Suddenly, Alarms Rang on Millions of Phones: Why Did Indians Receive This Alert, and What Exactly Is It?

BS News Agency: The entire nation is abuzz following the sudden blaring of alarms on mobile phones. Did your phone ring, and did you receive an emergency alert message? If so, do not panic! On Saturday afternoon, millions of users received an alert message as part of a nationwide test of the Cell Broadcast Alert System, conducted by the National Disaster Management Authority (NDMA). This initiative was undertaken as part of the government's efforts to strengthen emergency communication systems. According to a report by *The Hindu*, this test was conducted in the capital cities of all states and Union Territories, with the exception of Delhi-NCR, border areas, and states currently undergoing election processes.

Labeled as 'Extremely Severe Alerts,' this warning message was dispatched by the NDMA. It read: "India has launched Cell Broadcast using indigenous technology to provide immediate disaster alert services to its citizens. Alert Citizens, Protect the Nation. The public is not required to take any action upon receiving this message. This is a test message. — Government of India." This initiative is being jointly managed by the Department of Telecommunications (DoT)—under the Ministry of Communications—and the National Disaster Management Authority (NDMA). This system is integrated with an alert platform named SACHET, developed by the Centre for Development of Telematics (C-DOT).

Didn't Receive the Alert? Here Is the Reason

Developed by C-DOT and operated through the SACHET platform, this system is capable of instantly reaching all compatible devices within a specific geographical area during a disaster—overriding 'Silent' and 'Do Not Disturb' settings. These "test messages" were received only on those mobile devices where the Cell Broadcast Test Channel was enabled (users can toggle these alerts on or off on their mobile devices by following this menu path: Settings → Safety & Emergency → Wireless Emergency Alerts → Test Alerts).

Further Alerts

According to a statement from the Ministry of Communications, recipients may receive multiple messages over the coming days as part of a testing process designed to ensure the proper functioning of the entire mobile network infrastructure. During this period, the general public may receive test messages on their mobile devices in English, Hindi, and regional languages. Authorities have stated that users may receive these alert messages multiple times as mobile towers across various networks are being evaluated; this is normal and expected.

To date, the Disaster Management Authority has utilized this system extensively. According to an official statement, this mechanism has enabled the delivery of over 134 billion SMS alerts—in more than 19 Indian languages—regarding natural disasters, weather warnings, and cyclones.
