Recently, the PTS (the Swedish Post and Telecom Agency) published statistical figures representing significant crossings of curves describing the use of mobile ICT in Sweden. The number of text messages (SMS) now exceeds the number of phone call minutes. And people in Sweden now spend more time talking on their mobiles than on their fixed phones.
A few years ago, we learned that the global urban population had reached a level where it exceeded that of the countryside. In spite of the lacking exactness of the statistics supporting this proclamation, it symbolizes an important development in the world. This point in time is set at the crossing of two curves: one representing the diminishing rural population and and the other the growing number of people living in cities. Even if certain hybrids are conceivable – commuting being the most important – city or country is by and large an either/or predicament.
The uses of mobile ICT:s on the contrary are more often related to complementarity than to substitution . The curves put forward by the PTS  represent the relative quantities of use of certain communication technologies and lack the strong historical significance of global urbanization. They point, however, at interesting trends concerning how communication media are adopted by people in daily life, in ways that increase their mobility.
According to PTS, “during 2009 more SMS were sent than call minutes were
made from private mobile subscriptions”. Texting has been growing rapidly, now to become the most frequent way of communicating via cell phones, and this in spite of the fast growth of mobile phone calls. Estimations by the PTS suggest that in Spring 2010, the use of the mobile (measured in minutes spent on the phone) exceeded the use of fixed phones. Also, the number of mobile broadband subscriptions is rapidly increasing, whereas the growth of fixed broadband has stagnated.
Text messages vs phone calls
It is fascinating that the popularity of texting is still growing in Sweden, a country where SMS messaging was adopted quite early. Among the advantages of texting are the possibilities to send or receive messages in situations where phone calls are inappropriate, as well as to delay answering until the time and place is right. The shorthand style of expression may also be seen as an advantage by those who want to avoid long conversations.
However, one cannot just compare the number of phone call minutes with the number of text messages. A telephone call is a dialogue with at least a question and a reply. It should be compared with an SMS conversation. If we estimate the number of such dialogues by dividing the figures for SMS by let’s say 2 (question + answer), texting still has a long way to go.
Mobiles vs fixed phones
The estimation that people in Sweden now use cell phones more often than fixed ones probably does not surprise anyone. It rather confirms a common impression that the mobiles are taking over and the fixed phones are on their way out. But there is more to be found here that what first meets the eye. Actually, the development of telephone use seems to be a case of substitution. According to the PTS graphs, the use of fixed phones is diminishing at the same rate as the use of cell phones is increasing, whereas the total time used for phone calls remains more or less the same. Thus, the mobile is taking over time hitherto spent on fixed telephones.
The hidden drama behind these seemingly trivial figures concerns the potential change of setting. The data themselves reveal nothing about where phone calls are made. In the case of fixed telephones, we can assume that most of them are carried out indoors, preferably at home or at work. Mobile phones, on the contrary, are used anywhere: at home, at work, but also in public space and on the go. So what we have is the quantitative manifestation of certain new conditions of everyday life, the very conditions of mobility that set people free from their dependence upon the base camps – or the fixed places – of their day.
The world of ubiquitous connectivity
There used to be a time and place for making phone calls. In Swedish homes, the telephone traditionally had its place in the hallway. Later on, extensions to e.g. the bedroom offered some individual privacy. When outside their homes or work places, people were inaccessible by phone. As we know, the mobile changed all that.
Much later, certain settings were forbidden or inappropriate for mobile calls. In the classroom, in church, in a hospital ward or during a concert, making a phone call meant breaking strong taboos. In others, for instance shops, waiting rooms, buses and trains, phone conversations could lead to irritation. Callers could be seen looking for the right niche for making calls without disturbing or being disturbed. Texting, to a certain degree, has changed that.
The ongoing development is of course in favour of mobility. In this world of ubiquitous connectivity, the airplane , absurdly enough, remains a haven, free from mobile interaction. And, of course, so does the far off wilderness, where the number of presumptive customers is to low to make the building of antennas lucrative. But only so far.
The fixed, stable and place-bound in communication is substituted by the fluid, changing and mobile. Today, information technology is less than ever a restraining factor for mediated interaction. However, in the world of fast and continuous accessibility, the heavy materiality and physical inertia of human daily life still exists.
