Join instantly, and for free, the people in your life. Messenger is like texting, but you do not have to pay for every message (it works with your data plan).
Not just for Facebook friends: send messages to people in your phone book and simply enter a phone number to add a new contact.
Photos and videos: record videos and take selfies or other photos right in the app, and send them in one motion.
Get notifications when people have seen your messages.
Transfer the messages or photos to people who did not participate in the conversation.
Look for people and groups to contact them quickly.
Select the location to indicate that you are nearby.
See who’s available on Messenger and who’s active on Facebook.
