The 3G network has officially been shut down across Australia by all major mobile providers—Telstra, Optus, and Vodafone. From now on, all mobile connections will be using 4G or 5G networks.
What does this mean for you?
- Some devices may have been affected, including mobile phones, tablets, medical devices, security cameras, and more.
- While 4G upgrades are still ongoing, you may experience some instability during this transition.
If you’re facing issues with your mobile connection, the most important step is to contact your Retail Service Provider (RSP) immediately. They can identify whether the issue is related to the 3G shutdown or other factors.
For Telstra customers, a 3G Helpline is available to assist you:
Telstra 3G Helpline: 1800 990 853
Hours: 8am to 7pm Monday to Friday AEDT
Stay connected and let your provider know about any issues you’re experiencing.
