NIN-SIM Linkage: Subscribers Complain of Barred Phone Lines

Some telecommunications subscribers on Wednesday expressed displeasure over the barring of their lines by telcos despite having linked their National Identification Numbers (NIN) with their SIM cards.

The subscribers expressed their displeasure in separate interviews with the News Agency of Nigeria in Lagos.
NAN reports that telecommunications (Telcos) operators in Nigeria, including MTN, Airtel, and Globacom, among others, had been directed by their regulatory body, the Nigerian Communications Commission (NCC) to implement full network barring on all phone lines which subscribers had not submitted their NINs and those without verified NINs by February 28, 2024.
The NCC said further that NINs that had been submitted but not verified, such lines were to be barred on or before March 29, 2024, the same as in cases where five or more lines are linked to an unverified NIN.
Similarly, where less than five lines are linked to an unverified NIN, such lines are to be barred on or before April 15, 2024.
In a visit by NAN in Lagos on Tuesday evening to some of the telcos customer service centres, subscribers were complaining about barred lines at all the telcos outlets, but more at the MTN outlets.
The subscribers were displeased that their lines had been barred from making calls even before the February 28 deadline.
Some of them insisted that they had already linked their NINs to their SIM cards as directed by the NCC, so they were surprised that their lines were still barred.
A businessman, Mr. Marcel Okoh, said that a message was sent to his MTN line at the weekend, which he did not take seriously because he had done his NIN-SIM linkage.
Okoh said that two days after the message was sent, he noticed that his SIM had been disconnected, and he could no longer recharge or make calls with his phone.
“The disconnection is uncalled for because I have done what is needed, and I should have been given time to make enquiries.
Similarly, a Fashion Designer, Aisha Alao, who also uses an MTN line, said that she was disconnected by the telco without any notice.
Alao said that it was when she got to one of the MTN outlets that the agents explained to her that she needed to do a NIN-SIM linkage.
Also speaking with NAN, a retired Teacher, Mrs Veronica Maduabunechukwu, said that a disconnection notice was sent to her by Airtel despite having done her NIN-SIM linkage.
“The line has not been disconnected, and I see no reason why it should be barred.
Another MTN subscriber, Mrs Chinenye Agbanusi, said that she had done her NIN-SIM linkage as far back as 2020.
Agbanusi said that she was not pleased with MTN for barring her line after following due process.
She added that Telco should upgrade its systems to avoid recurring issues of barring customers who had already done what was needed.
A Globacom subscriber, Miss Kanyinsola Oje, said that a notice to link her SIM to NIN to avoid disconnection was also sent to her.
She noted that some days after the notice, her line was barred.
However, during the survey, Miss Nkechi, an Agent in one of the Airtel outlets in Ketu, said that subscribers had been coming to the centre to make complaints about their SIM being disconnected.
Similarly, Olumide, a Globacom Agent in Ketu, also confirmed that subscribers had been coming to the outlet to make complaints about their lines being barred since December 2023.
According to him, most of the subscribers insisted that they had done the NIN-SIM linkage before, but were currently having issues.
Olumide said, “The reason for the disconnection could be that the name the subscriber used in registering for their NIN is different from what they used to register their SIM.
“Another issue could be that the line was reassigned to another subscriber, so the name on the SIM could still be the name of the previous owner.
Reacting to the subscribers’ complaints, Mr Funsho Aina, the Senior Manager, External relations, MTN, said that most of the lines that were barred were because no data were found on the lines.
Aina said that it was possible that these subscribers had done the NIN-SIM linkage, but the data filed for NIN might not be the same as what they registered for their SIM.
He said that a discrepancy in data filed for NIN and for SIM could affect its collation.
“Take, for instance, I register my SIM with Funsho, and in registering for the NIN, I use Olufunsho, which is also my name.
“Even if I do the NIN-SIM linkage, in collating by the telco, the technology might not be able to link the names to one person and the line would be disconnected until the discrepancy is corrected,” he said.
Aina, however, said to correct such discrepancies and be reconnected, there were self-help steps that could be taken.
He urged subscribers to go to the portal: https://nin.mtn.ng/nin to create a Virtual NIN (VNIN).
“You can also dial *996*3# on your mobile phone.
“Select option three for Virtual NIN, Enter your NIN to proceed, then enter ‘109071’ as your Enterprise ID.
“Or alternatively, dial *346*3*your 11-digit NIN*109071# to create a VNIN,” Aina said.
The MTN official also explained that it seemed as if MTN subscribers were more affected because MTN had a larger number of subscribers than the other telcos.

Study Shows Blocks in Telegram are Pushing the Underground Out

Modern messengers, such as WhatsApp, Telegram, Signal and others, are often used for illicit purposes. Kaspersky Digital Footprint Intelligence has conducted an in-depth monitoring of over 800 blocked cybercriminal Telegram channels between 2021 and 2024.

While a range of illegal activities continues to be hosted on the platform, its environment has become noticeably more challenging for sustained underground operations.
Telegram’s bot framework and other built-in features make for a low-effort ecosystem for the underworld.
A single bot can simultaneously manage queries, process cryptocurrency payments, and instantly deliver stolen bank cards, info-stealer logs, phishing kits, or DDoS attacks to hundreds of buyers per day, often without operator involvement.
Unlimited, non-expiring file storage eliminates the need for external hosting when distributing multi-gigabyte database dumps or stolen corporate documents. This frictionless automation naturally favours high-volume, low-price, low-skill offerings, such as leaked bank cards or other data, hosting malware, etc.
High-value, trust-dependent deals (for instance, zero-day vulnerability information) still remain on reputation-gated dark-web forums.
Kaspersky researchers found two clear trends related to illegal activities on Telegram. The average lifespan of shadow channels has increased, with the proportion of channels surviving over nine months more than tripling in 2023-2024 compared to 2021–2022. At the same time, Telegram’s blocking activity has risen significantly.
Monthly takedown figures recorded since October 2024 – even at their lowest – are comparable to the peak levels seen throughout 2023, and the overall pace continued to accelerate in 2025. This impedes malicious activities.
Other disadvantages of Telegram for cybercriminals include the lack of default end-to-end (E2E) encryption for chats, the inability to use their own servers for communication (due to the messenger’s centralised infrastructure), and closed server-side code, which makes it impossible to verify its functionality.
As a result, several established underground communities, including the nearly 9,000-member BFRepo group and the Angel Drainer malware-as-a-service operation, have already begun shifting primary activity to other platforms or proprietary messengers, citing repeated disruptions of their activities on Telegram.
“Fraudsters find Telegram a convenient tool for many malicious activities, but the risk-reward balance is clearly shifting. Channels are managing to stay online longer than a couple of years ago, yet the dramatically higher volume of blocks means operators can no longer count on long-term stability.
“When a storefront or service disappears overnight – and sometimes reappears only to be removed again weeks later – building a reliable business becomes much harder. We’re starting to see the early stages of migration as a direct consequence,” comments Vladislav Belousov, Digital Footprint Analyst at Kaspersky.

Galaxy Backbone Marks Two Decades of Powering Nigeria’s Digital Evolution

Galaxy Backbone Limited (GBB), the Federal Government’s leading ICT infrastructure and shared services provider, will mark its 20th anniversary in June 2026 with a grand celebration that reflects two decades of innovation, resilience, and national impact.

Since its inception in 2006, Galaxy Backbone has been at the heart of Nigeria’s digital transformation journey; building the technological foundation that supports modern government operations and public service delivery. What began as a bold vision to connect government has grown into a critical national platform that drives efficiency, transparency, collaboration and innovation across the public sector.
Over the last 20 years, GBB has helped redefine how government works. By providing secure connectivity, enterprise-grade data centre services, cloud platforms, and digital collaboration tools, Galaxy Backbone has enabled Ministries, Departments and Agencies (MDAs) to move from fragmented, paper-based processes to more integrated, technology-driven systems.
This transformation has improved government-to-government coordination, strengthened engagement with businesses, and enhanced the delivery of services to citizens. Today, the digital infrastructure powered by Galaxy Backbone supports thousands of government users, hundreds of institutions, and critical national platforms that Nigerians rely on daily.
A key part of this journey has been the Federal Government of Nigeria’s investment, managed by GBB in robust national infrastructure, high-capacity and world class data centres, fibre-optic connectivity across multiple states, secure hosting services, and shared platforms that have helped government operate more efficiently and responsively. These contributions have played a pivotal role in Nigeria’s progress toward a more digital, agile and citizen-centered public service.
Galaxy Backbone’s impact has earned both national and global recognition. In 2025, the organisation was ranked first overall in the Federal Government Website Performance Scorecard, reflecting its commitment to excellence in digital service delivery. Internationally, GBB, a couple of years ago, received the prestigious United Nations Public Service Award, a testament to its leadership in promoting a whole-of-government approach to digital transformation.
As GBB celebrates two decades of service, this milestone is more than an organisational anniversary; it is a celebration of Nigeria’s digital evolution. It is an opportunity to appreciate how collaboration between government, industry partners, technology providers, and dedicated public servants has helped build a stronger, more connected nation.
The June 2026 anniversary celebration will bring together stakeholders from across the public and private sectors to reflect on the journey so far, acknowledge the partnerships that have shaped this success, and chart an ambitious course for the future. It will highlight how collective effort, shared vision, and innovation have positioned Galaxy Backbone as a strategic national asset.
Looking ahead, Galaxy Backbone remains committed to deepening digital transformation across the country; expanding infrastructure, strengthening cybersecurity, enhancing service delivery, and supporting the Federal Government’s drive for a smarter, more efficient and digitally empowered Nigeria.
At 20 years, Galaxy Backbone stands proud of its past, confident in its present, and inspired by the limitless possibilities ahead.
