It must be noted that every cell phone has several features in common. The only difference arises because the manufacturers constantly want to outshine the other, therefore adding or subtracting other features in the process. This has led to numerous innovations that have popped up in more than 20 years. This is the main reason why we see so many brands and models of mobile phones on the market today.

Although cell phones look very different from one another, they have features that are similar and cannot be changed. These features include the battery. Most of the mobile phones have one power source, which is the battery, and this keeps the phone ?alive? and allows it to function. Phones with the GSM, WCDMA, iDEN and most of the satellite phone devises are uniquely identified by the IMEI number.

The basic principle of the mobile phone is to make and receive calls as well as send and receive text messages. All the GSM mobile phones use the SIM card, which allows an account to be swapped among other devices. But at the same time, the other mobile phones that use the CDMA devices have a similar card referred to as the R-UIM. The mobile phones also have an input mechanism that the user uses to interact with others. This is common among many phones where they use the keypad. However, the touch screens have been found in some smartphones.

Phones can further be categorized into two groups. There is a? feature phone, which only provides the basic phone functions, and the digital phone, which has some additional features like the GPS navigator. Some of the phones also have the electromechanical transducer which changes the electric voice into mechanical vibrations.

The commonly used data on the phones is the SMS text messaging. The first mobile text to a computer was sent in 1992 in the UK. Mobile phone to mobile phone text was sent in Finland in 1993.The non-SMS data services that are found in the mobile phone include the downloadable logos and pictures, games, adult entertainment and the mobile music. The first time some of these features were sent to the phone was in 1998, and it was done in Finland. Cell phones have come a long way since they were first created. And it looks like they have a long, busy future ahead.
