Most cell phones that get good reception in foreign countries use a fourth band of frequencies called QUAD-BAND. Most cell phones that use quad band usually cost from anywhere from 20 to alot of dollars with a service plan. Alot of cell phone companies can also sell you a long distance calling plan. Where you get unlimited calls to selected countries for a set price each month. This is the CHEAPEST way to use a cell phone in other countries without using a landline or a satelite phone
