The amount of activities a cell phone can perform, normally sells itself. However, there is some technical mumbo jumbo that needs to be understood by the purchaser.
When you buy a cell phone and a plan or you choose a prepaid method you do not realize how exactly these small technological devises actually work.
The technology aspect holds more information when you want to know exactly how a wireless network operates. Look for GSM, CDMA, or TDMA, and read about how these connect your wireless service. It is quite interesting.
Cell phones have come along way, since they were first invented. TDMA ensures your call or text will be sent simultaneously. The cell phone operates sometimes better than communications that contain a wire.
The TDMA plays an important role in all 2G cell phones, and will continue until there is something better invented.
GSM provides technology for Cingular, AT &T, and T-mobile. While the other main provider, CDMA is responsible for Sprint and Verizon. These two sources are not consistent with each other.
For example, if you get a free phone as a promotion to sign a two-year contract with Sprint. Then you decide you no longer like what Sprint has to offer, and you sign a contract with T-mobile. You may have to purchase a phone that will work with the GSM versus the CDMA.
If you want a phone that will work with any network, the best choice is the Samsung.
Photographers usually are drawn to the SGH-e316 or the SGH-d900. Movie makers are more satisfied with the SGH-d406 or the SCH-d806. All four types are very enjoyable and will become useful.
