Currently, cellular communication is the most widespread of all types of mobile communication, which is why a mobile phone is usually called a mobile phone, although mobile phones, in addition to cell phones, are also satellite phones, radiotelephones, DECT phones, some models of IP phones and trunk communication devices.

9. Great harm to human health is caused by radiation emitted by the phone. No wonder we are constantly told that they do not carry the phone in their trouser pockets and do not put it near their heads. In no case should you keep the phone near infants and young children. For them, this radiation is especially dangerous. It damages some organs: visual, auditory, brain cells, visual retinas.
