To unblock someone on iMessage, open the Settings app, tap Phone, then Blocked Contacts, and swipe left on the person’s name to tap Unblock. This is the most reliable way to restore messages and calls from a contact you previously blocked, and it also works for FaceTime and Mail.
How to unblock someone on iMessage from your iPhone settings
The Settings app gives you a complete list of every number and contact you have blocked, making it the primary method to manage blocks in one place. You can unblock someone on iMessage here even if you no longer have an active conversation with them, which is useful when you want to clear out old blocks or reconnect with someone after a long time.
- Open the Settings app on your iPhone.
- Tap Phone.
- Scroll down and tap Blocked Contacts. On earlier iOS versions, this option might be labeled Call Blocking & Identification.
- You will see a list of your currently blocked numbers and contacts. Find the person you want to unblock.
- Tap the red circle with a line in the center next to the number, then tap Unblock.
Alternatively, you can swipe left on the entry for the number or contact you wish to unblock, and a red Unblock option will appear. Tap it, and the number is removed from the blocked list immediately. This swipe shortcut is faster when you know exactly who you are looking for, and it saves you an extra tap compared to the circle method.
How to unblock a contact from an iMessage conversation
If you still have the old chat thread with the person, you can unblock them directly from that conversation without leaving the Messages app. This method is handy when you want to unblock someone on iMessage right after seeing their name in your chat list, and it avoids navigating through multiple Settings menus.
- Open the Messages app and tap the conversation with the person you want to unblock.
- Tap the "i" icon to the right of the number at the top of the conversation.
- Scroll down and tap Unblock Caller.
Once you tap Unblock Caller, the block is lifted instantly. You do not need to confirm the action, and the contact will not receive any notification that you have unblocked them. If you do not see the Unblock Caller option, it means the contact is not currently blocked, so you can simply close the profile and continue messaging normally.
What happens when you unblock a contact
Unblocking a contact restores communication across all Apple services, not just iMessage. Blocking and unblocking a contact applies across Phone calls, Messages (iMessage and SMS/MMS), FaceTime, and Mail, so after you unblock someone on iMessage, they can reach you through any of these channels again. The contact is not notified when you unblock them, so there is no awkward alert on their end, their messages and calls simply start coming through as if the block never existed.
Keep in mind that unblocking does not automatically add the person back to your Contacts app. If you deleted their contact information while they were blocked, you will need to save it manually to see their name instead of just a phone number. Also, any messages they sent while blocked will not appear retroactively; you will only see new messages sent after the unblock.
Why isn't iMessage working after I unblock someone?
If you have unblocked someone on iMessage but still cannot send or receive messages from them, the issue is likely with iMessage activation rather than the block itself. First, check that your device has the latest version of iOS installed, as outdated software can cause messaging glitches. Next, confirm that you are connected to a cellular data or Wi-Fi network, because iMessage requires an active internet connection to send and receive blue bubbles.
Your time zone settings also matter, if your iPhone’s time zone is incorrect, iMessage may fail to activate properly. Go to Settings > General > Date & Time and ensure “Set Automatically” is turned on. If you are using an iPhone, you need SMS messaging to activate your phone number with iMessage and FaceTime; contact your carrier to ensure you can receive SMS messages, since some carriers block SMS on certain plans.
If your iMessage account was deactivated or blocked due to spam reports, unblocking a contact will not fix that. In that case, you need to contact Apple Support directly to review your account and help reactivate Messages. This is a separate issue from a contact block, and only Apple can restore your iMessage service after a spam-related suspension.
