What does Tri Band mean?
[Top] Tri band refers to the physical frequencies which your mobile phone can operate on. The three international frequencies ranges or bands reserved for GSM are 900MHz, 1800MHz and 1900MHz. Tri Band phones can use all three GSM frequency bands, 900MHz, 1800MHz and 1900MHz. If you mobile phone supports tri band, and if it is using a tri band network, it will automatically switch between 900MHz, 1800MHz or 1900MHz frequencies without you even knowing – even while you are in the middle of a call!! For the GSM carrier, having dual or tri band phones means that they can also simultaneously support more mobile phone conversations.

Tri Band phones can use all three GSM frequency bands 900MHz, 1800MHz and 1900MHz.In Australia, as at the time of publication, most GSM networks still use only the 900MHz frequency band. Soon, GSM carriers will be upgrading their networks to support the 1800MHz band also. However, the 1900MHz band is only used in some parts of the United States and is unlikely to be used anywhere else in the world.If you mobile phone supports tri band, and if it is using a tri band network, it will automatically switch between 900MHz, 1800MHz or 1900MHz frequencies without you even knowing – even while you are in the middle of a call!! Right now in Australia, to the majority of mobile phone users, having a tri band mobile phone really has little effect on service or quality.
