The GSM standard had an additional export advantage compared to the US and Japanese standards. The joint development of a pan-European standard led to the inclusion of a multitude of features which different countries required due to their preferences. The GSM standard became therefore a multi-environment standard. For instance, Germany required the inclusion of the SIM card for security reasons, Britain and the Nordic countries required technical features that made small handsets possible. Britain wanted data communication abilities. These different national requirements mirrored their own good experiences with their first cellular generations. Although this led to nerve-breaking discussions in the standardisation committees, GSM became an amalgamation of the best features of what different environments made transparent. 

Standard PVC card films (homopolymer) have a VST of 349 K. To achieve high VST values, special blends of PVC/ABS card films (0.25-0.8 mm thick) are engaged. High-VST (364 2 K) cards are required in environments with high temperatures and stress. Applications include SIM (GSM) cards and pay TV cards.
