How To Unblock Someone On Messages | Fix The Block List

You blocked someone for a reason. Then life changes. Maybe it was a wrong tap, maybe it was a spam wave, maybe you just want the conversation back.

Unblocking on “Messages” can mean a few different things, depending on your phone. On iPhone, blocking is tied to your Apple ID and the system blocked list. On Android, it depends on which Messages app you use (Google Messages, Samsung Messages, carrier apps).

This walkthrough covers the common setups and the sneaky cases where a person still can’t text you even after you think you unblocked them.

Before You Unblock, Check What “Blocked” Means On Your Phone

Most people expect a block to work the same way everywhere. It doesn’t. A “block” can live in more than one place.

• Messages app block: Stops texts from that sender inside the messaging app.
• System blocked list: A shared list used by Phone, FaceTime, and Messages on iPhone.
• Spam filter: Messages may be allowed but shoved into a spam or filtered folder.
• Carrier-level block: Blocks handled by your mobile provider or a carrier add-on.
• Third-party call/text blocker: Apps that block numbers outside the Messages app.

So the goal is simple: remove the person from the list that’s actually blocking them.

How To Unblock Someone On Messages On iPhone

On iPhone, blocking is centralized. If you unblock from the blocked list, it affects Messages, calls, and FaceTime for that contact or number.

Method 1: Unblock In Settings

This is the most reliable route because it targets the system list directly.

1. Open Settings.
2. Scroll down and tap Privacy & Security (on many iOS versions), then tap Blocked Contacts.
3. Find the person or number you want to restore.
4. Tap Edit, then remove them from the blocked list and confirm Unblock.

If your iPhone menus look a bit different, that’s normal. Apple moves settings between iOS versions. The underlying idea stays the same: you’re removing the entry from Blocked Contacts. Apple’s steps for managing blocked contacts are shown on Apple’s “Block contacts” instructions.

Method 2: Unblock From A Conversation Thread

If you still see the thread (or an old thread) from that person, you can often unblock from the contact card.

1. Open Messages.
2. Tap the conversation with the person (or open their contact card from another app, like Phone).
3. Tap the name/number at the top to open details.
4. Scroll until you see an option like Unblock or the block toggle, then switch it off.

If you don’t see the option in Messages, use the Settings method above. It works even if the thread is deleted.

After Unblocking On iPhone, What Changes Right Away

• New texts from that number can arrive again.
• Old messages that were blocked usually won’t “reappear.” They were never delivered while blocked.
• If the sender is using iMessage, delivery can switch back to iMessage once both sides are online.

How To Unblock Someone On Messages On Android

Android is a bigger maze because “Messages” can mean different apps. Start by confirming which one you use. Look at the app icon and the name on your home screen.

Google Messages (Most Common On Android)

Google Messages keeps blocked senders under a spam and blocked area.

1. Open Messages (Google Messages).
2. Tap your profile icon (top right) or the three-dot menu (top corner, varies by version).
3. Open Spam & blocked.
4. Tap the blocked conversation, then tap Unblock.

If you want the official navigation steps, Google documents the unblock flow in Google Messages “Block senders & report spam”.

Samsung Messages

Samsung’s Messages app usually stores blocked numbers under its own settings.

1. Open Samsung Messages.
2. Tap the menu (three dots).
3. Tap Settings.
4. Look for Block numbers and messages or Blocked numbers.
5. Remove the number from the blocked list.

Menu names can differ by model and One UI version. If you can’t find the block list inside Samsung Messages, try the Phone app’s blocked numbers list as well, since some devices share a blocking list across calls and texts.

Android Phone App Blocking Can Also Affect Texts

On many Android phones, blocking a number in the Phone app can block calls and texts together.

If you unblocked in Messages but texts still don’t arrive, check the Phone app’s blocked list too:

1. Open the Phone app.
2. Open the menu, then Settings.
3. Find Blocked numbers.
4. Remove the number.

Where Unblock Settings Live On Common Devices

Use this table as a quick map when you’re not sure where the block is stored. If your phone looks different, follow the closest match and search inside Settings for “blocked” to jump to the right screen.

Device Or App	Where To Unblock	What To Watch For
iPhone (iOS)	Settings → Privacy & Security → Blocked Contacts	Unblocking here affects Messages, Phone, FaceTime
iPhone (alternate menu)	Settings → Messages (or Phone) → Blocked Contacts	Menu names shift across iOS versions
Google Messages	Profile/Menu → Spam & blocked → Select sender → Unblock	Spam filtering can hide messages even without a block
Samsung Messages	Menu → Settings → Block numbers / Blocked numbers	Some models also block via the Phone app list
Android Phone app list	Phone → Menu → Settings → Blocked numbers	May block calls and texts together on some phones
Carrier spam add-ons	Carrier account settings or carrier app	Blocks can persist even if you unblock in Messages
Third-party blockers	Inside the blocker app settings	App can keep blocking even after you unblock elsewhere
Kids/Work profiles	Device management app or profile settings	Restrictions can block texts without showing a normal list

Why You Still Aren’t Getting Texts After Unblocking

Unblocking is often instant. When it isn’t, the issue is usually one of these. Work down the list and you’ll usually find the culprit.

They’re Being Filtered, Not Blocked

Some apps separate messages from unknown senders or suspected spam. That can feel like a block.

• On iPhone, check the Messages list filters and any “unknown” or filtered views.
• On Google Messages, check Spam & blocked even if you didn’t block them on purpose.

If the message is sitting in a filtered area, moving it back to your main inbox often fixes future delivery too.

You Unblocked A Contact, But They Text From Another Number

This happens a lot with:

• Dual SIM phones
• Business lines and personal lines
• iMessage email vs phone number (on Apple devices)

On iPhone, a person can reach you via their phone number or an email tied to iMessage. If you blocked the email and only unblocked the phone number (or the other way around), the block can still hit.

Scan your blocked list for any duplicate entries that look like the same person.

Your Phone Is Still Syncing Or Cached

Sometimes the setting flips, but the messaging app is holding an old state for a moment.

• Close the Messages app and reopen it.
• Turn Airplane mode on, wait 10 seconds, then turn it off.
• Restart the phone if the thread still looks locked.

This sounds basic, but it clears the tiny stuck states that keep a thread from behaving normally.

RCS Or iMessage Needs A Fresh Handshake

Modern messaging uses extra layers beyond SMS.

• iMessage: Delivery depends on Apple’s network and the sender’s Apple ID route.
• RCS: Delivery depends on your data connection and the RCS status of both lines.

If you unblock and still don’t see messages, ask the sender to send one new message after a minute or two. That new send often refreshes the route.

It’s A Carrier Block, Not A Phone Block

If you ever used carrier spam controls or blocking tools, those can override your phone’s app settings. Carrier blocks can also catch short codes and business senders.

Clues you’re dealing with a carrier-level block:

• You can receive messages over Wi-Fi apps but not SMS
• Only one specific sender type fails, like bank codes or delivery alerts
• The issue follows you even after you switch messaging apps

In that case, check your carrier settings or disable the blocking add-on in the carrier app, then test again.

Fix Checklist When Unblocking Doesn’t Work

If you want the fastest path, follow these steps in order. Each one removes a common failure point without wasting time.

1. Confirm you removed the person from the correct blocked list (system list on iPhone, app list on Android).
2. Check spam/filtered folders inside your Messages app.
3. Check for a second entry for the same person (email vs number, second SIM, old number).
4. Restart Messages, then restart the phone if needed.
5. Ask the sender to text again after a minute.
6. Try sending them a message from your side to confirm the thread opens normally.
7. If SMS still fails, check carrier blocking tools and any third-party blocker apps.

Common Unblock Problems And What Fixes Them

This table is for the cases that feel confusing: you did unblock them, but the behavior still looks blocked.

What You Notice	Likely Cause	What To Do Next
You can’t see new texts, but calls come through	Messages app filter or spam folder	Check “Spam & blocked” (Android) or filtered views (iPhone)
Texts arrive from some people, not one person	You unblocked the wrong entry	Unblock both the phone number and any iMessage email tied to them
Only verification codes don’t arrive	Short code or business sender block at carrier level	Review carrier blocking tools and message filtering settings
Messages show up hours late	RCS/iMessage routing delay or poor data	Toggle Airplane mode, confirm data/Wi-Fi, ask sender to resend
You unblocked, but the thread still looks “locked”	App cached state	Force close Messages, reopen, then restart the phone
Unblocking in one app changes nothing	Second block list exists (Phone app, third-party blocker)	Check Phone app blocked numbers and any blocking apps
It works on Wi-Fi chat apps but not SMS	Carrier-level issue	Check carrier settings, confirm you can send/receive SMS in general

Clean Up Your Block List So This Doesn’t Happen Again

Most block lists grow quietly over time. You block a spammer, then a weird number, then a business sender you didn’t recognize, then you forget it’s there.

A quick cleanup once in a while makes unblocking simpler later.

Do A Quick Scan For Duplicates

• Look for the same person listed twice with slightly different formats.
• On iPhone, look for both phone numbers and email addresses.
• On Android, look for the same number saved under two contacts.

Save The Contact Before You Test

Saving the sender as a contact can reduce filtering, especially when your phone is cautious with unknown senders. It also helps you spot whether you unblocked the right identity.

Send A Test Message The Right Way

After you unblock, test with a clean, simple message. A single “Hi” works.

• If your message sends but you don’t receive a reply, ask the other person to send one back.
• If both send and receive work, you’re done.
• If sending works but receiving doesn’t, re-check spam folders and carrier filters.

Quick One-Page Unblock Checklist

If you want a simple routine you can follow every time, use this:

1. Unblock in the system list (iPhone) or app list (Android).
2. Check spam/filtered sections in Messages.
3. Look for a second entry (email vs number, second SIM).
4. Close and reopen Messages.
5. Toggle Airplane mode once.
6. Ask for one new incoming text to confirm it’s flowing again.

Once you can receive a new message from that sender, the block is truly gone.
