"Cell phone" redirects here. For the movie, see Cell Phone (film).
The mobile phone or mobile, also called a wireless, cellular phone, cell phone, cell speaker box, or hand phone (HP),[1] 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 mobile phones may support many additional services, and accessories, such as SMS for text messaging, email, packet switching for access to the Internet, and MMS for sending and receiving photos and video. Most current mobile 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).
