3G Network change

Important changes are coming to our 3g network.

From September 2024, our 3G network is being repurposed to better support our growing 4G and 5G networks.

What is changing?

Our mobile network is powered by Optus, who are repurposing the 3G network to boost the speed, capacity, and reliability of their 4G network, as well as providing additional 5G capacity to more Australians.

If you would like to speak to someone about the change, get in touch with our friendly team.

Device Compatibility

check your device.

To check if your device will be affected, we recommend you refer to your device manual or contact the manufacturer via their website or by giving them a call.

In technical terms, you're looking to confirm:


If your device is reliant on 3G 900MHz spectrum for voice and/or data service.


If your device supports 4G VoLTE (including VoLTE Emergency calling).

If you're using your device to make and receive voice calls, then your device needs to support 4G VoLTE and have VoLTE enabled in your device settings from September 2024.


If your device is compatible with 4G 700 MHz (B28) spectrum.

L700MHz is low band 4G spectrum used by Optus and some other providers for optimal 4G coverage.

Even recent device models that may have been purchased from other retailers or overseas may not be compatible with 4G 700MHz spectrum band and therefore, may also be impacted.

The top 25 most common devices.

What's next?

What should I do if impacted by the network change?

Supports 4G VoLTE (if your device is used for voice calls)

Check with your retailer before purchasing a new device to ensure it supports these features.
