Messaging is a bit different than calling in the sense that you can’t send text messages to someone’s phone number through the Alexa app or your Echo—you can only send messages to other Alexa users. However, there are two ways to do this: using the Alexa app or using your Echo device.... One of the primary uses for Facebook is to send messages to friends. It’s a little more convenient than using e-mail, and you’ll often get quicker responses. Since Facebook patched the instant chat widget into the messaging system, the real time aspect has taken on a new light.
6/10/2010 · duh!Facebook is for you and ur friends to chat,if someone who isn't your friend and sends you a request,ignore it and block that person,then you wont have to worry about people who arn't your friends message you.
If you don’t want to receive messages from people who aren’t your friends, you could have your PS4 allow incoming messages only from friends. The “Friend Requests” option here is the same option as on the Connecting With Friends screen above.
