Google warns smartphone users to disable 2G networks amid rising SMS fraud

In a timely warning issued on June 26, 2025, Google alerted smartphone users about the increasing threat of SMS Blaster fraud. Originating from various countries, this method enables criminals to send malicious text messages directly to phones without going through the mobile carrier networks. This circumvention not only allows fraudsters to bypass anti-spam and anti-fraud measures but also highlights vulnerabilities in cellular communication standards. In conjunction with the warnings from police in the U.K., who have recently jailed a cybercriminal for this type of fraud, it is crucial for users to prioritize their security by adjusting their device settings. The police highlighted a specific case in which a cybercriminal was captured for blasting hundreds of fraudulent SMS messages, evading typical fraud prevention strategies. Their advice emphasizes the necessity for users to remain vigilant against such threats, particularly regarding unsolicited text messages that may masquerade as legitimate communications from reputable brands like PayPal or Netflix. Police caution against falling for offers or alerts that seem overly enticing or dubious, as criminals often exploit users' trust and curiosity, leading to identity theft or financial loss. To mitigate risks, Google recommends that smartphone users disable 2G networks where possible. This protocol has been established as a fundamental step towards safeguarding personal data from exploitation via insecure cellular communications. Disabling 2G capabilities may differ based on device manufacturers and models, so users are encouraged to check their specific settings or engage the new Advanced Protection Mode that is available in Android 16. This recommendation comes as part of Google's emerging strategy to address vulnerabilities in cellular networks and ensure users' security against the evolving landscape of cyber threats. Furthermore, cybersecurity experts have noted an uptick in scams where fraudsters impersonate well-known brands. Trend Micro's recent report supports the observations from Google and law enforcement, suggesting a consistent rise in attempts to deceive users through professional-looking messages. The advice for consumers remains the same: be skeptical of unexpected communications, verify the legitimacy of messages before responding, treat messages from unknown numbers as suspicious, and look out for common signs of scams such as spelling errors or unusual requests for personal information. These measures are crucial in preventing falling prey to mounting threats from cybercriminals around the globe.
