How to send message without saving number on WhatsApp.

• WhatsApp Messenger allows people to send fast messages, videos, pictures, and brief audio messages to either one person or within a group conversation. Messages will only be sent to other cellphone users who also use WhatsApp. Once you install this app, it uses your contacts to see if anyone else you remember is already using WhatsApp and connects you automatically.
• However, there are situations when you need to send a message to someone who is not in your contact list. It might be a single message that is sent.

• If you are using this on a mobile phone, it will launch WhatsApp automatically; however, if you are using a web browser on a desktop, it will ask you how to open WhatsApp.
