I use GSM myself so I'm familiar with how easy it is to swap SIMs. But only two carriers in the U.S. are GSM. Sprint and Verizon are neither. Then consider that there are countries like Japan and Korea where 4G is already prevalent. So unless you can get every carrier on the planet to switch to compatible technologies that can use SIM cards, you're not convincing me. -Gary
