Tri band phones (also known as tri-band or triband) are mobile phones that support three frequency bands. Having more than one frequency in one device is useful to enable roaming between different countries that peg the allowed transmission frequency at different values or to allow a better coverage in the same country. GSM frequency bands used around the world: 850 MHz (In America), 900 MHz (In Africa, Europe, and many parts of Asia and Latin America), 1800 MHz (In Africa, Europe, and Asia and many parts of Latin America), 1900 MHz (In America). 2G Triband phones are cellphones that support the GSM 900/1800/1900 MHz bands commonly sold in Europe, Asia and Africa, (for example the LG KE820 is a triband mobile phone that is sold in Europe, but works in big cities of America but not so well in suburbs and rural areas).Or alternatively the 850/1800/1900 bands (commonly sold in the Americas). The Motorola V300 formerly carried by Rogers Wireless used a rare combination of 850/900/1900. A 2G Quad band (850/900/1800/1900) offers more coverage and is now quite common.
