How to send a message in WhatsApp with a number substitution - briefly?

To send a message in WhatsApp using number substitution, you need to modify the phone number of the recipient by replacing specific digits with their corresponding letters based on the standard telephone keypad layout. For example, to contact someone whose number is 123-456-7890, you would type 'abc-def-ghi0'. This method ensures that your message reaches the intended recipient even if their phone number is not stored in your contacts list.

How to send a message in WhatsApp with a number substitution - in detail?

To send a message in WhatsApp with a number substitution, you'll need to follow these detailed steps:

1. Access WhatsApp: Open the WhatsApp application on your device. This can be done via your mobile phone, desktop computer, or web browser. Ensure that you are logged into your account.
2. Select a Contact or Group: Navigate to the chat of the contact or group where you want to send the message. If you don't have their contact saved, you can use the search bar at the top to find them by their phone number.
3. Compose Your Message: At the bottom of the chat window, there will be a text box where you can type your message. This is where you will input the text that you want to send.

4. Substitute Numbers: To substitute numbers in your message, you'll need to replace the specific digits with their corresponding substitutions. For example, if you are using a simple Caesar cipher where each number is shifted by one place (e.g., 0 becomes 1, 1 becomes 2, and so on), you would manually substitute these numbers in your message.

   • Example: If your original message is "Meet me at 9 PM," and using the substitution method where each number is increased by one, the substituted message would be "Meet me at 10 PM."
5. Review Your Message: Before sending, carefully review your message to ensure that all numbers have been accurately substituted according to the method you are using. This step helps avoid any mistakes or confusion in communication.
6. Send the Message: Once you are satisfied with your substituted message, simply press the send button (usually depicted by a paper airplane icon) to transmit your message.
7. Verify Reception: After sending the message, it's good practice to verify that the recipient has received and understood your message correctly. You can ask them to confirm receipt or respond with an acknowledgment.

By following these steps, you can effectively send a message in WhatsApp with number substitution, ensuring clear and secure communication.
