80m Calls in 3 Days: The Phone Scammer Lifecycle- Report

Robocalls continue to plague consumers, but what does the life of a phone scammer look like? Jonathan Nelson, Product Manager in the Reputation Service Unit at Hiya shares a glimpse of the work undertaken by their state of the art unit dedicated to detecting and monitoring spam numbers.

Phone Reputation Service engines constantly evaluate phone number behaviour to sniff out spammers and scammers.

The service runs in real time, observing traffic patterns and collecting reports from users provided directly or via partnerships, as well as from public sources such as the FCC Consumer Complaints database.

In all, a new high-volume scammer coming online is detected within about 15 minutes of their first scam call.

This service runs fairly consistently with approximately 100,000 spammers being tracked within the +1 dialing code (which includes the United States, Canada, and much of the Caribbean). During the five months prior to the holidays, the total active spam number count fluctuated by about 10%.

(The holiday season is excluded from analysis because every year, the spammers and scammers take the holidays off just like the rest of us.)

Within this fluctuation, there is significant turnover within the numbers themselves. On average, approximately 5,000 numbers join the spam list every day, replacing roughly the same amount of phone numbers that have stopped being active.

While there is a consistent amount of phone numbers being used for scam at any one time, the numbers themselves are constantly rotating in and out to help scammers avoid detection.

To get a better grasp on how these scam numbers behave and how long they remain active, let’s take a closer look at 13,000 phone numbers which arrived as new spammers over a three-day period.

The goal is to explore the space of “turn and burn” scam numbers, which do a large and very brief batch of scam activity.

It’s worth repeating: Over 1 in 10 of every new spam number detected is a number that will only exist for, at most, a few days.

In fact, 72 of them aren’t even valid phone numbers. This almost certainly indicates “spoofing”, a scammer who hides their actual phone number in favor of a fake one. Phone numbers in the United States must abide by the rules of the “North American Numbering Plan”, which defines area codes and 10-digit phone numbers for the US, Canada, and over 20 other countries within the Caribbean.

This numbering plan has some special rules such as which digit can be a ‘1’, not to mention which area codes have been assigned. Some scammers don’t bother to check if their pretend number is valid before they start using it.

It is estimated these numbers created over 80 million calls in three days. What were they doing? The best place to look is user reports. Every month, well over half a million reports are received from users who are looking to help inform and protect others receiving the same calls.

The ~1,500 turn-and-burn scammer numbers have together amassed nearly 15,000 comments against them. 92% of these reports arrived within a five-day window around the analyzed segment. Most of these numbers have little to no history before being used for the scam campaign. (User reports go back to early 2010).

To get an overall picture of the complaints, all the comments left against these numbers were fed into a word cloud. (above)

Unfortunately, the one statistic that cannot be measured is how many innocent people fall victim to these scams.

Hopefully, spam blocking services can continue to provide some advance warning and make sure everyone stays suspicious of unexpected threats or unlikely offers.

The best way to bring an end to the influx of scam activity is to make sure it’s not profitable for the scammers.

Africa to get AI Data Centres Through Three-way Partnership

Published

Kindly share this post

Localised, industrial-grade artificial intelligence (AI) data centre infrastructure will be delivered across Africa and the Global South, following a strategic alliance between sovereign AI infrastructure company Amini, electronics manufacturing giant Hon Hai Technology Group (Foxconn) and French digital firm Bull.

The three-way partnership aims to close the sovereign compute gap by allowing governments, telecommunications operators, financial institutions and energy companies to acquire and operate computing systems domestically.

Africa’s digital economy is projected to reach $1.5 trillion by 2030, which is driving regional demand for AI-enabled services across public administration, energy and finance, the parties say.

However, advanced cloud and AI processing capabilities have historically remained concentrated within a small number of external providers. The partnership seeks to establish locally anchored infrastructure, enabling domestic organisations to retain control over data and digital sovereignty.

Under the agreement, Amini will drive local market engagement and deployment, leveraging its existing platforms for locally anchored data capacity.

Foxconn will provide specialised hardware, server architecture and modular data centre technologies in its first dedicated infrastructure initiative focused on African markets.

Bull integrates its expertise in high-performance computing, quantum computing and emerging-market digital capacity. By operating independent systems, critical national sectors can bypass reliance on external platform architectures.

Financial entities can deploy independent credit, risk assessment and financial inclusion algorithms, while energy providers can implement localised machine learning for predictive maintenance and national grid optimisation.

“AI is becoming foundational infrastructure for every economy, yet most of the world still lacks the compute capacity required to participate on its own terms,” said Kate Kallot, founder and CEO of Amini. “This partnership ensures that Africa and the Global South can acquire, own and operate AI infrastructure locally, with sovereignty and long-term economic value at its core.”

Alexandre Jouys, chief commercial officer and head of Southern Europe, Middle East and Africa at Bull, added that Africa and more generally the Global South have the potential to emerge as a global-scale AI hub, by continuing to build regional computing capacity and supply chain independence.

Nigerian Communications Commission (NCC) says ongoing investments and regulatory interventions in the telecommunications sector are expected to address persistent quality of service challenges across the country.

NCC Says Telecom Industry on Course to Improve Quality of Service

NCC

In a statement signed by the Head of Public Affairs, Nnenna Ukoha, on Wednesday, the commission acknowledged public concerns over dropped calls, slow internet speeds, unstable data services and service disruptions affecting consumers.

The commission said telecommunications services had become central to work, education, business, access to essential services and social connectivity, adding that consumers deserved reliable services and value for money.

According to the NCC, improving quality of service has remained a major regulatory priority over the past two years.

It said the commission had intensified monitoring of Mobile Network Operators, Internet Service Providers and Tower Companies, while strengthening data-driven oversight and stakeholder engagement to address structural challenges affecting service delivery.

The commission disclosed that the sector was undergoing one of its largest network expansion and modernisation phases in recent years following a prolonged period of under-investment.

It said Mobile Network Operators invested more than N2.13 trillion in network infrastructure and upgrades in 2025, while Tower Companies invested an additional N373.8 billion.

According to the NCC, the investments supported the addition and upgrade of more than 2,800 telecommunications sites nationwide to improve network coverage and capacity.

The commission said interventions included deployment of additional 4G and 5G infrastructure, fibre backhaul expansion, targeted deployments in high-demand urban areas, expansion into underserved communities and equipment upgrades.

It added that operators had committed to adding or upgrading more than 12,000 sites in 2026, with nearly 3,000 already completed.

The NCC also said over 730 additional 5G sites had been deployed across 27 states in 2026.

The commission noted that 4G penetration rose from 45 per cent in January 2024 to 54 per cent currently, while national median download speeds improved from 16.5Mbps to 20Mbps within the same period.

It further said power availability at telecom towers improved from a national average of 99.3 per cent in January 2025 to 99.7 per cent.

According to the commission, spectrum reallocation among major operators and spectrum block rearrangements were also being implemented to improve network efficiency and service performance.

The NCC, however, acknowledged persistent external challenges affecting service quality, including vandalism, theft of telecom equipment, fibre cuts, power disruptions and access denial for maintenance.

It disclosed that more than 27,000 avoidable fibre-cut incidents linked mainly to road construction and vandalism were recorded in 2025.

The commission said it was collaborating with the Office of the National Security Adviser and other stakeholders to implement the Presidential Order on Critical National Information Infrastructure.

It added that operators had been mandated to notify consumers of major service outages promptly and restore services within specified timeframes.

The NCC said enforcement of the updated Quality of Service Regulations 2024 commenced in November 2025, including consumer compensation measures for poor service quality and additional investment obligations on Tower Companies.

It warned that regulatory action would continue against operators that fail to deliver measurable improvements.

The commission reaffirmed its commitment to ensuring affordable, reliable and high-quality telecommunications services for all Nigerians.
