Argentinian telecoms regulator the National Entity for Communications (Ente Nacional de Comunicaciones, ENACOM) has informed pre-paid mobile phone users that they have until Thursday 18 October to register their SIM cards, or face disconnection. The process was initiated back in November 2016, when the Ministry of Communications (Ministerio de Comunicaciones) and the Ministry of Security (Ministerio de Seguridad) agreed Joint Resolution 6-E/2016, which was published in the Official Gazette that month. Since May 2017 all pre-paid users have been obliged to provide ID and register their details when buying a new SIM card.
