Those that use the Facebook application for iOS are probably familiar with the Messages tab in the application. From here, you can easily send messages to people that you keep in touch with through Facebook.

You may have noticed Facebook's constant push to get you to download their standalone Messenger application. This has always been the option of the user, and if they didn't want to download Facebook Messenger and would rather message from the main Facebook application, they could; but soon, Facebook users may not even have a choice.
