Revolutionizing Emergency Communications in Singapore

The Singapore Civil Defence Force (SCDF) announced on Friday, April 17, the upcoming launch of SG Alert, a state-of-the-art mass emergency notification system. Unlike traditional SMS notifications, SG Alert utilizes cell broadcast technology to deliver simultaneous messages to mobile devices within seconds. The system is engineered to function independently of mobile data, ensuring that critical warnings reach the public even during peak network congestion or major infrastructure disruptions.

Rollout Schedule and Network Compatibility

The implementation of SG Alert will follow a phased timeline across Singapore's major telecommunications providers:

Singtel Users: Rollout begins in May 2026, with an islandwide public test scheduled for May 10 at 12pm.

StarHub Users: Integration expected by the end of 2026.
