The Cell Broadcast Service (CBS) — the system built to flash urgent warnings to people during disasters and emergencies — has been put on hold across the country for the time being. The move comes on the instruction of the National Disaster Management Authority (NDMA). In plain terms, it means that for a while, the special emergency alerts that used to appear on mobile phones through this system will no longer reach users.
NDMA Writes to Every State
According to the Kerala State Disaster Management Authority (KSDMA), the NDMA has sent a letter to all states asking them to halt the Cell Broadcast System until further orders. What stands out is that no reason has been given so far for why the service was stopped. Officials have described it as a temporary step and say they expect the service to be restored before long.
So What Exactly Is the Cell Broadcast Service?
The Cell Broadcast Service is a specialised piece of technology. It allows a single warning message to be pushed to millions of mobile users within a particular area all at the same time. It is used to instantly alert people during floods, earthquakes, cyclones, heavy rain or any similar emergency situation.
The biggest strength of this system is that it does not depend on ordinary SMS or an internet connection. That is precisely why it can still deliver an alert even when the network is under heavy load. The warning shows up as a pop-up on the mobile screen, and on many phones it even arrives with a loud sound so that it is hard to miss.
Rolled Out Nationwide in May 2026
The Indian government launched this system across the country in May 2026. It was developed jointly by the Department of Telecommunications (DoT), the National Disaster Management Authority (NDMA), the Ministry of Home Affairs and C-DOT.
How Will Warnings Reach People Now?
With the service paused, the emergency alerts sent through this particular system will not come through for now. That does not, however, leave people in the dark. The government and local administrations will continue to issue essential information and warnings through other channels, just as before.
It is not yet clear how long the suspension will last. The service will be switched back on only once the NDMA makes its next announcement. Until then, people have been advised to rely on and keep an eye on the official information put out by the weather department and other government agencies.
