Govt Tests Cell Broadcast System Across India: Alerts Sent via Department of Telecommunications Network

Unlike standard text messages, cell broadcast alerts are sent simultaneously to all mobile phones in a specific geographical area. This ensures faster and wider coverage without overloading telecom networks. This makes it even more effective during major emergencies, when phone lines and data networks are often congested.

This technology has been integrated with the existing SMS system to strengthen alert delivery during natural disasters such as tsunamis, earthquakes, lightning strikes, and man-made emergencies such as gas leaks or chemical hazards.

This system is completely indigenous. C-DOT has been entrusted with the indigenous development and implementation of this cell broadcast-based alerting system.

As part of the nationwide rollout, testing and trials are being conducted to assess the system's performance and reliability before its formal inauguration. During this time, citizens may receive test messages in English, Hindi, and regional languages ​​on their mobile devices.

According to reports, officials have stated that since mobile towers from different networks are being evaluated, users may receive these alerts more than once. This is normal and expected. The government has clarified that anyone receiving these messages does not need to respond.

Test messages will only be received on mobile phones with 'Cell Broadcast Test Alerts' enabled. Users can manage these settings by going to: Settings > Safety and Emergency > Wireless Emergency Alerts > Test Alerts.

These messages are part of a planned nationwide testing exercise and require no action from receivers. Once the trial is completed and the system is officially launched, it will work automatically during real disasters, reaching citizens in the affected area within seconds.
