The quickest way to unblock a number on Samsung

To unblock a number on your Samsung phone, open the Phone app, tap the three-dot menu icon (or the menu button), select Settings, then Blocked numbers. Find the number you want to unblock in the list, tap it, and select Unblock. The number will be removed from your blocked list when ready, and calls and texts from that contact will come through again.

The exact steps vary slightly depending on your Samsung model and Android version, but the Phone app is the standard place where Samsung stores your blocked numbers. If you cannot find a Blocked numbers option in your Phone app settings, your phone may be using Google's native blocking system instead — in that case, open Contacts, find the person you want to unblock, tap the three-dot menu, and select Unblock.

Key Takeaways

  • Open the Phone app, tap the menu, go to Settings, then Blocked numbers to see your full list of blocked contacts.
  • Select the number you want to unblock and tap the Unblock button — the change takes effect when ready.
  • If your Phone app does not have a Blocked numbers section, open Contacts instead and unblock from there.
  • Unblocking a number restores calls, text messages, and voicemails from that contact.

Finding your blocked numbers list in the Phone app

The Phone app is where Samsung keeps track of numbers you have blocked. Open it and look for a menu button — on most Samsung phones this is three vertical dots in the upper right corner, though some older models use a horizontal three-line menu icon. Tap it and scroll down until you see Settings.

Once you are in Settings, look for an option called Blocked numbers, Block list, or Blocked contacts. The exact wording depends on your Android version and Samsung interface, but it will be clearly labeled. Tap it and you will see a list of every number you have blocked on this phone.

Unblocking a specific number

Find the number you want to unblock in the list. Tap it once — you should see options appear, including an Unblock button or a trash icon. Tap Unblock (or the trash icon if that is the only option shown). The number will be removed from your blocked list right away.

Once a number is unblocked, that person can call you, send you text messages, and leave voicemails just like any other contact. You will see their calls and messages in your normal call log and message threads. If you want to block them again later, you can do so the same way you blocked them originally — by opening their contact, tapping the menu, and selecting Block.

If your Phone app does not have a blocked numbers section

Some Samsung phones, especially those running newer versions of Android, use Google's blocking system instead of Samsung's own. If you open your Phone app settings and do not see a Blocked numbers option, try this route instead: open your Contacts app and search for the person whose number you want to unblock.

Tap their contact card to open it. Look for a menu button (three dots) in the upper right corner and tap it. You should see an Unblock option in the dropdown menu. Tap it and the number will be unblocked. This method works the same way as unblocking through the Phone app — the change is when ready.

What happens after you unblock a number

Once you unblock a number, that contact can reach you through calls, text messages, and voicemails. You will not receive a notification that they have tried to contact you while they were blocked — blocked calls and messages do not create a record you can see later. The unblocking only affects future contact.

If you unblock a number by mistake, you can block it again using the same steps in reverse. Open the Phone app or Contacts app, find the number, tap the menu, and select Block. There is no limit to how many times you can block and unblock the same number.

Unblocking multiple numbers at once

If you have blocked several numbers and want to unblock more than one, you will need to unblock them individually — Samsung does not offer a way to select multiple blocked numbers and unblock them all at once. Go through your blocked numbers list and tap each one you want to restore, then select Unblock.

If you have a very long list of blocked numbers and want to start fresh, the fastest approach is to go into your Phone app settings, find the Blocked numbers section, and look for a Clear all or Delete all option. Not all Samsung phones offer this, but if yours does, it will unblock every number on your list with one tap.

Frequently Asked Questions

Can I unblock a number if I have deleted their contact?

Yes. Blocked numbers are stored separately from your contacts, so deleting someone's contact does not affect whether they are blocked. Open your Phone app, go to Blocked numbers, find the phone number in the list, and unblock it. You can unblock a number even if you have no record of who it belongs to.

Will the person know I unblocked them?

No. Unblocking a number is silent — the person will not receive any notification that you have unblocked them. They will only know if they try to call or text you and the message goes through, whereas before it was blocked.

What is the difference between blocking and muting a contact?

Blocking stops calls and texts from reaching you at all. Muting (or silencing) a contact still lets their calls and messages through, but your phone will not ring or vibrate when they contact you. You can mute a contact without blocking them by opening their contact card and selecting Mute notifications.

If I unblock a number, will I see old messages from when they were blocked?

No. Messages sent while a number was blocked do not appear in your message threads. Unblocking only affects future contact. Old blocked messages are not recovered or displayed.
