What Is Mobile?

• 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.
