The Nigerian Communications Commission (NCC) has introduced a device-checking system to strengthen enforcement of mobile phone approval requirements, as Nigerian users report receiving text messages warning that some phones could be disconnected from local networks after 30 cumulative days.
The messages, reportedly sent under the sender name “NCC-Checker”, have raised concerns among owners of smartphones, including iPhones, Samsung, Tecno and Infinix devices. However, receiving a warning does not automatically mean a phone is fake or stolen, and users should verify their device status before considering a replacement.
The NCC’s official Device Checker allows users to check whether a device has the required type approval and is verified for use on Nigerian mobile networks. The commission provides access through the USSD code *315# and its official Device Checker website.
How to check your phone’s NCC verification status
Phone users can start by dialling *315# on their devices and following the instructions displayed on the screen. The service is intended to check the device currently being used, although users checking another phone may be asked to provide its IMEI.
The result should indicate whether the device is type-approved and verified for use on Nigerian mobile networks. If the result is unclear, the user should consult the official online checker or contact the NCC or their mobile network operator for assistance.
The NCC’s approved handsets register is another useful resource. It lists devices that have been tested and found to meet the applicable type-approval standards, including their equipment names, model numbers, manufacturers and certificate holders.
To search the register, users need their phone’s exact model number, rather than relying only on the brand name.
On most Android phones, the model details can be found under Settings and then About phone or About device. iPhone users can go to Settings, select General and tap About.
A model number that closely resembles the one listed by the NCC is not necessarily an exact match, so users should compare the details carefully.
Why the approved phones list may not be enough
The NCC distinguishes between type approval for a particular device model and verification of an individual handset.
Type approval confirms that a model meets the commission’s applicable technical requirements. Device verification, meanwhile, checks whether the particular handset is recognised for use on Nigerian mobile networks.
This distinction matters because a phone model appearing on the approved register does not, by itself, establish that every individual device of that model has completed the necessary verification. Equally, the absence of an immediate match does not prove that a phone is counterfeit.
Users can find their device’s International Mobile Equipment Identity (IMEI) by dialling *#06#. Some dual-SIM phones display two IMEI numbers.
The IMEI is a unique device identifier used in mobile network verification. Users should keep it private and enter it only when required through the NCC’s official verification process or another trusted channel.
Will phones already being used in Nigeria be disconnected?
The NCC’s published frequently asked questions, updated in October 2026, state that phones already connected to a Nigerian mobile network before the system took effect on October 7, 2026, were automatically verified and generally require no action from their owners.
The commission also says phones bought within Nigeria, including new and second-hand devices, and phones passed between family members or friends do not ordinarily require additional action under the rollout. However, it advises users whose devices cannot be verified or are affected by a compliance restriction to contact their seller or service provider.
This official guidance is important because reports of warning messages have caused confusion among people who have used their phones on Nigerian networks for years.
The NCC has said that a phone brought into Nigeria from abroad for personal use may be used with a Nigerian SIM for up to 30 cumulative days within a one-year period before verification is required. Different procedures apply to devices imported commercially for sale.
The commission’s stated objective is to improve compliance with existing type-approval requirements, identify non-compliant devices and help prevent stolen or illegally imported phones from operating on local networks.
What to do if your phone receives a warning
Anyone who receives a message claiming that their device will be disconnected should take the following steps:
- Check the device status. Dial *315# or use the NCC’s official Device Checker to follow the verification process.
- Confirm the exact model. Compare the model number with the NCC approved handsets register. Do not rely on the brand name alone.
- Keep evidence. Save the warning message, the verification result, your purchase receipt and relevant warranty or order details.
- Contact the seller or importer. If the device was recently purchased, ask the seller to clarify its approval and verification status. Businesses supplying devices in Nigeria have responsibilities under the applicable regulatory requirements.
- Contact the NCC or your network operator. If the warning persists or the result appears inconsistent with the official guidance, ask for the reason the device was flagged and what steps are required to resolve the issue.
The NCC provides a toll-free consumer assistance line on 622 and a separate device-verification number, 315. Users can also submit complaints through the NCC Consumer Portal.
Consumers should avoid unofficial agents who promise to remove a device from a blacklist or bypass verification requirements. The NCC also warns users never to disclose a one-time verification code to callers, sellers or other people. Any code required during verification should be entered only through the official process.
What happens if a phone is disconnected?
If a device is eventually barred from Nigerian mobile networks, services that rely on a local SIM, including normal cellular calls, SMS and mobile data, may become unavailable. Wi-Fi connectivity and offline features may still work, depending on the device.
The appropriate response is to establish why the phone was flagged and follow the official resolution process rather than immediately buying another handset.
The NCC says its Device Management System uses device identification information, including IMEI numbers, for compliance checks. It also states that the system does not give the commission access to personal content such as messages, photographs or other files stored on users’ phones.
For now, phone users who receive a warning should verify the result through the official checker and seek clarification if necessary. The reported 30-day warnings should not be taken as proof that every phone owner in Nigeria must register an existing device or replace a handset that has been working normally.
