“Register your prepaid and get free calls/Internet transfer/win a car” – you can hear from Polish telecom operators, as a reminder and encouragement that all pre-paid SIM cards have to be registered by 1st of February 2017. One could almost think that this is just nicely coordinated campaign of leading telecoms, aimed at collecting a bit more data about their clients in exchange for a bonus. Nothing new under the sun in the data-driven world? Well, not exactly. A real stake in this data collection effort is to increase control over all users of telecommunication networks in Poland, with particular focus on foreigners. The demand for more data, this time, came not from the market but directly from the policing arm of the state.
