Smartphone Messaging Apps

Having a computer in your pocket is the norm nowadays with the proliferation of smartphones. That means that communicating over the Internet with specialized apps has become the norm as well. After all, why potentially subject yourself to international calling fees and poor cell reception when you can just call someone using WhatsApp or Telegram or Signal and not pay any money at all for substantially better audio quality?

Those three apps and more can be found on this page and provide free and easy-to-use interfaces to send text-based messages; attach photos, videos, and music; and make free voice (and oftentimes even video!) calls internationally.
