Viber Blocked Messages: What Happens and How to Unblock

Posted on 09/11/26 03:13 pm

When you block someone on Viber, their messages and calls stop reaching you and are not saved for later. Here is how blocking works and how to undo it.

What blocking does on Viber

Blocking a contact on Viber stops their messages and calls from arriving on your device. Messages sent while they are blocked are not stored and delivered later, so unblocking does not bring them back. The other person is not sent a notification that you blocked them.

When someone is blockedWhat happens
They send you a messageIt does not reach you and is not delivered later
They call you on ViberThe call does not come through
They are in a group with youGroup messages may still be visible, because blocking mainly affects one-to-one contact
You unblock themNew messages arrive again; old ones stay lost

How to block or unblock

  1. Open Viber and go to More › Settings › Privacy.
  2. Tap Block list to see everyone you have blocked.
  3. Tap a name and choose Unblock, or use the add option to block a number.
  4. You can also block or unblock from a chat: open the chat, tap the name at the top and choose the option.

Menu names can change slightly between Android and iPhone versions, but the block list is always under privacy settings.

Signs someone may have blocked you

  • Your messages stay on one tick and never show as delivered.
  • Calls do not connect.
  • You no longer see changes to their photo or online status.

None of these proves a block on its own: they also happen when someone uninstalls Viber, loses signal or hides their status in privacy settings.

Blocking unknown numbers and spam

Viber can filter messages from people who are not in your contacts into a separate folder, and you can report spam from the chat menu. Reporting helps Viber remove accounts that send bulk messages, which is better than blocking spammers one at a time.

Changing your number instead

If one person keeps contacting you from new numbers, blocking each one becomes tiring. Moving your Viber account to a new number keeps your chats while dropping the old number. See how to change your number on Viber.

FAQ

Can a blocked person see my Viber messages?

They can see messages sent before the block. Nothing new reaches them from you while they are blocked, and nothing from them reaches you.

Do I get blocked messages after unblocking on Viber?

No. Messages sent during the block are not delivered later.

Does Viber tell someone they are blocked?

No, Viber does not send a notification.

Can I block a number that is not in my contacts?

Yes, from the block list in privacy settings or from the chat with that number.
