I am interested in buying cell phone online. But I do not know the phone can be used compatible with our mobile service. I am from USA.

Which carrier are you looking to use the phone on?

tri-band cell phone works well in USA,
but quad-band cell phone works in the worldwide.
(850/900/1800/1900)
so you'd better buy the quad-band cell phone.
if you are free, i recommend you a website,then you can find a quad-band cell phone.
