Detailed explanation-1: -It is a common misconception that making phone calls and sending text messages uses cellular data. These activities do not use data at all and most carriers now offer plans with unlimited talk and text.
Detailed explanation-2: -A microchip in the phone modulates (or varies) a radio wave using the electrical signal. The radio wave travels through the air to a nearby cell tower; the tower sends your voice to the person you are calling and the process is reversed so that the person on the other end can hear your voice.
Detailed explanation-3: -They move your digitized voice or data as oscillating electric and magnetic fields, called the electromagnetic field (EMF). The rate at which these waves oscillate is called their frequency. Radio waves move at the speed of light when carrying information. Cell phones transmit radio waves in every direction.
