What Happens to Calls from a Blocked Number?

When a blocked number tries to call you, they won’t hear the usual ringing sound. Instead, one of the following might happen:

• Direct to Voicemail: The call is redirected to voicemail without notifying you.
• Disconnected Message: In some cases, the caller might hear a message saying the number is unavailable.
• Silence on Their End: The call might simply end abruptly without any explanation.

From your perspective, you won’t receive any notification or missed call alert. It’s as if the call never happened.

What Happens to Text Messages from a Blocked Number?

When someone you’ve blocked sends you a text message:

• The message doesn’t appear in your inbox.
• On some Android devices, blocked messages might go to a Spam or Blocked Messages folder.
• The sender won’t receive any delivery confirmation or failure notice, leaving them unaware that they’ve been blocked.

Can a Blocked Number Leave Voicemails?

Yes, in many cases, blocked numbers can still leave voicemails. These messages are usually stored in a Blocked Voicemail folder, separate from your regular voicemail inbox. This setup allows you to review the messages later if necessary.

Does the Blocked Person Know They’re Blocked?

Blocked callers aren’t directly notified that they’ve been blocked. However, they might suspect it if:

• Calls go straight to voicemail repeatedly.
• Their messages never receive a reply.
• They can’t see your Last Seen or online status in certain messaging apps.

For example, apps like WhatsApp and Facebook Messenger explicitly show blocking indicators, unlike the native Android call and text apps.
