Telecommunications operators have resumed SIM swap services after recent disruptions that impacted millions of subscribers across Nigeria.

MTN and Airtel confirmed the development on Sunday, explaining that the earlier delays were caused by challenges accessing the National Identity Management Commission’s verification platform.

In a post on its MTN Nigeria Support account on X, MTN stated, SIM swaps have now resumed. We can confirm that NIMC services are fully operational and appreciate their support in the migration to a new platform for NIN verification services for the telecommunications industry.”

The telco also acknowledged the earlier disruption and advised affected customers to visit its service centres for assistance.

Airtel Nigeria also issued a clarification on its social media platforms, stating, “The NIMC PORTAL is up and running. We regret earlier messages suggesting otherwise. We are sorry for the delay and are addressing the issue. We’ll update customers once resolved. We value our partnership with the NIMC and value your patience.”

The National Identity Management Commission via its official X account, amplified both MTN and Airtel’s updates, confirming that SIM swap services have resumed across multiple networks.

Both MTN and Airtel have urged customers still facing delays to visit the nearest service centres for prompt assistance, while expressing appreciation for their patience during the disruption.

Earlier in July, millions of telecom subscribers across Nigeria were unable to access SIM-related services—including swaps, replacements, and new activations—due to a nationwide technical outage.

The disruption was linked to a platform migration initiated by the NIMC, which temporarily impacted access to the NIN verification system used by telecom operators.
