BANGKOK, THAILAND – At exactly 2 p.m. on Monday, January 20, smartphones across Thailand sounded an eight-second alarm as authorities tested a new nationwide disaster warning system.
Nationwide alarm on January 20
The Department of Disaster Prevention and Mitigation (DDPM) conducted a nationwide test of its new cell-broadcast alert system, sending a message to all 76 provinces and Bangkok. The alarm was heard for about eight seconds and sounded even when phones were muted, locked or set to vibrate. The test message on screens stated: “This is a test message from Department of Disaster Prevention and Mitigation (DDPM), not real situation. No action required.”
How the new warning system worked
The system was a joint project between the DDPM, the National Broadcasting and Telecommunications Commission (NBTC) and all mobile network operators. It was designed to warn the public rapidly in real emergencies, including floods, security incidents and dangerous PM2.5 air pollution.
“This test is crucial in order to be able to save lives in the event of a disaster.”
said Teerapat Kachamat, DDPM director-general.
Technical requirements for receiving the alert
Not every phone received the alarm, as devices had to support cell broadcast technology. The minimum requirement was iOS version 18 or Android version 11, meaning older handsets did not get the warning. Authorities advised users to check for software updates, noting that the system had already been tested successfully on a smaller scale in 2025.
Why the test mattered for disaster readiness
Thailand had been increasingly affected by natural disasters, while traditional warnings via radio or social media often arrived too late. The cell-broadcast alarm overrode other phone functions and was described as the fastest and most direct way to warn millions of people at once.
“In an emergency, every second counts,”
said a DDPM spokesperson, adding that the drill was meant to ensure the technology worked smoothly nationwide.
Officials urged calm during the drill
Authorities appealed to the public to remain calm, stressing that the exercise was only a test. People were told they did not need to take any action and should not call the police, and the test message contained no links. After eight seconds, the alert disappeared automatically, with officials asking residents simply to remember the time and date of the drill.
Building a safer and more resilient Thailand
In the long term, the system was intended to make Thailand safer and more resilient to future crises. Officials described it as a step in the right direction and an important element of modern disaster management. The successful rollout could serve as a model for other countries in the region, as Thailand prepared for future challenges by rehearsing a worst-case scenario without any real danger.
