Tri Band tech?
I'm just a bit confused as to what Tri band technology means. Does it mean that If you have a phone that is a Tri band/ Tri mode phone you can pretty much use it all over the world? You can use the same number? Please somebody, anybody explain this to me.
Thank you

A "band" is a set of frequencies. There are four in use in various places around the globe - 800/850, 900, 1800, and 1900 Mhz.
A "mode" is the type of signal coding your phone uses to communicate with the tower. The basic ones are AMPS/Analog, CDMA, GSM, IDEN, and TDMA.
For a phone to be usable, it has to match the mode and band of a tower in range. A phone with more modes or using more bands obviously has a wider assortment ...

many of the latest Motorola phones are either tri or quad band. Given the Myth's explanation, these phones work in between 850/900 to 1800/1900 mhz. As an example, the ATT network uses 850 mhz, the t-mobile network uses 850/1800 mhz, and the network for carriers like Vodafone or O2 are for 1900 mhz.

Don't confuse tri-band and tri-mode - they are very different. There are explanations for both in the glossary here on this site:
Tri-band:

Tri-mode:

Basically, tri-mode usually means a CDMA or TDMA phones that support analog. These phones will only work in North America plus a few scattered countries like Australia.
Tri-band is usually a GSM world phone.
The two U.S. bands are 850 (AKA 800) and 1900. The European / Asian bands are 900 and 1800. Latin and South America use a mix. So a tri-band phone supports 3 of those 4 and will work in most countries.
There are different types of tri-band, though. If you have T-...

Yes. Many networks use both bands.

Checking the above site, I see that:
- In Canada:
- Fido operates in the 1900 band.
- Rogers operates in both the 850 (AKA 800) and 1900 bands.
- In India, they use both the 900 and 1800 bands, which are totally different and incompatible compared to Canada. There are too many carriers to list here, so check the site I mentioned and see which carriers and region applies to you, and what band(s) they use there.
