Check my device before 3G closure

Our 3G network  will close from 31 August 2024. Before that happens, you'll need to ensure your device is compatible with the following technology and bands:

  • Required: 4G 700 MHz (B28) 
  • Optional: 4G 1800 MHz (B3) banding 

If you're unsure whether your device supports any of these bands, please check your device manual or manufacturers website.

Voice over LTE (VoLTE)

If your mobile device doesn’t have Voice over LTE (VoLTE) technology, even if it uses 4G, it will not be able to make voice calls on our network after 31 August 2024.

To continue using our network, you’ll need to upgrade the device to a 4G/5G VoLTE capable and compatible device before 31 August 2024. Doing so will ensure you can access Telstra’s network and will have both data access and voice calling compatibility.

Find out more about VoLTE, including what it is, what devices are compatible, and how to check or enable VoLTE on your phone.

Emergency Calling

Your mobile device must support VoLTE emergency calling to make an emergency call to 000 on our network, after our 3G network closes from 31 August 2024. If your device does not support VoLTE emergency calling, you will not be able to make an emergency call to 000 on the Telstra Mobile Network.
