On May 2, a significant test of India's new Cell Broadcast System startled millions of residents in cities like Delhi and Mumbai, as their phones emitted a loud alert reading 'Extremely Severe.' This alert was part of a rehearsal for a disaster alerting service developed by the Centre for Development of Telematics (C-DOT). Unlike traditional SMS, the Cell Broadcast System sends simultaneous alerts to all mobile devices within a specific geographic area, ensuring rapid communication during emergencies. This system is crucial for cities prone to natural disasters, such as tsunamis and earthquakes. The test was focused on Delhi NCR and the capitals of all states and union territories, deliberately excluding border areas and states with upcoming elections. The alert was delivered in multiple languages and designed to capture attention even if the phone was on silent. The initiative, launched by Union Home Minister Amit Shah and Communications Minister Jyotiraditya Scindia, emphasizes the government's commitment to enhancing national safety infrastructure. Future tests will continue to refine this vital system, aiming to provide timely warnings that could save lives during actual emergencies.
