Optus is urging customers impacted by the shutdown of 3G to replace their device before the network is switched off from September 2024.  

The Optus 3G network will be switching off and repurposed to boost the capacity, speed, and reliability of our 4G network and rollout 5G to even more Australians.

Customers with impacted devices are being communicated directly to about this industry wide change which will impact the ability of some customers to make emergency calls.   

“We are assisting customers to stay connected during an industry wide switch off to the 3G network in Australia This is very important because this may impact the ability for some customers to make a call to emergency services,” an Optus spokesperson said.

“If you receive information from Optus telling you that your device is impacted, then it is critical you upgrade your device.  Please contact us to discuss your options.”  

The types of Optus devices impacted may not just be handsets but also data-only devices such as tablets and dongles.  

This will also include both customers who are still reliant on 3G only devices and those who may be using a 4G device that may also rely on the 3G network. In some circumstances, a device will be on the 4G network but uses 3G for emergency calls, this includes devices purchased overseas that aren’t compatible with Australian 4G technology.   

In a very small number of areas where 4G coverage is not yet available, we will not be shutting off 3G until a replacement 4G service is available.   

Customers can check if their device is impacted by texting ‘3’ to ‘3498’ (mobile devices only, please text from the device you are concerned about), calling 1300 219 070 or if you are a Prepaid customer call 1300 720 225 and visiting your local Optus retail outlet.

Optus is also providing additional support to vulnerable customers. For more information about the 3G Shutdown please go to – www.optus.com.au/3G.
