Thailand, criticised over Bangkok building collapse, to test mobile alerts
The system will use three mobile networks to send warning messages in Thai and English, accompanied by a siren

Director General of the Department of Disaster Prevention and Mitigation (DDPM) Phasakorn Boonyalak said the Cell Broadcast System (CBS) will undergo a test run next month in localised areas including the sprawling capital, which was badly shaken by the 7.7-magnitude quake in neighbouring Myanmar.
The system will use three mobile networks to send warning messages “quickly and with wide coverage, both on natural disaster and security threats”, he told a news conference.
Starting on May 2 with the smallest target area – four city hall buildings – there will be three test runs, with the third and largest drill covering the whole of Bangkok and Chiang Mai provinces on May 13.
Residents’ cellphones will get a pop-up message on their screens in Thai and English, accompanied by a siren, Phasakorn said.
