“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.
