Cell Phones Information: GSM vs CDMA and Frequency concerns.

This supplier tries to provide the best quality of support, and with the large variety of cellular phones offered, there are some factors you should be aware of. A large part of their cellular inventory consists of GSM phones.

Some GSM (Global System for Mobile Communications) providers include Cingular, Tmobile, AT&T, etc... A GSM network differs from a CDMA (Code Division Multiple Access) network in several ways, the easiest to distinguish by being that a GSM phone requires a SIM card (which is not included). SIM cards can be obtained from your provider.

When purchasing a GSM phone you should take into consideration which bandwidth frequency is available in your area. Please contact your service provider for assistance.

The frequency coverage depends on the area and your service provider.

GSM cellular phones only run on 4 possible frequencies, 850/900/1800/1900.

Quad Band phones can run on all 4 frequencies, Tri Band phones will only work on 3 out of the 4 frequencies, and Dual Band phones will only work on 2 out of the 4 frequencies.

850/1900 are US frequencies, and 900/1800 are international frequencies.

The majority of the Tri Band phones are 900/1800/1900 which means they work internationally as well as on a US 1900 frequency (850 frequency will not work).
