Following several postponements of the deadline for people to link their NIN to their SIM, the Nigerian Communications Commission (NCC) has now mandated all telecommunications operators in the country to block all outgoing calls on SIM cards that are not registered with the National Identity Numbers (NIN), which took effect on April 4th, 2022. As a result, many Nigerians who have not enrolled for NIN or who have been unsuccessful in linking their phone number have had their line restricted from making outbound calls.
