Cellular telephones utilize very low frequency waves because they can travel long distances and penetrate obstacles such as buildings more effectively compared to higher frequency waves. This allows for broader coverage and better reception in rural or urban areas. Additionally, lower frequency waves require less power consumption, which helps prolong the battery life of mobile devices.
Cellular telephones use radio waves to transmit and receive signals. These radio waves are a type of electromagnetic wave that allows for wireless communication between devices.
High frequency waves will have more energy than low-frequency waves. This is because energy is directly proportional to frequency in waves - the higher the frequency, the higher the energy.
Radio communication typically uses electromagnetic waves in the radio frequency range, specifically in the Very High Frequency (VHF) and Ultra High Frequency (UHF) bands. These waves have wavelengths that are suitable for transmitting signals over long distances and are commonly used for broadcasting, two-way radio communication, and cellular communications.
This is known as the frequency of the wave.
The highest frequency electromagnetic waves are gamma rays, which have wavelengths shorter than 10 picometers. The lowest frequency electromagnetic waves are radio waves, which have wavelengths longer than 1 millimeter.

It uses radio waves. The frequency band is the same as some cordless telephones.
Your landline carries the voice/data on copper wires. A mobile uses radio waves but they are a different frequency from that used to broadcast TV.
Cellular phones operate using radio waves. With cellular transmission, a local area (ex. a city) is divided in multiple cells. The signals from the cell are transmitted to a receiver and integrated into the regular phone systems. Hence the name of cellular comes from these cells.

Garden spades and screw drivers are two devices that do not utilize radio waves.

The internet utilizes radio waves through wireless communication technologies like Wi-Fi and cellular networks. These technologies transmit data wirelessly using radio waves to connect devices to the internet without the need for physical cables.
