Nigerian police are warning about a SIM registration scam that runs through informal roadside kiosks rather than official telecom outlets, and it ends with innocent people identified as suspects in kidnappings and fraud cases they had nothing to do with. In a video advisory, SP Bright Edafe, public relations officer of the Delta State Police Command, laid out how it works: a customer approaches an informal agent to register or replace a SIM, hands over sensitive identity details including their National Identification Number, full name and background information, and the agent quietly registers a completely different SIM card using that stolen information instead. The customer gets told the network failed and is sent away empty-handed, while the secretly registered line, now carrying a real person’s NIN and identity, gets sold on the black market to criminal syndicates running kidnapping, extortion and cybercrime operations.
This is a distinct threat from the SIM swap fraud Nigerians have been warned about for years, and the difference matters. A SIM swap hijacks a victim’s existing phone number, usually through a compromised or bribed telecom agent, so a fraudster can intercept one-time passwords and drain a bank account directly. This scheme doesn’t touch the victim’s real number or bank account at all. It manufactures an entirely new SIM, criminal-linked from the moment it’s activated, that carries someone else’s verified identity as its registered owner. The payoff for the fraudster isn’t immediate cash, it’s a clean, traceable-sounding identity to attach to a line that will later be used for ransom calls or extortion demands. Both schemes exploit the same weak point, informal or unverified SIM registration, but this one turns the victim into a suspect rather than a drained account.
That legal exposure is the part Edafe spent the most time on. Nigeria’s NIN-SIM linkage system exists so that digital forensics can trace a criminal phone call back to a real, verified identity, which is precisely what makes this scam so damaging once it works. “If they use your number to defraud somebody or demand ransom money in a kidnapping case, it will be very difficult to claim ignorance,” Edafe said, adding that unfamiliarity with how the scam works offers no legal protection. “Whatever offence they commit with that SIM card, bearing your NIN, your name, and your details, it becomes your responsibility to clear yourself, and it will be difficult to prove that you didn’t commit the crime,” he warned, noting that a line flagged in an active criminal investigation is also simply a dangerous thing to be attached to, regardless of guilt.
The scam also rides on top of a recurring pattern in how Nigeria enforces NIN-SIM compliance. The country has run multiple disconnection drives over the past several years, cutting off tens of millions of unlinked lines at a time and giving subscribers compressed deadlines to get registered or relinked, including enforcement activity as recently as this year. Every one of those deadlines pushes a wave of people toward whatever registration point is fastest, official or not, which is exactly the rushed moment an informal kiosk starts looking like a reasonable shortcut instead of a risk.
It’s genuinely hard to pin down how big this specific problem is. Identity theft is widely cited as accounting for 63% of digital financial crime across Africa, with losses estimated near $4 billion a year, but that figure circulates across multiple outlets without a clearly identified original study behind it, so it’s worth treating as a directional estimate of scale rather than a precise, audited number. What’s better documented is that SIM-related fraud broadly, including the separate SIM swap method, has been one of the continent’s most persistent fraud categories for years, and Nigeria’s telecom regulator has been formally reminding operators and agents about registration-related identity theft risks since at least 2022 without fully closing the informal-agent gap that enables schemes like this one.
Edafe’s advice is straightforward and worth repeating plainly: register or replace a SIM only at an official MTN, Airtel, Globacom or 9mobile service centre, not a roadside kiosk; periodically ask your network operator for a full list of numbers registered against your NIN, since one you don’t recognize may already exist; and if you find one, request its formal disconnection and delisting immediately rather than assuming it will sort itself out. None of that fixes the structural problem, which is that Nigeria built a system to make phone numbers traceable to real identities for security reasons, and that same traceability is exactly what turns an unsuspecting victim into the fall guy the moment a criminal syndicate is holding a line registered in their name. Closing that gap means tightening who gets to collect a NIN and register a SIM in the first place, not just warning people after the fact.
