3G network switch off

Telstra and Optus will be switching off their 3G mobile networks in 2024. Vodafone has already switched off its 3G network. 

The switch off will impact 3G and some 4G devices. Your service provider should contact you if your device will be impacted. 

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.

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.

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.

Telstra is planning to switch off its 3G network from 31 August 2024.

The Australian Government is working with mobile network operators and the Australian Mobile Telecommunications Association (AMTA), which is the peak mobile telecommunications industry body, to support the planned switch offs in a safer way. 

You can also find information about the types of devices that may be impacted by the switch off on the AMTA website.
