There should be a working phone where you can PM people but only your friends and check the Cubic Time and listen to tunes and you have to buy the tunes for your phone. Also, you should be able to call people like request them to respond, or teleport. There is even more things that could be added to this, so it has a lot of potential...

But maybe if they aren't online in Cubic Castles and you want to tell them something, it will give them a notification that you messaged them while they weren't online.
Also meybe better thing would be sms. Mods already have their own chat why shouln't players could talk to each other while they are in separate realms?
