Mobile phones originated as mechanical devices in the late 19th century but have increasingly relied on digital technology since the 21st century. Cell phones work by sending and receiving radio signals between a network of cells, with each cell serviced by radio equipment that facilitates calls and messaging. While mobile phones provide connectivity and access to information, they can also be addictive and cause issues like distraction for drivers.
