Airtel Africa’s AI-powered spam detection service, Spam Alert, has successfully identified and flagged over 205 million spam SMS messages in just six months across 13 of its 14 active markets.
The service, provided free of charge to all Airtel subscribers, automatically detects suspicious SMS messages and prefixes them with “SPAM ALERT” in real-time, eliminating the need for customers to download third-party apps or take extra steps to manage spam.
According to Airtel Africa, the service has been rolled out in Nigeria, Kenya, Zambia, Uganda, Gabon, Congo Brazzaville, Malawi, Madagascar, DRC, Rwanda, Tanzania, Chad, and Niger, with Seychelles expected to join the rollout soon.
Kenya recorded the highest volume of spam, with 68 million messages flagged, followed by Tanzania (47 million) and Zambia (33 million). However, Nigeria experienced the most significant reduction in spam traffic, with an 84% drop in unwanted messages since the system’s deployment. Across all markets, Airtel Africa reported a 12% overall reduction in spam.
“We are proud to pioneer an advanced tech solution powered by AI in tackling spam messages that are a major concern in Africa as smartphone penetration increases. This free service is yet another demonstration of our commitment to consistently innovate to deliver an unmatched experience and safer network to our customers,” said Airtel Africa CEO, Sunil Taldar.
The AI system behind Spam Alert leverages real-time machine learning models to analyze sender behavior, such as frequency and volume of messages, and classify SMS as spam based on dynamic parameters.
The telecom firm affirms it would continue to expand the capabilities of Spam Alert across all markets and adapt the system to counter evolving spam and scam tactics using its AI-driven data models.
With spam SMS often used for fraud, scams, and phishing across telecom networks, Airtel Africa’s initiative marks a significant move towards network-level AI protection that builds trust and security directly into the infrastructure.
