Cell phones have vastly changed the way we communicate today. A cell phone can be all you need for communicating. From a cell phone you can make calls, text message, BBM message, email, send and receive directions, go on the Internet, buy things, do online banking, listen to music and much more. In that one device you can do everything. There is no longer a need for multiple devices and you can be on the move doing it all.

A cell phone's basic function is to make and receive calls from anywhere you have service. Even though they can do more, calling is their main function. This function enables a person to make or receive a call without having to worry about location. The other basic function is location tracking in case of emergency. By law cell phones are built in with GPS technology that makes them "911 capable." This allows, if the cell phone is powered on, for your location to be tracked.

There are two types of cell phones: regular and PDA. Regular cell phones can have similar functions as PDAs, but they are mainly for making and receiving calls. A PDA, personal data assistant, is made more to be a portable office. These devices allow you to have all the functions of your office on the go. With a PDA you can track appointments, go online, email, edit documents, and send business cards.

With cell phone popularity rising, there has also been a rise in cell phone related accidents. While able to use a cell phone in the car is convenient, it has to be safe. Talking and texting while driving is dangerous. If you need to talk while driving there are two options you can choose. You can pull over or buy a hands-free device to use, such as a headset.

Additionally, some concern has been raised about cell phone radiation and how it might affect the brain if held against the ear for long periods of time. For this reason it can be important to check SAR levels (specific absorption rate) for a cell phone as they vary (see Cnet link in References).
