Cell phone companies.

Nokia Corporation produces many new and technologically advanced Nokia cell phones. Some examples are Nokia 9290 Communicator which provides access to many business related features, Nokia 3589i Phone which has many advanced features and Nokia 7210 Phone which allows you to exchange pictures. Samsung has many excellent phones such as the SPH-a600 digital camera cell phone that enables access to the web and the SGH-e105 phone that enables multiple messaging capabilities. Another example would be Motorola cell phones like the Motorola T720i camera phone.

Wireless standards for cell phones.

Currently, in the US, cell phones use analog service or digital service. Most new cell phones use digital technology. Three digital wireless technologies are currently used in the US: TDMA (Time Division Multiple Access), CDMA (Code Division Multiple Access), and GSM (Global System for Mobile Communications). Unfortunately, many times digital cell phones can work with only one technology: TDMA, CDMA, or GSM.

Choosing a cell phone.

First you need to find the cell phone plan you want to subscribe to. Once you’ve decided on your service plan and cell phone company, and you’re happy with the cell phone services that company offers, you can select the phone you want. By first selecting a carrier and service plan, you protect yourself from the mistake of selecting a cell phone that uses a different technology than what your wireless provider offers. At this point, you can choose the phone that has all the functions and features that you want.
