All mobile phone networks in Australia can now send emergency text alerts to mobile phone users near an emergency.
Previously, emergency text alerts could be sent only to a mobile phone's registered service address. It means visitors to the area didn't receive these warning text messages.
Optus network and Vodafone Hutchison Australia network will join Telstra, which was thus far the only network able to send emergency text messages.
The change aims at reaching all active mobile phone users, including those roaming on various Australian mobile phone networks.
