Govt’s new disaster warning system takes citizens by surprise

If your phone buzzed on Saturday with an urgent-sounding Government alert, you were not alone. Mobile users across India received an unusual tone on their phones, leaving people confused as to what had happened, followed by a warning message flashing on their screens on Saturday. The unexpected alert was part of a nationwide test conducted by the Central Government to evaluate a new mobile-based disaster communication system designed to deliver real-time emergency warnings.

The Department of Telecommunications (DoT), Ministry of Communications, in collaboration with the National Disaster Management Authority (NDMA), on Saturday sent an alert to almost all citizens around 11:42 to test the system. The test message read, “Extremely Severe Alert. India launched Cell Broadcast using indigenous technology, for instant disaster alerting service for its citizens. Alert citizens, safe nation. No action is required by the public upon receipt of this message. This is a test message — Government of India”.

Officials have clarified that there is no reason for concern, as the alerts currently being received on mobile phones are part of a trial phase and not actual emergency warnings.

Union Communications Minister Jyotiraditya Scindia rolled out the Cell Broadcast Alert System with support from the National Disaster Management Authority, under the guidance of Union Home Minister Amit Shah.

“Union Minister for Communications and Development of North Eastern Region, Jyotiraditya Scindia, on Saturday launched the Cell Broadcast Alert System, developed indigenously by C-DOT in collaboration with the National Disaster Management Authority (NDMA), under the guidance of Home Minister Amit Shah,” an official statement said.

Speaking on the occasion, Scindia said, “The launch of the Cell Broadcast System marks a transformative step in India’s disaster management framework, reflecting our shift from a reactive to a proactive approach in safeguarding citizens. By leveraging advanced telecom technologies, CBS enables near real-time, geo-targeted alerts to reach millions instantly, ensuring that no individual is left behind. This indigenous, globally benchmarked solution strengthens our preparedness, enhances response capabilities, and reinforces our commitment to building a safer, more resilient India.”

During the event, a presentation on disaster preparedness and the ongoing initiatives of NDMA was made to the Union Minister by Anuj Sharma, Additional Secretary of the Ministry of Home Affairs.

Through this system, critical information related to disasters, emergencies, and public safety will be transmitted directly and instantly to citizens’ mobile phones, the statement said.

The system is based on the Common Alerting Protocol (CAP) as recommended by the UN body International Telecommunication Union. Designed to deliver critical information instantly during disasters or public safety emergencies, the system works without requiring internet access or mobile apps.

The new Cell Broadcast Solution (CBS) technology represents a significant upgrade over traditional SMS alerts. Unlike regular SMS notifications, Cell Broadcast alerts are designed to grab immediate attention. CBS offers precise geo-targeting capabilities, enabling alerts to be disseminated at the level of individual cell towers or clusters, while also allowing scalability to cover larger geographic areas.

The system enables real-time, multilingual alerts that provide critical time for protective action in disasters such as flash floods and gas leaks. Supported across 2G to 5G networks, it ensures wide reach in both urban and rural areas, including last-mile and roaming populations. By enabling direct, official communication, it strengthens disaster management, drives quick response, reduces panic, and enhances public trust and compliance.

Additionally, alerts are delivered as priority notifications, appearing as pop-up messages accompanied by distinct loud tones, with message text read aloud on supported mobile handsets.

The Government informed that the NDMA has successfully operationalised the Integrated Alert System (SACHET), developed by the Centre for Development of Telematics (C-DOT). It is based on the Common Alerting Protocol (CAP), as recommended by the International Telecommunication Union. Integrated with the CAP-based SACHET platform, it allows rapid and standardised dissemination of alerts. It overcomes the limitations of traditional SMS-based systems, ensuring that critical information can be disseminated quickly and efficiently to large populations within targeted areas.

When triggered, they override normal phone settings, producing a sharp alarm sound along with a prominent on-screen message, ensuring that even users with their devices on silent or do-not-disturb modes are notified. The centre informed that it is currently operational across all 36 States and union Territories, delivering disaster and emergency-related alerts via SMS to mobile users within geo-targeted areas. It has been extensively utilised by disaster management authorities, enabling the dissemination of over 134 billion message alerts to date, in more than 19 languages during natural disasters, weather warnings, and cyclonic events.
