Experts have called for stronger laws and stricter regulation to tackle security issues around call masking and Subscriber Identity Module (SIM)-boxing-related fraud in Nigeria, according to the Nation.

Experts Seek Stricter Regulation against Call Masking, SIM-Boxing Fraud

Call masking or refilling is a practice in which international calls are terminated in Nigeria as local numbers, using illegal SIM boxes loaded with several numbers.

It is a deliberate attempt by fraudsters to avoid paying the correct International Termination Rate (ITR) for international calls, paying instead the Local Termination Rate (LTR).

For example, when the number is masked as a local call, an operator pays N3.90 LTR and not N24.40 ITR.

The process allows operators to terminate inbound international telecoms traffic as local calls, so they do not have to pay ITR, which is the interconnection charge set by telecoms traffic carriers as carrier-to-carrier charges.

A SIM Box fraud is a setup where fraudsters install SIM boxes with multiple prepaid SIM cards.

A fraudster can bring calls through VOIP (through the internet) and terminate international calls through local phone numbers from a country, to make it appear as a local call, by initiating the call through a local SIM installed in the SIM box.

About three years ago, when the issue came to the limelight, the Nigerian Communications Commission (NCC) carried out some investigations, leading to the sanctioning and suspension of some operators earlier this year.

Some of these suspensions were later lifted.

The Office of the National Security Adviser (ONSA), the National Intelligence Agency (NIA), the Department of State Services (DSS), and Committees of the House of Representatives and Senate have on several occasions expressed concern about the menace.

While many stakeholders believe that the menace has been nipped in the bud, it has continued to rear its ugly head to the bewilderment of experts and stakeholders.

Ikechukwu Nnamani, president/chief executive officer of Medallion Communications Limited, lamented that it is a subject matter, which NCC should address completely.

Nnamani, who is an executive member of the premier telecom body in Nigeria – the Association of Telecommunications Companies of Nigeria (ATCON), said almost all calls he received recently are masked.

“Sometimes, I don’t pick up calls because I do not know the number only to find out later it was an international call.

“The truth is that I don’t know why this has not been resolved, I expected it to have been solved.

“Honestly, I would not know why. One would have expected them to have sorted all these out by now,” he said.

Chief Deolu Ogunbanjo, president of the National Association of Telecommunications Subscribers of Nigeria (NATCOMS) said there was no need to relent in reporting the menace to the right authority.

He said it could be a plan to ensure that gain accrued to some people. “I don’t know whether call masking favours the operator or it is being done deliberately.

“It is a situation that the telecoms should deal with because it is a technical problem. I think it is some of those unlicensed operators doing all these.

“Some of these operators’ facilities are being tapped into; they need to look into their operations, so they can be taken care of.

“If they are still in the habit of doing it, proper sanctions should be meted out to any erring service provider.

“There should be heavier sanctions. They can’t be short-changing subscribers and at the same time, the government,” he said.

Mr. Ajibola Olude, executive secretary of the Association of Telecommunications Companies of Nigeria (ATCON), believes the issue can be addressed.

“When it comes to technology, you can only address it maximally. It is not as rampant as before and it is an international issue.

“We have addressed it before and we will look at it again.

“About four years ago, when it happened, we deployed all the resources within our capacity to address it and I think it was addressed maximally.

“I have not seen any operator complaining, except now that you are raising the issue, but as far as we know, call-masking is no longer a problem.

“I am going to contact our compliance monitoring to enlighten me about what is going on, but it is no longer an issue,” he said.

Mouka Reuben, director, Public affairs, NCC, said the situation has been tackled before and he does not think it was a major issue again.

He, however, promised that the commission would look into it again to find a way out.

NCC recently put the revenue lost to call-masking and SIM-boxing activities in the country at $3 billion.

This is as telecom operators lamented during the 85th edition of the Telecom Consumer Parliament in Lagos that they were losing about N2.5 million minutes per day to these fraudulent activities.

On actions that had been taken by the commission to combat the menace, Prof Umar Danbatta,  former Executive Vice-Chairman, NCC, said the NCC had tightened the SIM registration process across all networks to reduce the availability of SIM cards for SIM-boxing as well as address the security issues around the availability of pre-registered SIMs.

According to him, the action was necessary as some arrests made in Lagos two weeks ago showed that the perpetrators of SIM-boxing had over 100 SIM cards registered with fictitious names and used them to divert international calls.

IXPN, Nigeria’s leading Internet Exchange Point, is proud to announce a landmark achievement: crossing 1 Terabit per second (1Tbps) in aggregate peak domestic internet traffic for the first time.

Nigeria Hits 1 Terabit Internet Traffic Milestone

This milestone signifies a major leap forward in developing Nigeria’s internet infrastructure and underscores the critical role of local internet infrastructure in driving economic growth, innovation, and connectivity for millions of Nigerians.

“This milestone is more than just a number. It’s a symbol of Nigeria’s digital maturity and our united strides towards becoming a tech-driven nation. By keeping local internet traffic within Nigeria, we reduce costs, improve speeds, and ensure our digital economy thrives with homegrown infrastructure.” said Muhammed Rudman the CEO of IXPN.

“Achieving 1 Tbps is a significant victory for Nigeria’s ICT ecosystem, a breakthrough for domestic internet traffic. It serves as a catalyst, enabling millions of Nigerians to enjoy faster, more affordable, and resilient internet connectivity.”

1 Terabit per second is a game-changer for Africa’s most populous country. To put it in perspective:

  • Mega Video Calls: A speed of 1 Tbps can support over 1 million concurrent Zoom calls, allowing students, entrepreneurs, and professionals to connect and drive Nigeria’s digital revolution.
  • Streaming Frenzy: With 1 Tbps, more than 200,000 people can stream HD Nollywood films or movies on Netflix simultaneously without any buffering or interruptions.
  • Data Superpower: This speed enables the transfer of the entire contents of 50,000 smartphones—including photos, apps, and videos—in just one second.

For Nigeria, hitting this milestone means reducing reliance on international bandwidth, decreasing latency for local services, and strengthening our position as Africa’s digital heartbeat. This milestone is a testament to the power of collaboration, innovation, and the relentless pursuit of a faster, more connected Nigeria.

This accomplishment goes beyond technical advancements; it has significant economic implications. By encouraging local traffic exchange, IXPN reduces dependency on international bandwidth, leading to:

  • Significant Cost Savings: By utilizing local data exchange, Nigerian businesses can save millions of dollars annually on international bandwidth fees.
  • Enhanced Speed and Connectivity: With reduced latency, users experience smoother streaming, gaming, and real-time services, enhancing their overall online experience.
  • Increased Resilience: Strengthening Nigeria’s internet infrastructure protects against global disruptions, ensuring consistent access to vital services such as healthcare and education.
  • Improved Efficiency: Optimizes digital services like fintech, edtech, e-commerce, and e-health, propelling innovation and growth in these sectors.

Surveys conducted among IXPN members over the years have shown a growing percentage of local internet traffic in Nigeria. A recent report indicates that some connected members can localize or domesticate up to 70% of their internet traffic through IXPN.

“As more content providers, ISPs, banks, and public institutions localize their traffic through the IXP, end users benefit directly,” added Raphael Iloka (Marketing Manager). “We’re not just routing data — we’re building the foundation for Nigeria’s digital economy.”

The 1 Tbps peak highlights the remarkable impact of collaboration among all stakeholders. This milestone is a significant achievement not only for IXPN, but for the entire ICT ecosystem.  IXPN deeply appreciates the vital contributions of all stakeholders involved.

To our Members and Partners: Your trust and participation have been essential to our growth. Together, we have established a hub where networks can interconnect, innovate, and thrive.

To the Government and Regulators: We express our sincere appreciation to the Nigerian Communications Commission (NCC) for all its support over the years and its vision of a digitally inclusive Nigeria.

To our Team: We extend our gratitude to our engineers, network administrators, and all other staff who work tirelessly behind the scenes to push boundaries.

To the Global Community: We are grateful to partner organizations like the Internet Society (ISOC). Your support and advocacy in domestic peering empower us all.

Reaching 1 Tbps is just the beginning. As data demands skyrocket with AI, IoT, 5G, and immersive technologies, IXPN is committed to staying ahead of the curve. Here’s how:

  • Scaling Infrastructure: We are investing in advanced hardware and software to support multi-terabit capacities.
  • Enhancing Resilience: We are strengthening our network to ensure uptime, security, and adaptability in an ever-changing digital landscape.
  • Empowering Underserved Communities: We aim to expand our reach to rural areas, bridging the digital divide, and supporting agritech, edtech, and telehealth.
  • Strengthening Africa’s Digital Sovereignty: Partnering with regional IXPs to keep Africa’s data on the continent.
