Skype released an official version of the Skype for Windows Phone app, which is now available in the Windows Phone Marketplace. You can also get the app directly from your Windows Phone.
With Skype on your Windows Phone, you can join the thriving community of 200 million people using Skype every month across almost any screen: smartphones & tablets (running Android, iOS, and Symbian), computers & laptops (Mac, Windows) and connected TVs. See the video above to see how the app works.
Available for use on 4G, 3G and WiFi networks, Skype for Windows Phone helps you connect with friends and family instantly with free voice and video calls everywhere you go. Make affordable calls to landlines and mobiles using Skype Credit, create and hold one-to-one and group chats (even while in the middle of a call), and update your profile and account information, among others features.
