My favourite stat is: "A third of South Korean students send over 100 SMS messages a day" That'll give you an idea of how much more Asian countries use SMS than European ones. Also Japan tends to be a special case as they use different protocols. There mobile email is popular whilst SMS is non existant. As for startup potential, look at twitter for a start. They added the ability to make one-to-one private text messages into a one-to-many public broadcast network. Theres plenty of other possible permutations left to try.
