Important: Triple Zero Impacted Devices 

It is a requirement that all mobile phones sold in Australia support Triple Zero (000) calling over 4G networks (Voice over LTE emergency calling). Older 3G handsets, as well as some 4G/5G handsets may not be compliant and are unsafe, as they may not be able to call emergency services, including Triple Zero (000). 

Telstra is legally required to prevent mobile phones that cannot call Triple Zero from accessing its network from 28 October 2024. Once a device is blocked, you will not be able to use that handset for voice or data.
