Now mobile phones are at all. Naturally, because it allows us to be in touch with loved ones at any time. I remember when there were no mobile phones, it was difficult to catch someone's home, calling on the city. A call to another city, people went to the post office and ordered negotiations.
Now everything is different. Parents can call the child to walk on the street and make sure he's all right. You can be in touch with old grandparents and time to come to their aid, if you suddenly need. You can prevent the person with whom you go to a meeting, if delayed or can not come. Thanks to the mobile phone it is possible at any time to contact with the right person. And this is a very big plus mobile phone, which has become very popular and accessible to all.
I believe that mobile telephony - is unconditional achievement of technology, which is a person in all spheres of life. The fact that some people manage to use mobile phones not only benefit, but harm - it is their personal choice that depends on their level of culture and understanding, and this is a separate topic for reflection.
