The Japan and Korea implemented 3G 2100 MHz networks before anywhere else in the world. They are among the only countries in the world that don't have a GSM network in the 800/900/1800/1900 MHz bands. GSM is the only technology that can truly be called a global technology.
Take a look at the coverage map on www dot gsmworld dot com slash roaming slash GSM_WorldPoster2006A.pdf. The poster depicts 3G 2100 MHz as well so it's a bit misleading, but the point is made - GSM covers almost the entire world population. (Sorry, I can't post an URL.)
