I am going to show you how WhatsApp works. This is really easy to use and it helps you to contact your friends. This uses mobile data unless you have wifi. Its a easier way to message people and you can even send pictures, voice messages and even emojis. You can even call and face time people off of it. This will even send to people if they are on the other side off the world. You can also make group chts and things like that so you can speak to more than 1 person at a time. Also after a year you need to pay £0.99p.
