Thailand to launch new disaster warning system in July 2025

Thai authorities are preparing to launch a new “cell broadcast” warning system to replace traditional SMS alerts. The system is expected to be operational by July 2025 and aims to improve speed, range and reliability in the event of earthquakes and other disasters.

The new system is currently being tested by the disaster management authority in collaboration with National Broadcasting and Telecommunications Commission (NBTC). Messages will be able to be sent directly to all mobile phones within a specific geographical area, without users needing to be registered or have mobile data activated.

What is “cell broadcast”?

Cell broadcast is a technology that allows authorities to send warnings to all mobile phones in a certain area simultaneously, regardless of operator.

The technology works even when mobile networks are congested, making it especially important in times of crisis when calls, apps and social media often interfere with traditional warning systems. It is already used in countries such as Japan, the US and South Korea, and is considered more reliable than SMS in emergency situations because it does not overload the mobile network.

Briefly about cell broadcast:

• The technology was originally developed in GSM networks and also works in 3G, 4G and 5G.
• The alert is sent as a separate message and often appears as a notification at the top of the screen.
• Does not require internet connection, SIM registration or having a specific app.
• Messages can be prioritized and sent with different alert levels, e.g. for earthquakes, tsunamis or terrorist threats.
• Can be sent in multiple languages ​​simultaneously depending on the recipient's settings.

The NBTC has confirmed that Thai mobile operators such as AIS, True and Dtac have already participated in testing and received technical guidelines for implementation.

Background: The earthquake as a wake-up call

The decision to speed up the implementation of the new warning system came after the powerful earthquake in late March 2025, when several regions were hit by aftershocks and building damage. Many received SMS warnings late or not at all, which created concern and criticism of the existing systems: The SMS warnings for the 2025 earthquake – what went wrong?

The hope now is that "cell broadcast" will contribute to faster warnings, higher accuracy and save lives in future crises.
