With this, you don't have to save your contact number in order to send a message or make a call to a friend or family member. This is because the app has been designed to work with WhatsApp, an instant messaging app that is popular around the world.

With it, you can send and receive messages directly on your phone number, no matter if it's the one you have registered with your phone provider or not.

This is an extremely useful tool for people who want to keep their phone numbers anonymous, but at the same time don't want to lose the ability to send messages to their friends and family members.

The best part is that you don't have to download anything in order to send a message or make a call.
