It seems that calling and telephones will never become obsolete. Phones have been available to people for at least one hundred years. Nothing indicates that the situation is about to change anytime soon. On the contrary, it seems that everybody has at least one mobile phone or more to make his conference calls when he needs to do so. Mobile phones are becoming more and more complex and useful. The newest models have features that older mobile phones simply do not have. You can do almost everything with your mobile phone, including connecting to the Internet or taking pictures of those who are around you.
