How to block someone on WhatsApp without them knowing iPhone

If you want to block someone on WhatsApp without them knowing on an iPhone, follow these steps:

1. Open WhatsApp on your iPhone.

2. Go to the "Chats" tab and find the chat with the person you want to block.

3. Swipe left on their name to reveal more options.

4. Tap on "More" and then select "Block".

5. Confirm that you want to block the person by tapping "Block" again.

After you block someone on WhatsApp, they will not be able to see your online status, send you messages, or call you. However, they may still be able to see your profile picture and status updates, depending on your privacy settings.

Note that when you block someone on WhatsApp, it is a one-way action, meaning the person you block will still be able to see your messages and status updates if they have a saved copy of them on their device. However, you will no longer receive any notifications from them, and they won't be able to contact you anymore.
