Official UK copy of the Bonn GSM mobile phone agreement, 1987

Official UK copy of the Bonn political declaration between the Ministers of France, Germany, Italy and the UK to support the GSM mobile phone specification in their respective countries and calling for the drawing up of the GSM MoU, signed by Geoffrey Pattie (UK), R Panella (Italy), Marcel Roulet (France) and Christian Schwarz-Schilling (Germany), in Bonn, 1987.

GSM stands for Global System for Mobile Communications (originally Groups Spécial Mobile), which was a European standard for 2G mobile networks, meaning that subscribers could use their phones across the whole of Europe. A key feature of GSM was the Subscriber Identity Module, commonly known today as a SIM card. This document was an early written agreement between the UK, Germany, France and Italy. It set out the terms of this agreement, stating that Europe should have a single standard for mobile communications, and that mobile network providers in all four countries must cooperate in order to provide commercial services that met this standard by 1991.
