Written by O'News Blog

President Muhammadu Buhari has approved the implementation of the NIN-SIM linkage Policy with effect from the 4th of April, 2022 to restrict telephone lines not registered with their NIN.

All Telcos have been directed to strictly enforce the Policy on all SIMs issued (existing and new) in Nigeria which implies the outgoing calls will subsequently be barred for telephone lines that have not complied with the Policy.
