I visited the SK Telecom1 ’s official blog (www.sktstory.com) and found this interesting video clip.
The following video clip shows some of the future services that SK Telecom is envisioning about. I think the service that uses the virtual reality on the screen is very interesting.

You can experience these demo services in reality at SKT’s T-um Airpot, Incheon Airport, Korea. If you have any chance to be at Incheon Airport, consider going there and try these services.
