The ‘Cell Broadcast Alert System’is developed with the support of the National Disaster Management Authority (NDMA)

During the test, mobile users across the country received 'emergency alert messages' accompanied by a beep sound on their devices

The initiative is seen as a significant step towards ensuring swift and effective dissemination of information during natural disasters, severe weather events and other emergency situations

The system is currently undergoing pan-India testing in the form of flash SMS messages issued by the NDMA

“NDMA will test Cell Broadcast Alerts on May 2, 2026, in your area. On receiving the message on your mobile phone, no action is required. Please do not panic,” the government said in a sample message

Locals in Mumbai noted that the alerts were delivered with a loud alarm tone and a flashing message on mobile phones

The NDMA is the apex body for disaster management in India
