**Key Points / Main Content**
**System Development and Technology**
* The disaster communication systems are a collaborative effort between the Department of Telecommunications (DoT) and the National Disaster Management Authority (NDMA).
* The Centre for Development of Telematics (C-DOT) is responsible for the indigenous development and implementation of the Cell Broadcast (CB) technology.
* The systems utilize the Common Alerting Protocol (CAP) as recommended by the International Telecommunication Union.
**Integrated Alert System (SACHET)**
* The SACHET system is already operational across all 36 States and Union Territories in India.
* It has disseminated over 134 billion SMS alerts to date, covering natural disasters and weather warnings in more than 19 Indian languages.
* The system targets mobile users within specific geographic areas to provide localized information.
**Cell Broadcast (CB) Capabilities**

* It provides near real-time delivery for time-critical events such as tsunamis, earthquakes, lightning strikes, and man-made emergencies like gas leaks.
* This technology works alongside existing SMS-based alerts to strengthen the national disaster response.
**Launch and Testing Details**
* The nationwide launch exercise is scheduled for May 2, 2026.
* Test messages will be broadcast in English, Hindi, and various regional languages.
* The testing phase specifically targets mobile handsets in Delhi, NCR, and all state capital cities.

Union Home Minister Shri Amit Shah, in the august presence of Union Minister of Communications Shri
Jyotiraditya Scindia will be launching mobile-based disaster communication systems on 2nd May 2026.
The system has been developed by the Department of Telecommunications (DoT), Ministry of
Communications, in collaboration with the National Disaster Management Authority (NDMA),
Government of India to ensure timely dissemination of critical information to its citizens.
NDMA has successfully operationalized the Integrated Alert System (SACHET), developed by the Centre
for Development of Telematics (C-DOT), the premier R&D centre of the Department of
Telecommunications. The system is based on the Common Alerting Protocol (CAP), as recommended by
the International Telecommunication Union. It is currently operational across all 36 States and Union
Territories of India and delivers disaster and emergency related alerts via SMS to mobile users within geo-
targeted areas.
The system has been extensively utilized by disaster management authorities, enabling the dissemination
of over 134 billion SMS alerts, till date, in more than 19 Indian languages during natural disasters,
weather warnings, and cyclonic events.
To further strengthen alert dissemination in time-critical situations, such as tsunamis, earthquakes,
lightning strikes and man-made emergencies like gas leaks or chemical hazards, Cell Broadcast (CB)
technology has been introduced alongside SMS. In a Cell Broadcast System, alerts are transmitted to all
mobile devices within a defined geographic area simultaneously, ensuring near real-time delivery of the
alerts. C-DOT has been entrusted with the indigenous development and implementation of this Cell
Broadcast-based public emergency alert system.
The following message will be sent to mobile handsets in all capital cities of India along with Delhi and
NCR as launch exercise. The messages will be sent in English, Hindi and Regional languages:“India, launches 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.”
