What is a GSM world phone?
A. GSM world phones are devices that operate on international frequencies. These can include “tri-band” phones/devices (which operate on three of the four GSM frequencies) and “quad-band” phones/devices (which operate on all four of the GSM frequencies). GSM networks in North and South America operate at frequencies of 850 or 1900 MHz, while most networks in other countries operate at frequencies of 900 or 1800 MHz. AT&T also offers phones that operate on 3G technology at 2100 MHz to roam in Japan and South Korea. AT&T recommends quad band phones/devices for most international travelers. Since these wireless devices operate on all four of the international GSM frequencies, you ensure the broadest international coverage available.
