Microsoft last week announced at the Mobile World Congress that Facebook Messenger was coming to Windows Phone, and today it's available
from the Windows Phone Store.
With Facebook Messenger, you will be able to see who's online for a private or group chat, send a private message, and bring messages to life with pictures and stickers. You can also share your location so people can know if you are nearby. All your Facebook friends are automatically adder to the People Tab for you to get started sending messages but you can also import new contacts too.
