Unblocking a contact means removing the restriction you placed on someone, so their calls, texts, and messages can reach you again

When you block a contact, your phone or computer stops that person's calls, text messages, and app notifications from getting through to you. Unblocking reverses that — it removes the barrier and lets their communication come through normally. The person you unblocked won't be notified that you've done it, and they won't see any record of the block on their end.

The steps to unblock someone depend on what device you use and which app or service you're unblocking them from. A contact blocked in your phone's native messaging app is different from someone blocked on Facebook or in iMessage. This guide covers the most common places people block contacts and how to undo it.

Key Takeaways

  • Unblocking a contact removes the restriction you set, allowing their calls, texts, and messages to reach you again.
  • The steps differ by device and app — blocking someone in your phone's contacts app is not the same as blocking them on social media.
  • On most phones, you access blocked contacts through Settings, then find the blocking or privacy section specific to your device.
  • The person you unblock will not be notified and will not see any sign that you had blocked them.
  • If you unblock someone and then block them again, previous messages they sent while blocked will not reappear.

Unblocking on iPhone

On an iPhone, blocked contacts are managed in the Settings app. Open Settings, scroll down, and tap Phone. Then tap Blocked Contacts — you'll see a list of everyone you've blocked through the phone app. Swipe left on the person's name and tap Unblock, or tap Edit in the top left, select the contact, and tap Unblock.

If you blocked someone in iMessage instead of the phone app, the process is slightly different. Open the Messages app, find the conversation with the blocked person, swipe left on their name, and tap Unblock. You can also go to Settings, scroll to Messages, tap Blocked Contacts, swipe left on a name, and tap Unblock.

For FaceTime blocks, open FaceTime, find the person in your recent calls or contacts, swipe left on their name, and tap Unblock. Alternatively, go to Settings, tap FaceTime, scroll to Blocked Contacts, and swipe left to unblock.

Unblocking on Android

Android phones vary by manufacturer, but the general path is similar. Open Settings, look for Apps or process Manager, and find your phone or messaging app. Tap it, then look for a menu option — often three dots in the corner — and select Blocked Numbers or Blocked Contacts. Find the person you want to unblock and tap Unblock or Remove.

If you're using Google Messages (the default messaging app on many Android phones), open the app, tap the three-line menu at the top left, go to Settings, tap Blocked, and find the contact. Tap the X or trash icon next to their name to unblock them.

For Samsung phones specifically, open the Phone app, tap the three dots at the top right, go to Settings, tap Block List, and find the contact. Tap Edit or the minus sign next to their name to unblock them.

Unblocking on Social Media and Messaging Apps

Blocking on Facebook, Instagram, WhatsApp, and Telegram is separate from your phone's native blocking. On Facebook, go to Settings, tap Blocking, and you'll see a list of blocked people. Tap Unblock next to the person's name. On Instagram, go to Settings, tap Blocked Users, find the person, and tap Unblock.

In WhatsApp, open the app, go to Settings, tap Privacy, then Blocked Contacts. Swipe left on the person's name (iPhone) or long-press it (Android) and tap Unblock. On Telegram, go to Settings, tap Privacy and Security, tap Blocked Users, find the contact, and tap Unblock.

These app-level blocks are independent of your phone's system-level blocks. You can block someone in your phone's contacts but not in WhatsApp, or vice versa. Each service maintains its own list.

What Happens After You Unblock Someone

Once you unblock a contact, they can call, text, or message you normally. However, messages they sent while they were blocked will not suddenly appear in your conversation history — those are typically deleted or remain hidden depending on your device. If they sent you 10 texts while blocked, you won't see those 10 texts after you unblock them.

The person you unblocked will not receive a notification that you've unblocked them. They won't know you had blocked them in the first place unless you tell them. If they try to contact you while blocked, they may see an error or their message may fail to send, but they won't get a message saying "you are blocked."

If you unblock someone and then decide to block them again later, you start fresh — the block list doesn't retain a history of previous blocks.

If You Can't Find Your Blocked Contacts List

The location of blocked contacts varies by phone model and operating system version. If you can't find it in Settings, try searching "blocked" in your phone's Settings search bar — most phones have a search function at the top of Settings that will take you directly to the right page.

If you're using an older version of Android or iOS, the menu structure may be different. Check your phone manufacturer's support website or search for "[your phone model] how to unblock a contact" to find the exact steps for your device.

Some carriers (like Verizon or AT&T) also offer their own blocking services separate from your phone's built-in blocking. If you blocked someone through your carrier's app or website, you'll need to unblock them there instead.

Frequently Asked Questions

Will the person know I unblocked them?

No. Unblocking someone does not send them a notification, and they won't see any indication that you had blocked them. They will only know if you tell them or if they notice they can reach you again after previously being unable to.

Can I unblock someone and then see the messages they sent while blocked?

No. Messages sent while someone was blocked are not stored or recovered when you unblock them. Those messages are gone. If you want to see what they tried to send you, you would need to ask them directly.

What's the difference between blocking on my phone and blocking in an app?

Blocking on your phone (through Settings) blocks calls and texts at the system level. Blocking in an app like WhatsApp or Facebook only blocks them within that app. You can block someone on your phone but still receive their messages in WhatsApp, or vice versa.

If I unblock someone, will they be able to see my old messages to them?

Yes. Unblocking only affects their ability to reach you going forward. Any messages you sent them before the block are still visible on their phone. Unblocking does not delete your message history from their device.

Can I block and unblock someone multiple times?

Yes. You can block and unblock the same person as many times as you want. Each time you block them, it's a fresh block with no memory of previous blocks. Each time you unblock them, they can contact you normally again.
