I would like to know the difference between TRI dual and quad band GSM?
Different regions of the world operate on different wireless frequencies. The multi-band phones support of at least three frequencies – a U.S. band and two international bands: 900 MHz, 1800 MHz and 1900 MHz are not misled by the tri-band phones operating in both U.S. frequencies, but only one of the international frequencies – that is not so useful. On the other hand, if you have the option of a telephone quad band cell, one that supports 850, 900, 1800, and 1900 MHz, will have all the bases covered.
