KM WhatsApp APK is a mobile application that allows you to send text and pictures for WhatsApp, Facebook and Messenger in one app. It does not have chat settings or some other extra features but it does do just that. You can simply use this app when you are out of WhatsApp, Facebook or Messenger apps and send messages without having to install any additional apps or worry about limit settings or other features of these apps. Just like your normal phone book app!
