can Motorola MC75 be used in Europe?

I have never heard of a Motorola MC75 but in Europe and Asia countries uses either 900mhz or 1800mhz frequencies, depending on your service provider. So as long as the phone has the two band frequencies and the phone is unlocked, I don't see a problem. The only thing that you would have to figure out and work on is the web and text settings but your service provider should be able to help you with that.
