iPhone block caller what do they hear?

I am sure you must be curious on what happens on the other end?

When you block some number and he/she tries to send Message, then it will never show Delivered notification to them. But there will be no explicit message to them that the call or message was blocked.

However remember that the blocked number can still leave a voicemail – without being notified about it.

So when the blocked user calls you he will not listen to the ringtone but directly diverted to the Voicemail, without being notified to you as a missed call or a voicemail.

How to call even when someone blocked your number on iPhone?

Now I am looking from the other side of story, I mean some of your friend has blocked your number (maybe accidentally or you fought with him/her) and you still want him/her to call.

What to do?

There is a workaround if you also own iPhone.

Workaround 1 – Switch OFF Call ID

Go to Settings >> Tap on Phone >> Show My Caller ID >> Switch if OFF

Switching off call ID in the settings will make your number invisible to the receiver and any block on that number will be bypassed.

Workaround 2 – Use Google Voice mail

While you use Google voice mail which is FREE service, Google provides you different phone number and hides your original number, which is one of the easy and quick method to call someone who has blocked your number.

Read more on how to set Google Voice mail on iPhone in my detailed post here.

Workaround 3 – Dial from different number or use Country code

Generally the number is shown without country code, if your provider supports adding country code while dialing, in that case you can try changing that setting OR alternatively dial from different phone/landline number to really check if the other user have Blocked your number or it is Switched OFF.

WARNING! Please note that if someone has blocked your number and you are trying to call him using any methods described above, it may be considered as harassment or stalking, so its quite possible to have legal implications, so DO NOT DO THIS UNLESS EMERGENCY.

When I am tired, and want complete peace of mind …. I don’t want to talk to anyone at all … no calls …

One easy way is to switch OFF the phone!

But what if I want to watch a movie or listen to a song?

In that case best way is to use the built in feature of iOS which is using the DND feature. Let’s learn on how to do it.
