3G Network Switch Off

Australia’s mobile network operators are switching off their 3G networks.

The switch-off may mean you cannot call Triple Zero (000) in an emergency. If you own a 3G or an older 4G device, you should contact your provider now to find out what to do.

It is very important that you do not call Triple Zero to test your device. This won’t help you work out if your device is affected and may stop others accessing life-saving support.

It’s important that you do not test your device by making an emergency call.

Optus is planning to switch off its 4G network from 1 September 2024.

Telstra is planning to switch off its 4G network from 31 August 2024.

Vodaphone has already switched off its 3G network.

3G devices

If you use a 3G mobile device, once your provider’s network is switched off, you will not be able to make or receive phone calls or text messages. Once all 3G networks are switched off, you will not be able to call Triple Zero.

4G devices

Some 4G devices may be unable to make any voice calls once a 3G network is switched off, including calls to Triple Zero.

Some 4G devices may continue to work for voice calls and data but will not be able to make calls to Triple Zero. Most at risk are older 4G devices and devices that were purchased overseas. Contact your provider now to check.

To ensure your mobile fleet still has access to essential services such as the internet and Triple Zero, we strongly recommend you upgrade your mobile devices as soon as possible.

We recommend you upgrade to a device that supports:

  • The 4G Network 700 MHz (LTE Band 28 or also known as the B28 spectrum)
  • 4G Voice over LTE (VoLTE), which is the technology that enables voice calls to be made over a 4G network, including emergency calling.
  • You may need to enable VoLTE in the device settings
  • Some recent 4G devices may also be impacted including models that were purchased overseas or imported and aren’t configured for Australian networks or do not support 4G VoLTE.
