Singapore to roll out mass emergency alerts to mobile phones from May

From May, a mass emergency alert system will notify people via their mobile phones. SG Alert bypasses silent-mode settings and heavy network traffic, delivering alerts in any of Singapore's four main languages. It will tell people what's happening on the ground and advise them on next steps. Singtel customers will be the first to get the test alerts before it is progressively rolled out to users of other mobile operators. Noah Kong reports.
