent while they were blocked.
If you want to block them again after reading, go back to their conversation, tap their name at the top, scroll down, and tap Block This Caller. You can block and unblock the same person as many times as you need to.
What the contact sees when you unblock them
When you unblock someone, they don't get a notification that says "You've been unblocked." However, they will notice that their messages are now delivering again. Before you unblocked them, their messages showed "Not Delivered" or sat in a pending state. Once you unblock them, those messages will show "Delivered" and any new messages will come through normally.
If the contact is paying close attention, they may realize you unblocked them based on the delivery status change. There's no way to unblock someone silently — the technical side of messaging will make the change visible to them.
The difference between blocking and muting a conversation
Blocking and muting are two different things, and it's worth knowing the difference. When you block someone, their messages don't come through at all — they can't reach you by iMessage, SMS, or FaceTime. When you mute a conversation, the messages still come through, but you don't get notifications about them. The conversation stays in your list, just silenced.
If you want to see someone's messages without being bothered by notifications, muting is the right choice. Go to the conversation, swipe left on it, and tap the speaker-with-a-slash icon. If you want to block them completely so they can't reach you, that's a different action in Settings.
What happens to blocked FaceTime calls and voicemails
Blocking someone on iPhone blocks iMessage, SMS, and FaceTime calls all at once — it's one block that covers everything. If a blocked contact tries to call you on FaceTime, the call won't go through. If they try to call your phone number, the call goes to voicemail, but they won't hear a "number is blocked" message; it will just ring once and go to voicemail.
Voicemails from blocked contacts still arrive on your iPhone, but they go to a separate section in the Phone app called Blocked Messages. You can listen to them the same way you listen to regular voicemails, but they're grouped separately. Like text messages, voicemails from blocked contacts are not deleted — they're just organized away from your main voicemail list.
Why you might want to keep blocked messages unread
Some people block a contact but want to know if they ever try to reach them again. In that case, you can unblock the contact temporarily, check if there are new messages, and block them again without reading anything. This way you know they contacted you, but you're not engaging with the messages themselves.
Others block a contact but later change their mind and want to read what they missed. Unblocking lets you do that without losing any of the message history. The messages are always there; blocking just hides them from view.
Frequently Asked Questions
Do blocked messages get deleted when I block someone?
No. Blocking hides the conversation from your main list, but all messages stay on your iPhone. When you unblock the contact, you'll see the entire conversation history, including messages from before you blocked them.
Can I see blocked messages without unblocking the contact?
No. There is no way to view blocked messages on iPhone without unblocking the contact first. Once you unblock them, the conversation becomes visible in your Messages app.
If I unblock someone, will they know?
They won't get a notification, but they may notice that their messages are now delivering again instead of showing "Not Delivered." The delivery status change can tip them off that you've unblocked them.
What's the difference between blocking and muting?
Blocking stops messages and calls from reaching you at all. Muting lets messages come through, but you don't get notifications about them. The conversation stays visible in your list, just silenced.
Are blocked voicemails deleted?
No. Voicemails from blocked contacts go to a separate Blocked Messages section in the Phone app, but they're not deleted. You can listen to them anytime by opening that section.
