DDPM to conduct third cell broadcast test in Bangkok and 4 provinces on Tuesday at 1 PM, ahead of a planned nationwide alert system rollout.
The Department of Disaster Prevention and Mitigation (DDPM) will conduct its third cell broadcast (CB) system test on Tuesday, covering Bangkok and four other provinces.
The test is scheduled for 1 PM and will include Bangkok, Chiang Mai, Udon Thani, Ayutthaya, and Nakhon Si Thammarat in its coverage area.

The DDPM declared both previous trials successful.
Details of the Broadcast Alert Message
During the test, the CB system will issue an eight-second alert tone followed by a bilingual message in Thai and English, stating:
"This is a test message from the Department of Disaster Prevention and Mitigation (DDPM). No action required."
Nationwide Trial Planned Following Regional Tests
Following the completion of the three regional trials, the DDPM intends to carry out a nationwide test of the CB system in the near future.
Warning About Potential Scams
The DDPM emphasised that the official test message will not contain any links. Residents in the five provinces are urged to remain vigilant and not fall victim to call-centre scams that may send fraudulent SMS messages containing harmful links.
The agency also noted that test signals may spill over into areas adjacent to the five targeted provinces.
