Cell phone

A cell phone (also called variously mobile phone wireless phone, cellular telephone, cellphone, cell and hand phone) is a long-range, portable electronic device used for mobile communication that uses a network of specialized base stations known as cell sites. In addition to the standard voice function of a telephone, current cell phones can support many additional services, and accessories, such as SMS for text messaging, e-mail, packet switching for access to the Internet, and MMS for sending and receiving photos and video. Most current cell phones connect to a cellular network of base stations (cell sites), which is in turn interconnected to the public switched telephone network (PSTN) (the exception is satellite phones).
