Polish mobile operators had less than 52m SIM cards in Q1 2017, according to the Central Statistical Office of Poland (GUS). It was about 4.6m SIM cards less than in Q1 2016 and ca. 5.2m less than at the end of Q2 2016. This drop is mainly associated with the anti-terrorism law introduced last year. As a result, the sales of new pre-paid SIM cards decreased, while at the same time the number of post-paid SIM cards rose. The total number of deactivated pre-paid SIM cards reached ca. 7 - 8m. The highest amount of active SIM cards in Poland (59m) was recorded at the end of Q3 2015.
