Optus 3G is no longer available. In order to connect to the Optus mobile network, you’ll need a device compatible with the 4G network 700 MHz and 4G VoLTE (which enables voice calls to be made over a 4G network).
The phones available for sale on our website have been tested to ensure they are compatible with the Optus network. If you have purchased or have been given a refurbished phone, second-hand phone, or a phone that was purchased overseas, check that it’s compatible using our Device Checker tool.
Important information about emergency calls to Triple Zero (000)
To keep you safe phones must support Triple Zero (000) calling over 4G (using VoLTE) in the event of an emergency. This is a legal requirement for all phones sold in Australia. Older 3G handsets, as well as some newer 4G/5G handsets (including those purchased overseas or from a retailer selling imported phones), do not meet these standards. From 28 October 2024, if you have a device that is not able to make Triple Zero (000) calls, Optus is legally required to stop these mobile phones from accessing the Optus mobile network. This means you will not be able to make or receive calls/texts or use data on the Optus mobile network from this date. Some devices may temporarily work on another provider’s network. However, the provider may also block the device if they determine that the devices cannot make 000 calls over 4G, as they are legally required to comply with safety standards.

From 28 October 2024, if you have a device that is not able to make Triple Zero (000) calls, under new law by the Australian Government, Optus is legally required to stop these mobile phones from accessing the mobile network. This means you will not be able to make or receive calls/texts (including emergency calls to Triple Zero ‘000’) or use data on the Optus mobile network from this date.
If your device doesn’t work with our 4G network or relies on 3G network for emergency calls, then it will no longer be supported.
To ensure you still have access, we strongly recommend you upgrade to a compatible device.
Check if your device is compatible using our Device Checker tool.
Note: Unless your call is for a legitimate emergency, DO NOT call Triple Zero (000) to test your device.
