Great , saves money, updated for iOS 10
Supports new iOS 10 voip integration called callkit. This makes call notification just like regular calls instead of having push notifications in previous versions, which is a huge improvement! Everything works very well except picture/video messaging. Sending pictures is awkward and receiving just doesnt work. Only complaint is the UI is a bit dated.
