Me, technology numb?

Call me technology numb, but I haven’t heard of unlocked cell phones here in my country. To gratify my curiosity I browse the internet and I came across this website called USTronics.com. This company provides unlocked cell phones in different models such as Nokia, Samsung, Motorola, Sonny Ericson, and much more. You can also buy a pre paid sim card which you can use in more than 125 countries without roaming cost and free incoming calls in over 80 countries. Isn’t unbelievable?
