Tri-Band

Tri-band is a digital cellular technology. Tri-band capability gives you the ability to make and receive mobile phone calls from around the world.

A number of GSM phones, such as the Nokia 6310i shown to the right, are compatible with all 3 GSM frequencies:

GSM 900 and 1800 bands (prevalent in Europe, Africa and Asia) and North-America's GSM 1900 band.

Yet others, such as the Nokia 6650, can make use of WCDMA networks as well as GSM networks.
