Facebook Messenger began as a simple way to send messages to Facebook friends, but quickly evolved into a fully fledged texting replacement. Today, you can send pictures, your location, voice messages, and even make calls through the app — all without using any of your monthly minutes or texts. Facebook Messages sync instantly to the social network’s website, which means it’s easy to carry on conversations on your computer, then walk away and take your conversation to go. You might not trust Facebook, but by combining reliability with frequent updates and a presence on multiple platforms, Facebook Messenger might make you want to forget about your phone number.
