Nowadays every person has a mobile phone. The usage of the mobile phone allows us to be in touch with our relatives at any time. Thanks to mobile phone there is a possibility to contact the right person at any time. To my mind, it is a very big plus for mobile communications, which has become very popular and accessible to all.
However, there is the reverse side of the medal. Firstly, sometimes people call each other at an inconvenient moment, they may distract from the important things. Secondly, mobile communications limit a face-to-face contact. People prefer to talk on the phone than to meet somebody in real life. People are paying less attention to the persons around them. People become attached to their phones.
I believe that mobile communications are a key achievement of technique, which is used in all spheres of life, but we should not forget the joy of real-world communication.
