Pros.
It is really very convenient, in most phones there is the Internet, which allows you to instantly find the information you need or exchange a message with a friend, not only at home, on your computer or laptop, but also in any other place convenient for you.
You can call anywhere in the world and talk with the person you need.
The mobile phone is convenient and compact.
A mobile phone in some way replaces us with many items. It has everything you need, it can be a book, reference book, map, notebook, alarm clock and much more.
But, despite all this, mobile devices have disadvantages.
The very first and most important thing - a mobile phone can lead to various diseases, ranging from allergies to cancer. The radiation that the phone transmits is a big threat to the person in fact. An incredible amount of germs accumulates on the phone.
The second is that the phone "eats us." Now it’s much harder to talk to a person on the street and ask elementarily what time it is. For us, this is some kind of barrier to society. We are closing. This is not very good.
Also, the device absorbs a huge amount of our time, especially in adolescents.
