Cell Phones Information: GSM vs CDMA and Frequency concerns.
A large part of our 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 our 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). Please check with your provider for details on the frequency in your area prior to placing your order.
All phones intended for use with carriers other than GSM networks are marked accordingly.
As the majority of phones we offer are international models, and are not assigned to one specific carrier, unless marked otherwise, the GSM phones can be used on any GSM network: Cingular, Tmobile, AT&T, etc However for best service from your cellular phone, the above frequency regulations must be observed.
*Cell phones which are marked as unlocked ( being international phones ) are not capable of working on the internet. They are not enabled to browse the internet and will not be able to access it.
All phones intended for use with CDMA and IDEN networks are specifically marked.
