U Mobile has become the first telecommunications provider in Malaysia to roll out full-scale scam protection across its entire network, marking a significant milestone in the country’s fight against phone and SMS fraud. Operating at full scale since February 2025, the initiative is delivered in partnership with Cellusys and has already blocked more than 265 million scam calls and fraudulent SMS attempts from reaching customers.
Unlike device-based spam filters or opt-in applications, U Mobile’s solution operates directly at the network level. By leveraging Cellusys’ Unified Signalling, SMS and Voice Firewall technology, all inbound calls and messages are screened before they ever reach a user’s phone. Suspicious traffic is identified and stopped in real time, preventing scams from being delivered altogether rather than reacting after exposure. This approach has proven effective against a wide range of threats, including scam calls impersonating government authorities and financial institutions, SMS phishing or smishing attacks, spoofed caller IDs and large-scale criminal campaigns targeting Malaysian consumers.
