Union Communications Minister Jyotiraditya Scindia announced on May 2, 2026, that India rolled out and nationwide tested a mobile-based emergency alert system, reaching 12 crore users simultaneously, as a major step to strengthen its disaster response network. Previously on May 2, the Centre formally launched the indigenous Cell Broadcast emergency alert system, designed to send emergency SMS alerts in cases of severe natural calamities or incidents such as gas leaks. This system, branded as the "Extremely Severe Alert" and utilizing cell broadcast for real-time disaster warnings, marks a significant upgrade in India's disaster preparedness framework and features the SACHET platform. On the same day, an emergency alert appeared on mobile phone screens at 11:45 am with accompanying beeps and a readout, leading to confusion among many users. This rollout followed an announcement on May 1, 2026, that India would launch a mobile-based disaster communication system on May 2 to deliver near real-time emergency alerts directly to citizens’ phones, with Union Home Minister Amit Shah and Communications Minister Jyotiraditya Scindia expected to preside.
