How does this technology work?
The telephone network extends worldwide, so you can reach nearly anyone on the planet. When you compare that to the state of the world just 100 years ago, when it might have taken several weeks to get a one-way written message to someone, you realize just how amazing the telephone is!
The fall backs to phones

Mobile phones use transmitting radio waves through a series of base stations where radio frequency waves are electromagnetic fields that cannot break chemical bonds or cause ionization in the human body, says the World Health Organization (WHO).
