1. What Happens if you block someone on WhatsApp?

These are the Things to Consider if You Want to Block Someone on WhatsApp.

i) WhatsApp Chat and Calls will not work anymore:

ii) The old Chat Remains Same as it was:

If you block someone then the chat (if exist) will remain the same to both (you and the blocked person). But, you can delete that chat manually anytime. Note that, there is no effect on doing this.



iii) Last Seen and Online Status will not be Visible:

Once you block a person the online status and activity will be hidden from that person instantly. Still, there are settings available to hide your WhatsApp profile picture from everyone.

But, there is a Catch.

…If you have been blocked by your friend in WhatsApp by a mistake, you will see a blank image for that contact or your sent messages will display one tick[not delivered].

In such cases just reach the person and request him to unblock.
