Mobile Phone, called MP for short, is an electronic telecommunication device which also often referred to as a cellular phone or cellphone. Except that it can fulfils the need of remote voice communication between individuals no matter where they are, most mobile phones provide Short Message Service (SMS), Multimedia Message Service (MMS), and modern phones may also offer Internet services, like Web browsing and e-mail.

In 1983, Motorola introduced the first truly portable cellular phone to the world which used analog technology. It was called the Motorola DynaTAC 8000X. It was approved for use in the United States by the FCC. The DynaTAC800X was extremely lightweight for its time and only weighed about 28 ounces. It was 13 inches x1.75 inches x3.5 inches and was known as a large briefcase and very inconvenient.

During the 1990s, great improvements were made in the mobile phone technology, GSM, IS-136 (TDMA) and IS-95 (CDMA) mobile phone systems appeared. Digital mobile phone networks were in use in the United States in 1990 and in Europe by 1991. The new technology also made them capable of being smaller rather than the large briefcase-sized units from the 1980s.

The latest generation of mobile phone is the technology referred to as 3G which is currently used today. This new technology is not only capable of transferring voice data (such as a phone call), but it is also able to transfer other types of data, including emails, information and instant messages.

Nowadays, Mobile phones come in many shapes and sizes with varying amounts of special features, including cameras, video recorders, music players and radio, web browsers, 3G and Bluetooth.
