The Regulation Authority for Telecoms and Post (ARTP) has issued formal warnings to Senegal’s three major mobile network operators (MNOs) – Orange, Free and Expresso – for failing to meet quality of service (QoS) standards. The regulator noted it had been compelled to take action after a recent audit revealed ‘failings which negatively impact the electronic communications sector and cause enormous disruption to consumers’. Under Article 177 of the Code of Electronic Communications, the three companies have been given 30 days to meet agreed QoS obligations for mobile voice and data services or face sanctions.
