A cellphone is any portable telephone which uses cellular network technology to make and receive calls. The name comes from the cell-like structure of these networks. There are some confusions about cellphones being a different thing to smartphones, but technically, every mobile phone, from the latest Android handset to the simplest feature phone, is a cellphone. It is all about the technology used to transmit your calls, rather than what the handset itself can or cannot do. As long as a phone can transmit a signal to a cellular network, it is a cellphone.
