SG Alert is the new mass emergency alert system being launched by the Singapore Civil Defence Force (SCDF).
For any major emergencies, like fires, chemical incidents or spills, and terrorist attacks, Singaporeans will get an alert sent to their mobile phone. The alert will contain key information on the incident at hand, including a brief description and the locations affected. It’ll also contain instructions on how citizens can protect themselves.
The first public test will take place on the 10th of May, with those on the Singtel network receiving test messages. This includes MVNOs, so expect a message if you’re with GOMO, VIVIFI, Zero1, or ZYM Mobile. The rollout will reach Singtel customers first, with StarHub users to get access by the end of 2026. Finally, M1 and SIMBA users will gain access in mid-2027. This also applies to those who have a phone plan with an MVNO. If you’re with a StarHub MVNO, for example, you’ll gain access by the end of the year.
When fully implemented, everyone in the affected area will receive the alert. This extends to foreign visitors and tourists using mobile phones connected to Singapore mobile networks. As long as their mobile phones are updated to the latest operating system, they will receive the alert.
For iPhones, this means running on iOS 26.4 or later, and for Androids, running on OS 12 or later. Phones running the Google Play system should be updated from the 1st of February onwards.
The system uses cell broadcast technology to allow messages to be delivered via local mobile networks without requiring users to download an app or hand over their personal information. The alerts operate independently of mobile data services too, so they can bypass high network traffic or congestion, as well as silent mode settings like Do Not Disturb.
Other devices like smartwatches and tablets with cellular connectivity may also receive SG Alerts. SCDF has said it’ll complement the existing emergency systems, like SGSecure, which is used for terrorism threats and MyResponder, which is used for fire and medical incidents. They’ve also said the system will boost their capacity to respond to emergencies promptly and give the public ample time to respond.
"In emergencies, prompt and timely communication with the public is critical," said Senior Assistant Commissioner Alan Chow, senior director of SCDF's operations department.
