When Okezie Kelechi lost his SIM card, the one he had used since his secondary school days, he didn’t think much of it.

Gaps on Phone Number Recycling Fuel Identity Theft, Data Breaches- ICIR

He was shocked weeks later to find out it had been reassigned to someone else.

“I had no idea that if your SIM card has been inactive for more than three months, they will resell it,” he wrote on social media.

“They recycled my SIM card and sold it. Same number, I have had it since secondary school.”

Kelechi’s story is far from unique.

Across Nigeria, more people are waking up to the realities of what is known as SIM recycling, a process where telecommunication companies reassign inactive phone numbers to new users. While allowed under existing rules set by the Nigerian Communications Commission (NCC), the practice is now raising serious concerns over data privacy, fraud, and national security.

A regulatory gap with real-life consequences

Experts in Nigeria’s telecommunications and security sectors are increasingly warning that the NCC’s failure to establish stronger oversight of SIM recycling is endangering millions.

“Beyond the data breaches, this issue posed a big threat to national security. I have always maintained the need for a central data system in Nigeria,” said Daniel Makolo, a retired senior official of the Nigerian Immigration Service to The ICIR.

“There’s much more to this if we don’t pay attention to an appropriate central data mining system that gives us a history of each person in the country.”

Ayodele Ajayi, an engineering professor at the Federal University of Technology, Akure, explained the security risks from his own experience.

“I used to have one Airtel number, but I travelled out. Before I came back, it was reallocated to another user,” he said.

Because phone numbers are tied to Bank Verification Numbers (BVNs) and National Identity Numbers (NINs), reassigning them can expose people to identity theft and financial loss.

The NCC should find a way to notify users when their numbers are at risk of being deactivated, Ajayi urged.

He also recounted an incident he witnessed at a bank, “a woman was narrating how she used to have a particular number but lost it. Somebody saw the number and started using it.

The woman said that before she could act, the person who got the number had started using it and had connived with a bank office to almost wipe out all her savings.

“Upon arriving at the bank to check her account balance, she found out that she had only N50,000 left from about N5 million she had saved up.”

Ajayi emphasised that while recycling is a practical move for telcos to manage limited number availability, more caution is needed.

“Let people know so they can migrate their data to another line, particularly now that almost every channel we use is linked to the phone number, including our bank verification number (BVN)”, he stated.

Kelechi recalled that his number was reassigned to another user despite still being active on WhatsApp.

“I used to wonder why random Hausa boys were always messaging me and calling me baby.

He added that “when I finally visited MTN office in Nigeria, I was told the line has been sold to someone else. E pain me, I no go lie.”

Another social media user Elizabeth Kandi, @DrETKandi warning others about the hidden risks of SIM inactivity alleges that when reassigned the new user can have  access to your USSD banking.

“If your Nigerian number was connected to your Nigerian bank accounts for USSD, if you didn’t use it for long, the network provider can disconnect and sell the number to someone else…but that person would be able to access your money via USSD,” Kandi wrote.

Her post underscores the growing fear that recycled numbers, still linked to sensitive services like mobile banking, can open the door to fraud and financial loss

Why do Telcos recycle SIMs?

At a virtual stakeholder meeting in April 2025, NCC Executive Vice Chairman Aminu Maida acknowledged the concern noting that with the evolving landscape, it has become necessary to address emerging challenges that could undermine consumer rights.

He further noted that the Quality-of-Service Business Rules 2024 stipulate that a prepaid line without a revenue-generating event for six months must be deactivated.

This means if a prepaid SIM card goes unused for six months (i.e., no calls, texts, or data use), it must be deactivated.

If the inactivity continues for another six months, the number may be recycled/reallocated to a new user.

In Section 28 of the NCC’s draft business  it is stated that all recycled SIMs must be purged of any NIN attached  to allow a new user to link their own NIN. But real-world cases suggest that in practice, many recycled numbers are not properly sanitised before reassignment.

The business case for SIM recycling

For telecom operators, recycling isn’t just a technical choice, it’s economic.

Gbenga Adebayo, chairman, Association of Licensed Telecoms Operators of Nigeria (ALTON), explained that subscribers do not have ownership rights to SIM cards in their possession, as the telecom operators pay procurement and recurring costs for each registered subscriber.

He further explained that SIM cards are “recycled” to prevent number exhaustion while reducing the cost of generating and maintaining them.

“SIM cards are reassigned to reduce the dormant subscribers, as telcos are profit-oriented organisations,” Adebayo said.

In the exercise of its powers under Section 70 of the NCC Act (2003), the commission made provisions for the development of a new numbering plan for Nigeria. Under the provision, telcos are obligated to pay a sum that is the ‘numbering plan fees’ to maintain their allocated numbers.

Nigeria Communications Commission (NCC) has also confirmed the entry of Mcom which listed 0724 as officially assigned to Mafab.

An insider at Mafab told this reporter that “ We are Nigeria’s first 5G standalone network provider, revolutionizing the telecommunications landscape.  We are driven by a vision to foster a world where possibilities know no bounds with the power of technology”

Recall that the original 5G licence was awarded to Mafab in 2021, with an expectation that rollout would have fully commence by August 2022.

MTN Nigeria, the other winner of the license adhered to this timeline and deployed its 5G across major cities like Lagos, Abuja, and Port Harcourt.

Mafab on the other hand, requested and was granted an extension of time, which it have finally taken advantage of by the recent launch.

NCC to Name, Shame Telecom Infrastructure Vandals

Nigerian Communications Commission (NCC) has vowed to intensify its collaboration with security agencies to arrest and prosecute individuals vandalising the country’s Critical National Information Infrastructure (CNII).

NCC to Name, Shame Telecom Infrastructure Vandals

Auwal Abdullahi, head of Quality of Service at the NCC, said this during a media engagement held in Abuja.

The move comes on the heels of the recent signing of the “Designation and Protection of Critical National Information Infrastructure Order, 2024” by President Bola Tinubu.

The Order is aimed at protecting essential digital and communication systems from cyberattacks, vandalism, and related disruptions.

Speaking on the development, Abdullahi said: “The Critical National Information Infrastructure (CNII) Act has provisions for prosecution, and the operationalisation of CNII falls under the purview of the Office of the National Security Adviser (ONSA). Anyone found liable for damaging or disrupting CNII will be prosecuted going forward. We are working with relevant agencies like the Nigeria Security and Civil Defence Corps (NSCDC) to tackle these problems and prosecute offenders.”

He recounted that some telecom operators recorded significant financial losses two years ago, largely due to exchange rate pressures and infrastructure vandalism.

“About two years ago, we noticed a situation where some of our key telecom operators were recording massive losses. Despite increasing revenues, they were struggling with heavy forex-related obligations that ate into their revenues. This led to poor quality of service,” he said.

According to him, the recent tariff adjustments have placed the industry back on a path to profitability and renewed investment.

“As a result, they are able to reinvest in their networks, which will lead to better quality of service and experience. We expect investments in the industry to increase significantly this year, more than what was seen in the last two years. The Nigerian telecoms industry has great promise, evident in its revenue growth and service delivery, despite the recent challenges,” he added

Also speaking at the event, Aminu Maida, executive vice chairman and CEO of the NCC,  reassured stakeholders that the Commission remains committed to driving improvements in network quality across the country.

Represented by Mrs. Nnena Ukoha, acting head of Public Affairs, Maida challenged journalists to act on the knowledge shared at the forum.

“This is not for you alone. You now have this information, do not just sit on it. For instance, you were given figures on fiber cuts and thefts affecting NCC. Who is responsible for those infrastructures? The NSCDC. Ask them: ‘Of all these incidents, what are you doing about them? How many people have been prosecuted?’ Every state has legal departments. Go and ask them: ‘What are you doing to protect critical infrastructure?’ he queried.

USSD: 13 Banks Clear Debts – ALTON

Published

Association of Licensed Telecommunications Companies in Nigeria (ALTON) has revealed that 13 commercial banks have fully settled their outstanding Unstructured Supplementary Service Data (USSD) service debts to Mobile Network Operators (MNOs).

USSD: 13 Banks Clear Debts - ALTON

Gbenga Adebayo, chairman, ALTON

The remaining three banks are nearing completion of their payments, having cleared over 95% of their respective debts, according to Gbenga Adebayo, chairman, ALTON.

This resolution paves the way for a new billing system for USSD banking transactions.

Going forward, charges for these services will be debited directly from customers’ airtime accounts.

The update on debt settlements and the upcoming billing model were discussed , during the ‘ASK the Exec’ online meeting anchored by MTN.

Participants included Lynda Saint-Nwafor, chief enterprise business officer at MTN and  Adebayo.

According to the ALTON Chairman, there has been substantial progress in resolving the long-standing debt issue.

“As of January, the outstanding debt from banks to MNOs for USSD services was N180 billion. Of the 17 banks with pre-API outstanding payments (excluding Heritage Bank, which is insolvent), 13 have fully settled their debts, and the remaining three are in the final stages of installment payments, with over 95% of the debt cleared”, he explained to journalists present at the call.

The clearance of historical debt is crucial as the industry moves to a new operational model.

“Banks with outstanding debts will not be excluded from the new system; they can either migrate to end-user billing once their debts are cleared or choose to remain on the old corporate billing model, provided they settle their outstanding obligations”, Adebayo pointed out.

Since 2021, collaborative efforts between the telecommunications and banking industries, supported by their regulators, have aimed to standardize charges for USSD banking transactions, resulting in a unified fee of N6.98 per transaction.

Saint-Nwafor, explained the upcoming change: “The most significant change is the transition to end-user billing, where customers will now be billed for USSD transactions directly from their airtime accounts instead of their bank accounts. This means deductions will no longer occur from bank balances but from airtime balances held with MNOs.”

Previously, banks directly debited customers’ bank accounts, a system that presented challenges regarding transparency and control.

To address this, an Application Programming Interface (API) was developed, granting banks full control over their USSD channels. For instance, a bank like GTBank with the USSD code *737# can now ensure a customer’s number is accepted by the bank before a transaction proceeds, after which the bank applies the N6.98 charge.

MNOs like MTN simply facilitate the connection, earning their N6.98 fee for providing the channel.

To ensure a smooth transition and consistent experience, a standardized process for end-user billing has been implemented across all operators and banks: Consent Message: Customers dialing a bank’s USSD code will receive a clear consent message informing them of the N6.98 deduction from their airtime and requesting acceptance.

Aggregator Communication: Upon acceptance, the MNO will contact a USSD aggregator to confirm the bank’s availability, preventing billing for unfulfilled services. Transaction and Billing: Once the bank confirms readiness, the MNO connects the customer and bills the airtime account.

All MNOs have also unified their messaging to customers, providing consistent communication on service levels and transaction outcomes, clarifying if a transaction failed due to issues on the bank’s end or the telco’s side.

Crucially, telco service purchases (airtime and data) from banks are zero-rated when customers use direct strings (e.g., dialing *737*10000# for N10,000 airtime instead of the generic *737#).

This informs both the MNO and the bank of the specific intent, making these transactions free.

Customers are strongly encouraged to use these direct strings to avoid charges, and extensive communication campaigns are planned. Any instance of double deduction (from both airtime and bank accounts) should be reported to the customer’s bank.

Adebayo addressed several key questions, reassuring the public about the implications for consumers and businesses.

He noted that for consumers, the shift to end-user billing has a zero net effect on cost, as they were already paying the N6.98 fee, albeit from their bank accounts.

Transparency and accountability are enhanced through standardized consent messages, inter-industry agreements, and MNOs’ commitment to provide monthly performance statistics to regulators.

“If a transaction fails due to MNO network issues, the customer will not be billed, or any deduction will be reversed. However, if the failure originates from the bank’s end (e.g., insufficient bank balance, bank system downtime), the customer will still be billed, with the reason for failure communicated”, ALTON Chairman explained.

The concern about USSD usage limiting access for those in unbanked areas or without airtime was also addressed.

“The N6.98 charge is considerably lower than alternative transport costs to physical banking points. Furthermore, customers can purchase airtime from their bank accounts at zero cost using direct strings, even if they have no airtime, as long as they have funds in their bank account. USSD is seen as a convenience channel, with all stakeholders contributing to the cost of providing financial services”, Adebayo stated.
