KUALA LUMPUR: U Mobile Sdn Bhd has blocked more than 265 million scam calls and fraudulent short message service (SMS) attempts nationwide since rolling out full-scale network-level scam protection across its 4G and 5G network as of December 2025.
In a joint statement, U Mobile and Cellusys said the initiative, powered by Cellusys’ advanced firewall technology, has enabled the telecommunications company (telco) to block scam attempts via screening all inbound calls and SMS at the network level, preventing suspicious communications from reaching customers' devices.
"The solution has protected U Mobile customers from scam calls impersonating authorities and institutions, SMS phishing attacks (smishing), spoofed or manipulated caller identities and high-volume criminal campaigns targeting Malaysian consumers,” they said.
U Mobile chief technology officer Woon Ooi Yuen said that embedding the advanced scam protection solution from Cellusys reflects the telco’s commitment to safeguarding its customers against fraudulent activities.
"We will continue to improve our network through technology to better protect customers across voice, messaging and data services.
"As we expand our next-generation 5G network nationwide, security remains a core priority, because trusted connectivity is essential to a resilient digital economy,” he said.
Meanwhile, Cellusys chief executive officer Brendan Cleary said U Mobile’s deployment sets a benchmark for scam prevention in Malaysia and the wider region.
"This deployment demonstrates what can be achieved when operators commit to proven, real-world defences rather than future roadmaps,” he said.
According to the statement, citing the Global Anti-Scam Alliance’s findings, 73 per cent of Malaysians have reported experiencing scam calls or fraudulent SMS, among the highest rates in Southeast Asia, with criminal groups increasingly targeting households, senior citizens, and vulnerable individuals. - Bernama
