Argentina’s National Entity for Communications (Ente Nacional de Comunicaciones, ENACOM) has reduced the timeframe within which the country’s operators must complete the process of porting a mobile number from one provider to another, from five business days to just one. The new mobile number portability (MNP) rule was set out in Resolucion 170-E/2017, which was formulated on 30 January, but only included in the ‘Boletin Oficial’ on 10 March. The watchdog claims that a total of 4.7 million mobile numbers have been ported since the process was formally introduced in March 2012.
