Many users can open the client application on their computer and connect to the server. Because all data is stored on the server, users can connect from any computer on the network and see and modify their data. Every user has access only to their messages and contacts, wherever they connect from. All changes are visible immediately, there is no need to refresh the view in the client application.

The following video demonstrates how changes instantly appear in two instances of SMS/MMS Manager, with each logged on user having different access rights. (running time 59 seconds)
