There are many excellent triband cell phones. However, depending on your service carrier, a triban phone will not work in all places. Most Triband phones do not have the 850 MHZ frequency, which AT&T uses in many areas in the USA.Therefore, a quadband phone would be a better choice if you want to make sure your phone will work everywhere in the world.
