Yea me and the other 89,999,999 million ppl b/c they are the only one with service and/or b/c they bought and cornered the market... So what's your point? That it's my fault, just like it's my fault that Comcast monopolizes the TV industry or that Monsanto made the majority of the food you ate yesterday...
Yes, you and the other 90 million people bought into a technology that is not used by 99% of the world market. My point is that wherever I am in my travels my phone works flawlessly. I walk to a kiosk, purchase a $20 scratch card with a sim, slap it in my phone, and carry on. When I land back in the U.S. I revert back to my U.S. sim and don't ever have a worry.
Are you in an area that only has one carrier available? Unless you live in the boonies there is absolutely no reason to subscribe to any of the major carriers. A $45 per month Straight Talk, Cricket, U.S. Cellular, etc account would allow you to move around with your current phone as much as you want.
