How can you see WhatsApp messages without opening them?

To see WhatsApp messages without triggering the read receipt (i.e., the blue check marks), you can use a method commonly referred to as "Airplane Mode Trick." Here's how you can do it:

1. **Receive the Message**: Wait until the message arrives on your phone. You will see it in the notification panel.

2. **Turn on Airplane Mode**: Quickly swipe down from the top of your screen to access the notification panel (on Android) or the Control Center (on iPhone). Find the Airplane Mode icon and tap it to enable Airplane Mode. This will disconnect your phone from the internet.

3. **Open WhatsApp**: Open WhatsApp while your phone is still in Airplane Mode. Navigate to the chat where you received the message.

4. **Read the Message**: You can now read the message without triggering the read receipts (blue check marks) because WhatsApp is unable to connect to the internet to send the read status to the sender.

5. **Close WhatsApp**: After reading the message, completely close WhatsApp. On Android, you can swipe it away from the recent apps screen. On iPhone, double-tap the Home button and swipe up on WhatsApp.

6. **Turn off Airplane Mode**: Once you have closed WhatsApp, turn off Airplane Mode to reconnect your phone to the internet.

By following these steps, you can read WhatsApp messages without the sender knowing that you have seen them, thereby avoiding triggering the read receipts. Keep in mind that this method requires you to act quickly to ensure WhatsApp doesn't send the read receipt before you can disconnect from the internet.
