A mobile phone is a phone that can make and receive telephone calls over a radio link.
A mobile phone is a phone that can make and receive telephone calls over a radio link while moving around a wide geographic area. It does so by connecting to a cellular network provided by a mobile phone operator, allowing access to the public telephone network. By contrast, a cordless telephone is used only within the short range of a single, private base station.
In addition to telephony, modern mobile phones also support a wide variety of other services such as text messaging, MMS, email, Internet access, short-range wireless communications , business applications, gaming, and photography. Mobile phones that offer these and more general computing capabilities are referred to as smartphones.
