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

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.

Airtel Nigeria has concluded its second Customer Forum in Abuja, bringing together a large section of customers including high-volume data subscribers, 5G customers, and key stakeholders in another landmark engagement aimed at addressing concerns around data usage, transparency, and customer experience.

The forum themed “Understanding Your Data and Taking Control 2.0.” aimed to strengthen trust in Nigeria’s rapidly evolving telecommunications landscape. The session also featured inputs from representatives of the Nigerian Communications Commission (NCC).

Delivering the Keynote remarks, Dinesh Balsingh, CEO of Airtel Nigeria, who was represented by Femi Adeniran, Director, Corporate Communications and CSR, emphasised that trust remains the most valuable currency in telecommunications, and Airtel remains committed to strengthening customer confidence through transparency and continuous engagement.

He explained that discussions around data consumption have become increasingly important as digital lifestyles evolve, with smartphones, cloud services, video streaming and emerging artificial intelligence applications significantly influencing data usage patterns.

According to him, Airtel recently introduced the Airtel Data Calculator, an innovative tool designed to help customers estimate their data needs based on online activities such as multimedia streaming, video calls, social media usage, and gaming.

“The purpose of the Airtel Data Calculator is to provide greater visibility, support informed decision-making and place more information directly in the hands of customers. Because transparency should never be viewed as a compliance exercise. Transparency is good business,” he stated.

He further reassured customers that Airtel has no incentive to shortchange subscribers through inaccurate billing, forced spending or unnecessary data depletion, stressing that the company’s growth depends on customer satisfaction, loyalty and trust.

Adeniran also highlighted Airtel’s continued investments in network infrastructure, fibre capacity, digital platforms, artificial intelligence capabilities, customer service systems and workforce development, noting that these investments are aimed at improving service quality and enhancing customer experiences.

Oladokun Oye, Director, Customer Experience, Airtel Nigeria, while welcoming participants to the event, said the forum was created to provide customers with an open platform for education, engagement and problem-solving, noting that the customer remains at the centre of Airtel’s business.

“Data has become central to everyday life, powering work, education, commerce, entertainment, healthcare and countless opportunities. As data usage grows, so too does the desire for greater visibility and understanding.

Today’s conversation is part of an ongoing journey. A journey toward greater transparency. A journey toward deeper understanding. And a journey toward a better customer experience for every Airtel subscriber,” he said.

The forum also featured practical demonstrations on data consumption management, device settings, and usage habits that impact data usage. It also included an interactive session by which Airtel teams provided clarifications and offered feedback to customers.

The Abuja event follows the successful maiden edition held earlier this year in Lagos and aligns with broader industry efforts led by the Nigerian Communications Commission (NCC) to improve consumer awareness, transparency, and confidence within the telecommunications sector.
