Dual vs. Tri vs. Quad band phones
|
|
|
| In the states most GSM phones are 850/1900 MHz with a few 850/1800/1900
MHz. I see quad band (850/900/1800/1900) advertised as world phones.
Where do they use 1800 Mhz?

| The 1900 & 850 are used in the United States. 900 & 1800 are used overseas
with the 900 being somewhat more prevalent. It is not hard to find a quad
band phone in almost any price range, if you are going to travel
internationally at all go for that it will give you the best overall
cvoverage.

It's the secondary frequency in many countries, for carriers that came
on the scene late, and couldn't get any 900 Mhz spectrum. I.e. in
Taiwan, I bought a prepaid SIM card for a carrier that was 1800
Mhz-only. It worked fine in Taipei, not sure if it would have been so
great in the more rural areas of Taiwan.
A quad band is the best choice, but for a U.S. user traveling to Europe
or Asia, the tri-mode to get is one that is 850/900/1900.
