For all earlier operating systems, use the Microsoft Lync Mobile app. The Skype for Business mobile app is available for Android 4.0 or higher, iOS 8.0 or higher and Windows Phone 8.1 or higher. This means that you can continue to make and receive voice calls, send instant messages and emails, and even participate in video calls – as long as you have a wireless or mobile data connection.
But what about times when you’re out of the office, or your computer and phone are inaccessible due to power supply interruptions? You can install the Skype for Business mobile app to your mobile device (phone or tablet) then use the device as a portable version of your office phone.
Using Skype for Business, you can use your computer to interact with colleagues and contacts in various ways.
