What happens when you block or unblock a number on Android?

When you block someone, the person can’t reach you via calls or messages. The blocked contact hears a pre-recorded message like “the number is busy,” “the person is unreachable,” or “the number is unavailable.” It varies from one carrier to another.

The recipient can always reach you via third-party apps like WhatsApp, Telegram, or Messenger.

When you unblock a number on Android, the person can contact you through regular calls and messages. The call history and messages that were blocked will not reappear.

Get rid of the spam without missing important calls

Sometimes, you may not have heard from someone because you accidentally blocked them. But not all blocked calls are spam. However, if you have a persistent caller, consult the National Do Not Call Registry or have your Google Assistant or Gemini mediate incoming calls for filtering.
