Skype is for doing things together, whenever you’re apart. Skype’s text, voice and video make it simple to share experiences with the people that matter to you, wherever they are. A great tool to connect on any device, and if the person you are connecting with doesn’t have skype, you can purchase a “Skype out” number and call telephones from your computer.
If your guest doesn’t have a microphone, a great alternative is to have them install skype on their smartphone and use it over wi-fi.
