What Happens When You Block Someone on Android or iPhone

When you block a number on your iPhone, you won’t receive regular voice calls, FaceTime calls, or messages from them. However, you can still call or message the blocked person. In certain countries, the blocked person can still leave a voicemail, but you won’t receive a notification.

On Android, if a blocked person tries to call you, it will be declined automatically, and their messages won’t be delivered to you.

It is essential to remember that the blocked individual may still contact you via other applications, such as WhatsApp, Telegram, Facebook, and so on, as the block on these platforms is separate from the phone’s block. Find out what happens when you block someone on WhatsApp.

Frequently Asked Questions

1. How do I know if someone has blocked me?

There is no clear method to determine whether someone has blocked you. However, if your call is terminated or goes to voicemail every time you contact the individual, this might indicate that you have been banned.

2. Can I see if a blocked number has tried to contact me?

You will not receive notifications for any calls or messages from the blocked person on either Android or iPhone. In addition, their calls will not appear in the call log.

3. Do blocked messages get delivered when unblocked?

No. Messages sent during the blocked period will not be delivered after unblocking the person.

4. What do blocked callers hear?

Depending on your network, the banned callers will hear different things. In certain situations, they will only hear one ring before being terminated or routed to voicemail. Others are subjected to pre-recorded messages such as the phone “is not reachable.”

5. How do I block unknown callers on iPhone and Android?

On your Android phone, open the Phone app and go to its “Settings → Blocked number.” Enable the toggle next to “Unknown.”

On iPhone, you can silence the unknown callers by going to “Settings → Phone → Silence unknown callers.” These calls will be silenced and go straight to voicemail.

There are plenty of other things you can do on your phone to take control. Learn how to disable the emergency call feature in iOS and make private calls on your phone.
