Skype was one of the very first pieces of software that allowed video calling in addition to phone calls. You can use it for free via WiFi, or sign up for a calling plan where you can contact other mobile numbers. Most users are familiar with video calling and messaging apps, but Skype runs on a powerful server that helps maintain a stable connection. It’s very easy to use and has an intuitive interface. Skype is a free calling app that enables video and voice chat as well as instant messaging.
