Why are mobile phones called cell phones?

Answer 1

They are called cell phones because they are connected through a cellular network consisting of switching points and base stations (cell sites) owned by a mobile network operator. Cells are hexagonal(most commonly used shape) regions of area, defined by the operator within which all phones(registered with that operator) connect directly to a single base station set up by that operator. So, based on cells, hence cell phones.
Mobile phones are called cell phones because not of the actual phone, but because of the cellular towers. The sites have a honeycomb pattern that resembles cells. Because the mobile phones receive their calls from the sites resembling cells, they were dubbed "cell phones"

Answer 2

because they are a mobile version of the original concept (land line telephone) which were a stationary object. But a cell phone is a "mobile" version of a landline so they called it a mobile telephone or a "mobile" for short :-)

Answer 3

They are called cell phones because of the hexagonal shape of the towers, they resemble cell structures. The phones themselves actually have nothing to do with it other than they receive signals from the towers.

Answer 4

They are known as Cellular Devices. Telephone long way of saying phone. Instead of calling it a Cellular Telephone, they call them cell phones.
