You don't have to worry about the performance of your computer or your Internet connection. Wherever you are, wherever they are: Skype brings you closer. The majority of its features are totally free of charge, although you will have to pay for the most advanced options. It allows us to make video calls and conventional calls at low cost, apart from being able to exchange instant messages just like any other chat program. It appeared as a VoIP program to make video calls, but nowadays it's the successor of Messenger, also incorporating instant messaging functions. Skype is Microsoft's comprehensive communications platform.
