Mobile phones are now ubiquitous in villages as well as cities. If an individual does not have a cell phone, they almost surely know someone who does a reverse phone number check. Mobile phones are low power radio devices that transmit and receive radio frequency radiation (at frequencies in the microwave range of 900-1800 MHz) through an antenna used close to the user’s head. Digital systems have recently replaced analogue. Mobile phones are so integral to our lives that it’s difficult to remember how the heck we ever got on without them. Mobile phones are becoming popular for many reasons.
