  In this study, Call Detail Records (CDRs), covering Budapest, for the month
of June in 2016 has been analyzed. During this observation period, the 2016
UEFA European Football Championship took place, which affected significantly
the habit of the residents, despite the fact that not a single match was played
in the city. We evaluated the fans' behavior in Budapest, during and after the
Hungarian matches, and found that the mobile phone network activity reflects
the football fans' behavior, demonstrating the potential of mobile phone
network data within a social sensing system. The Call Detail Records are
enriched with mobile phone properties to analyze the subscribers' devices.
Applying the device information (Type Allocation Code) from the activity
records, the Subscriber Identity Modules, that do not operate in cell phones
are omitted from mobility analyses, allowing to focus on people. The mobile
phone price is proposed and evaluated as a socioeconomic indicator, and
correlation between the phone price and the mobility customs have been found.
We also found that, beside the cell phone price, the subscriber age and the
subscription type also have an effect on the mobility. On the other hand, these
do not seem to affect the interest in football.
