Smart Communications has blocked more than 955 million fraud- and phishing-related SMS messages and blacklisted nearly 200,000 mobile numbers suspected of fraud in the first quarter of 2026. This indicates that Philippine mobile networks continue to face large-scale malicious SMS campaigns, with operators working to reduce the reach of fraudulent messages to end users through network filtering, number remediation, and risk intelligence analysis.
Fraudulent SMS messages often impersonate banks, e-wallets, e-commerce platforms, courier companies, government agencies, telecom operators, or well-known brands, creating a sense of urgency under pretexts such as account abnormalities, refunds, prize wins, package issues, or identity verification. Attackers may attempt to trick users into clicking malicious links, disclosing one-time passwords (OTP), account passwords, payment details, or other identity information to commit fund theft or account takeover. Smart reminds users not to respond to suspicious messages, nor to disclose OTPs, PINs, passwords, or bank card details to any caller, SMS sender, or social media account.
In addition to filtering SMS and remediating fraud-related numbers, Smart warns that criminals may use fake base stations or rogue cell sites to mimic legitimate network signals, bypass conventional telecom networks, and push phishing SMS directly to nearby devices. Therefore, network-level interception is no substitute for user verification: users should confirm the authenticity of information through the official apps, official websites, and customer service hotlines of banks, platforms, or government agencies.
User reporting remains a critical part of the anti-fraud ecosystem. Smart advises users to submit suspicious SMS via the HULISCAM reporting channel, providing details such as the sender number, date of receipt, SMS content, and location of receipt; the operator can then conduct investigations and take blocking measures against numbers confirmed to be involved in fraud.
For enterprises, the scale of over 955 million blocked messages highlights that legitimate business SMS requires greater focus on verifiable sender identities, content accuracy, and link security. Banks, retail, e-commerce, and service platforms should use certified enterprise messaging channels, refrain from sending transactional or marketing notifications containing links via ordinary personal numbers, and make official communication methods available for user verification public on their official websites, apps, and customer service channels.
