Commencement of the 3G network shutdown

From 15 December 2023 Telstra, Optus and Vodafone/TPG will begin to shut down their 3G networks. The shutdown will begin with TPG/Vodafone network on 15 December 2023, Telstra on 30 June 2024 and Optus in September 2024. This is due to the 4G and 5G networks being widespread and in common use.

The shutdown means that devices that rely solely on the 3G network and do not have the capability to connect via 4G or 5G will no longer have connectivity, including the ability to make calls to 000.

The 3G network shutdown will typically impact older mobile handsets but could also impact other devices that connect over a mobile network such as baby monitors, medical alarms or EFTPOS machines.

If consumers have a device that relies on the 3G network, it’s important to upgrade these devices now to avoid being without service.

The Telecommunications Industry Ombudsman may be able to help with problems related to the shutdown, including:

  • Detriment that has occurred because of not being notified of the 3G network closure.
  • Contractual disputes
  • Paying for a service that cannot be used.

The TIO will not be able to handle complaints about having no coverage as a result of the shutdown, requests for the 3G network to stay connected, or handsets and devices that are no longer working and were not supplied as part of a current contract.

Consumers should always contact their provider first to try and resolve the problem. If you can’t work it out together, contact us on 1800 062 058 or make a complaint online at
