In today's world there is absolutely no need to explain what mobile communication is and what role it plays, with every day, there are more and more mobile subscribers. Moreover, the audience is becoming younger and younger. If at the very beginning of the era of mobile communications the majority of people using mobile phones where adults, especially businessmen and people working with clients, today there is a great percent of children having mobile phones. Of course, for parents it is much more comfortable to buy a mobile phone for their child and have an opportunity to stay in touch with their son or daughter than to worry constantly where he or she is. The audience is younger, and our requirements and standards are higher. There are not so many people around us who will be satisfied just having an opportunity to call somebody or to receive a call. More and more often we turn to mobile internet access and are extremely disappointed if its speed is not high enough.
