Bharat Sanchar Nigam Limited (BSNL) has introduced a nationwide network-level anti-spam and anti-smishing service, aiming to provide enhanced security for its mobile subscribers across India. Announced on August 14, 2025, this initiative comes as part of the company’s effort to protect users from phishing attacks, fraudulent SMS messages, and malicious links that can compromise personal information. With increasing reliance on mobile communication for banking, commerce, and daily life, the need for robust safeguards has become more pressing, and BSNL’s latest service seeks to address this challenge comprehensively.

Developed in collaboration with Tanla Platforms, a leading cloud communications company, the new anti-spam system employs advanced technologies such as artificial intelligence, machine learning, natural language processing, and reputation intelligence. These tools work together to identify and block potential threats in real time before they reach subscribers’ devices. The system’s high level of accuracy, exceeding 99%, ensures that most harmful messages are intercepted without affecting legitimate communications. By operating at the network level, BSNL provides a seamless protective layer that does not require any manual intervention or additional applications from users.

The service is designed to detect various forms of spam, including smishing attempts where cybercriminals send deceptive text messages to trick users into revealing sensitive information. On average, the system can detect over 1.5 million scam messages daily and flag tens of thousands of suspicious phone numbers and unique malicious links each month. By targeting these threats proactively, BSNL aims to reduce the risk of financial fraud and enhance overall user trust in mobile communication services.

A key feature of the anti-spam system is its ability to distinguish between harmful content and legitimate messages, such as one-time passwords, banking alerts, government notifications, and other essential communications. This ensures that while users are protected from scams, critical messages continue to be delivered without delay. The implementation aligns with the regulatory framework set by the Telecom Regulatory Authority of India, ensuring compliance with national standards for messaging services.

The protection is automatically enabled for all BSNL subscribers across active service areas, meaning users do not need to download extra software or configure settings manually. This hands-free approach ensures that security measures are applied consistently and effectively across the network. For the company, it also simplifies management and monitoring of the system, allowing BSNL to focus on optimizing performance and expanding coverage.

Beyond immediate protection against scams, BSNL’s initiative represents a broader commitment to enhancing digital safety for its customers. By leveraging modern technologies and partnerships with industry leaders, the telecom provider is taking proactive steps to combat evolving cyber threats. As mobile usage continues to grow in India, such measures are increasingly critical to maintaining trust and promoting secure digital engagement.

Overall, BSNL’s network-level anti-spam service marks a significant advancement in safeguarding mobile communications. It demonstrates a forward-looking approach to cybersecurity, combining automation, intelligence, and widespread accessibility to protect millions of users nationwide. By implementing this innovative system, BSNL aims not only to reduce fraud but also to foster a safer and more reliable mobile ecosystem for all subscribers.
