Airtel's Strategic Embrace of Artificial Intelligence to Combat SMS Fraud on a Large Scale

In the bustling telecom sector of Nigeria, Airtel Nigeria's AI-powered Spam Alert Service has been making waves in the fight against SMS scams. The service, launched in 2023, processed an impressive 22.97 billion SMS messages that year alone[1].

Between March 13 and May 20, 2025, this service flagged over 9.6 million suspected spam messages[1][2]. The system scans about 1.5 billion messages in real time, flagging potential spam based on more than 250 parameters such as sender identity, link structure, message volume, and regional anomalies[1][2].

Key features contributing to its effectiveness include real-time processing speed, dynamic scanning at both the core network and IT system levels, and a scale of flagging that recently increased to about 30 million suspected spam messages[3].

The AI-driven approach sets a new standard in telecom fraud prevention in Nigeria by proactively alerting users and reducing exposure to unsolicited and potentially harmful SMS scams[1][3].

Notably, more than 9.1 million of the flagged messages originated from other networks, while over 528,000 were sent from Airtel numbers[1]. Users can block unsolicited messages entirely via the Do-Not-Disturb (DND) code 2442.

Airtel claims its AI does not read or store SMS content, and all data is encrypted and processed according to industry standards[1]. The AI Spam Alert Service sends real-time alerts when suspicious activity is detected, providing greater protection without intrusive surveillance.

The service scans over 1.5 billion messages in two milliseconds, using a dual-layer approach: one at the network level and another within the IT systems[1]. The AI Spam Alert Service is part of Airtel's proactive strategy to protect subscribers and reinforce trust in their network.

The Nigerian Communications Commission (NCC) oversees spam regulation in the country and introduced stricter rules in July, including registration of bulk SMS sender IDs and a ban on promotional messages between 8 PM and 8 AM[1]. Any organization offering bulk SMS services in Nigeria must now secure a ₦10 million ($6,540) licence valid for five years[1].

SMS scams, while often targeting low amounts, can result in losses of over $100 per victim. Scam messages often impersonate banks, telecom operators, or payment platforms, requesting passwords or transfers under pretenses[1].

In a 2024 consumer protection survey, 58% of respondents in 24 states had received a scam SMS or phone call asking for sensitive information[1]. One in five respondents had been targeted within the last month, and while only 6% of respondents lost money to fraud, the widespread nature of these scams shows how common "smishing" has become.

The surge in SMS scams, coupled with Africa's rising smartphone penetration, made the introduction of the AI Spam Alert Service not only necessary but urgent[1]. Airtel's CEO, Dinesh Balsingh, stated this in a recent interview.

In a country where SMS is the primary channel for banking alerts, government updates, and OTPs for millions, the AI Spam Alert Service plays a crucial role in maintaining the integrity and security of these essential communication channels[1]. Nigerians spent an estimated ₦44.7 billion ($29.8 million) sending texts in 2023[1].

With the continuous evolution of technology and the increasing threat of cybercrime, services like Airtel Nigeria's AI-powered Spam Alert Service are becoming essential tools in the fight against fraud and the protection of consumer privacy.
