What Is The Cell Phone GSM Feature?
Cell Phone GSM is a system of identification used by certain cell phones that determine just how they communicate with their cell phone network through cell phone towers.
The Term “Cellular Phone GSM” refers to a cellular phones "Global System for Mobile communication” and is the most widely used form of cellular phone communication in the world. Ironically, one of the biggest cellular phone markets, the North American market, doesn’t hold the same view on cellular phone GSM’s as the rest of the world. Of course, people in North America have always had their own way of doing things.
Cellular phone GSM is one of three major cell phone communication systems in the world, the other two being CDMA and TDMA. CDMA stands for Code Division Multiple Access while TDMA stands for Time Division Multiple Access. Global system for mobile phones is closely related to TDMA, although the two are essentially incompatible. The two share a common platform but use it differently.
Think of it as Canadian Football and American Football. Although they both contain end zones, footballs and touchdowns, they are two very different games.
In North America, GSM was once a distant third to CDMA and TDMA. A lot of that has changed now though, since companies such as AT&T wireless and Cingular have switched over to GSM networks and left TDMA struggling far behind.
One thing that sets cellular phones GSM’s apart from their peers is the exclusive use of SIM cards. If you have ever had a cell phone made for a company that uses global systems for mobile phone communcation then you know exactly what a SIM card is.
A SIM card is a small card that fits in a special slot in your cell phone, often in the back or bottom of the handset itself. About the size of a dime, SIM cards allow you to switch your account from one phone to another simply by removing the SIM and placing it in another phone. That way, you can transfer all your important information – including phone numbers and addresses quickly and painlessly from one phone to another.
On the downside, SIM cards are a cause of concern for anti-theft security because once a cellular phones GSM is stolen, a new SIM card can easily be popped into the handset and the thief now has a brand new phone.
Thankfully, companies such as Nokia and Mitsubishi as well as providers such as Cingular and AT&T are busy fighting cell phone scammers and thieves at every turn.
