3G Network Closure

What's changing?

From 28th October 2024, our network partner Optus will repurpose 3G technology to boost the capacity, speed, and reliability of the 4G network and the growth of 5G technology. This standard practice is called “re-farming,” where a specific mobile radio frequency band is reused from one technology to another.

Important information about emergency calls to Triple Zero (000)

If your device is reliant on 3G for emergency calls, you won't be able to make an emergency call to Triple Zero (000) after the Optus 3G network shuts down from 28 October.

To ensure you still have access, we strongly recommend you upgrade your device as soon as possible if you have received an SMS, email, or letter from us.

You can confirm if your device is impacted by the Optus 3G Network Closure by sending ‘3’ to ‘3498’ via SMS* from your Commander mobile service or by checking your device IMEI Number at AMTA Check My Device.

*Note: If you have recently removed your SIM card or upgraded your handset, this text service response may not accurately represent your device’s 3G impact status.
