U Mobile, a leading telecommunications provider in Malaysia, has become the first in the country to introduce a network-level scam protection system. This groundbreaking initiative, operational since February 2025, has successfully intercepted and blocked over 265 million fraudulent phone calls and text messages, according to the company’s recent statement.
The scam protection system employs state-of-the-art technology provided by Cellusys, a renowned global provider of mobile operator solutions, including signaling, roaming, and analytics. This technology enables the identification and immediate blocking of suspicious calls and messages at the network level, preventing them from reaching user devices.
According to U Mobile, this new deployment allows for exhaustive screening across 4G and 5G networks. It aims to combat a broad range of digital fraud activities, including scam calls posing as officials or institutions, SMS phishing attempts, spoofed caller identities, and broad fraud campaigns.
U Mobile’s Chief Technology Officer, Woon Ooi Yuen, expressed his pride in the company’s achievement. He stated that the introduction of the nation’s first large-scale, network-level scam protection has yielded significant results, blocking hundreds of millions of fraudulent calls and messages. Yuen emphasized the company’s dedication to improving their network using the latest technology to enhance customer protection across voice, messaging, and data services. He asserted that as U Mobile expands its next-generation 5G network throughout the country, security continues to be a key priority, as reliable connectivity is crucial for a robust Malaysian digital economy.
Brendan Cleary, CEO of Cellusys, expressed his company’s pride in providing the technology that powers this nationwide protection. He emphasized that Cellusys’s technology works with the necessary precision, resilience, and scalability to prevent scams from reaching consumers.
The launch of the scam protection system is timely amid the significant increase in digital fraud incidents in Malaysia. Recent data from the Global Anti-Scam Alliance (GASA) reveals that 73% of Malaysians have reported being targeted by fraudulent calls or messages, ranking the nation as one of the hardest-hit in Southeast Asia.
Cellusys’s platform leverages signaling and behavioral data analyses at the network level to uncover suspicious activities. This allows operators to quickly adapt their defenses as scam techniques evolve, thereby minimizing disruption to legitimate network traffic.
