NIN-SIM Linkage, Status and Failed Verification Guide
Link NIN to a Nigerian SIM, check linkage status, fix failed verification and escalate unresolved telecom complaints.
A SIM can remain restricted even after a customer submits a NIN if the record has not verified successfully. This hub separates first-time linkage from status checks and failed-linkage troubleshooting.
If the network does not resolve the issue after the required first complaint, use the NCC complaint guide for the escalation route and evidence to keep.
