How does a cellphone transmit information using cellular network?

A cellphone transmits information through a cellular network by converting voice, text, or data into digital signals. These signals are sent to nearby cell towers via radio waves. The cell towers then route the information through a network of switches and servers to reach its destination, whether it’s another phone or the internet. This system allows for efficient communication over vast distances by dividing regions into smaller cells, each served by its own tower.
