mobile phone (also called a
wireless phone or
cellular phone,
[1] but also
handy in
German and
kinito or
κινητό in
Greek) is a short-range,
electronic device used for mobile voice or data communication over a network of specialized base stations known as
cell sites. In addition to the standard voice function of a mobile phone,
telephone, current mobile phones may support many additional
services, and
accessories, such as
SMS for
text messaging,
email,
packet switching for access to the
Internet, gaming,
bluetooth, infrared, camera with video recorder and
