(A) Probability density function of the amount of recorded spatio-temporal points per user during a month.(B) Probability density function of the median inter-interaction time with the service. (C) The number of antennas per region is correlated with its population (R2 = .6426). These plots strongly emphasize the discrete character of our dataset and its similarities with datasets such as the one collected by smartphone apps.
