Micro waves They travel through walls easily.
They are radio waves - in the microwave section of the electromagnetic spectrum.
radio waves
Cellular phone signals are carried by radio waves, which are like visible light waves only much slower and longer. Commonly used frequencies are between 800 and 900 megahertz, but some phones use frequencies as high as 2 gigahertz.
electromagnetic radiation in the microwave range some times cell phones use 50% uses and 50%health prombles overtimes don t uses
One of the technologies used in mobile phones is a fractal aerial design.
because the signals run through wires, not radio waves like cell phones do.
Mobile phones use microwaves - similar to those used in microwave ovens (but at much lower power !)
Simple Mobile has a variety of phones on their website that are compatible with their service. Phones that are compatible with T-Mobile can also be used with Simple Mobile.
