Nice one.
Good to see they are educating the market. First mover is always difficult.
I was recently in Seoul, South Korea for a couple of weeks. Used free wifi on my iPhone everywhere. DIDN'T NEED A SIM CARD. It was the same three years ago, these guys are light years ahead. I also note that Sydney Airport have free wifi (with login - collecting general demographic details and requesting permission to send offers).
This is the future.
