We use our cell phones all day, every day, but did you ever wonder what is really going on when you make or receive a call? Of course there are towers that we see dotting the landscape and it’s obvious that they make this all possible, but exactly how? Here is a detailed look at how cell phone calls actually work.

These phones have many of the same basic capabilities of a computer and their operating systems vary depending on the brand of the phone and user preference.

EWG has compiled radiation data for new phones given top marks by CNET, PCMag.com, PC World and Consumer Reports. Technical experts at these publications rate phones for performance, usability, features and aesthetics, but not radiation output, EWG reports.
