NEW DELHI: If your phone screamed at you today, do not panic. The Government of India is conducting a nationwide test of a new cell broadcast emergency alert system, built on indigenous technology, that pushes real-time disaster warnings to every mobile phone in a targeted area simultaneously, without clogging networks or requiring an internet connection.
The alert that flashed across screens read: “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.” A Hindi version appeared below it.
The initiative is being run by the Department of Telecommunications under the Ministry of Communications, in partnership with the National Disaster Management Authority. The system is built on a platform called SACHET, developed by the Centre for Development of Telematics, a government-backed telecom research body, and is entirely home-grown, in keeping with India’s push to build indigenous telecom infrastructure.
Unlike conventional SMS alerts, cell broadcast technology blankets every handset within a defined geographic zone at once, making it far more effective in genuine emergencies when voice and data networks are typically overwhelmed. The system is designed to work across tsunamis, earthquakes, lightning strikes and man-made disasters such as gas leaks and chemical hazards, reaching affected citizens within seconds.
During the trial period, users may receive the test message more than once across different networks. That too is normal. Those who wish to check or manage their settings can do so under Settings, then Safety and Emergency, then Wireless Emergency Alerts, then Test Alerts.
Once trials conclude and the system launches formally, it will fire automatically, no human intervention needed, the moment disaster strikes.
India has built the siren. Now it just needs to make sure everyone can hear it.
