Most countries use one or two bands. Most Europe uses 900/1800 bands. Usually a Tri-band will work in most countries. They are either 900/1800/1900 or 850/1800/1900. There is no such thing as a quad-band country. I believe 850 is used only in USA and by Cingular. My 850/1800/1900 band phone worked in UK and Italy. So did my other 900/1800/1900 band phone.

Hi all
I'm trying to figure out whether i can use a tri-band phone in a country where they only provide quad-band service. Is it possible to use tri-band for quad-band service? What is the actual different between them?
