This is called a microwave and falls between the visible waves at the red end of the spectrum, and radio waves.
There are voice changers specifically for cell phones: http://www.spyville.com/cell-phone-voice-changer.html
No. A cell phone uses cell towers to transmit calls. A regular phone plugs into the wall or an adaptor of some sort.
Cell phones transmit sound as data through radio waves, which travel at the speed of light (about 671 million MPH). The signal is picked up by the cell tower, converted to digital information, and then transmitted to the receiving phone where it is converted back to an analog signal, resulting in sound through the speaker.
Depends on what kind of cell phone it is
To set up voice mail on your new cell phone, dial *86 and press send on your cell phone. You will be connected to instructions which will then walk you through the set up process.
A cell phone does not directly transmit sound. Instead it uses a microphone to convert what you are saying into electronic form. It then communicates with the cell station and sends it the electronic signals which represent your voice. The receiving person's cell phone then reassembles the electronic code representing voice into sound, using a speaker.
They needed to have a way to transmit the calls. Their solution was cell phone towers which allow the phones to carry a signal and make calls.
Radio waves are used in cell phone wireless communication technology to transmit and receive signals between cell phones and cell towers. These waves carry voice and data information over long distances, allowing cell phones to connect to the cellular network and communicate with each other.
The way a duplex functions in a cell phone is by having a two - way communication in which both terminals can transmit simultaneously.

Some cell phone companies may not allow voices messages to be left when a number has been blocked, while other cell phone companies will allow a voice message.
