Nigerian phone users whose devices fail a new regulatory verification process face disconnection from national networks after 30 days, the Nigerian Communications Commission (NCC) has warned. The regulator is advising owners to check their handset's status now via a simple USSD code, before the deadline tightens around unapproved hardware.

The measure plugs into two systems the commission launched in 2024: the Device Management System (DMS) and the Central Equipment Identity Register (CEIR). Both platforms are built to identify mobile devices crossing onto Nigerian networks and to block handsets that never received type approval. Text messages warning of potential disconnection have reportedly gone out to owners of devices from multiple brands, and anyone who receives one can dial the verification code to check whether their phone passes muster.

The stakes for consumers are concrete. A phone that fails verification stops working as a phone, regardless of whether it was purchased in good faith. Consumers in that position are advised to contact the seller or the NCC directly.

How does the system actually work?

The technical backbone is the International Mobile Equipment Identity (IMEI) number, the unique identifier assigned to every mobile handset. By tracking IMEIs against its central register, the NCC can flag cloned, stolen or unapproved devices as they attempt to connect — roughly the same principle behind SIM registration, only applied to the hardware rather than the line.

The commission lists several aims for the programme:

• Targeting counterfeit phones circulating in the market
• Combating phone theft
• Preventing cloned or stolen devices from being used in criminal activity
• Improving overall service quality on Nigerian networks
• Strengthening compliance among importers, manufacturers and dealers

What is the legal basis?

Type approval for mobile phones in Nigeria is a mandatory certification process managed by the NCC under Section 132(2) of the Nigerian Communications Act 2003. Certification is meant to ensure devices work properly on local networks without causing dropped calls, degraded service or signal interference. It also serves a consumer-protection function, screening out counterfeit or substandard handsets that may carry health and safety risks such as high electromagnetic radiation.

The regulatory context matters here. This is not the NCC's first attempt to record who owns what in Nigerian telecommunications. Earlier this decade the commission rolled out mandatory SIM-card registration, a process that by some estimates took at least four years to complete. The device-level push now underway extends that same logic from the subscriber to the handset itself.

Why imported phones are the flashpoint

The commission's biggest headache is the gray import market. Some devices entering Nigeria have simply never gone through the required type-approval process, and for years many Nigerians have relied on phones brought in from other countries to obtain models that are unavailable locally or cost more through official channels. Those handsets are now squarely in the verification net.

The NCC acknowledges the problem and says a registration pathway is being designed for legitimate owners of imported devices. Details of that process are expected to be published soon — a timeline that will determine whether millions of otherwise lawful handset owners face an abrupt cut-off or a managed transition.

What happens next

For now, the practical advice from the regulator is straightforward: dial the USSD code, check the device status and act within the 30-day window if verification fails. With the imported-device registration pathway still unpublished and warnings already landing on handsets across multiple brands, the coming weeks will show whether Nigeria's device register matures as slowly as its SIM registration drive — or moves faster this time.
