GSM Triband

Hi

Can someone tell me what GSM Triband means?

Thanks

Woby_Tide

it means it can work on the main 3 frequencies mobile phone networks use, the majority of Europe and Asia use only 2 networks so lots of phones are dualband, North and South America use a 3rd frequency generally so triband phones will work over there too

Four major frequencies in the world for GSM:

900, 1800, 1900 and 850.

The first two are the most common in the majority of the world (apart from America, Japan and South Korea - Japan and South Korea use a seperate technology from the rest of the world though).

1900 is the mainstay for America.

Some countries are also starting to use 850.

Triband phones normally will have the 900, 1800 and 1900 frequency.
