WHAT IS IT?
A mobile phone or cell(ular) phone is an electronic telecommunications device. Most current mobile phones connect instead to the network using a wireless radio wave transmission technology (the exception is satellite phones). These mobile phones communicate via a cellular network of base stations (cell sites), which is in turn linked to the conventional telephone network. In the late 1970s and early 1980s the car phone was the only mobile phone available.
In addition to the standard voice function of a telephone, a mobile phone can support many additional services such as SMS for text messaging, packet switching for access to the Internet, and MMS for sending and receiving photos and video.*
