Australia’s 3G Network Shutdown: What It Means for Your Devices

In 2003, Australia launched its first high-speed mobile network: 3G. After 21 years, all major providers are phasing it out, impacting thousands of devices nationwide. Here’s everything you need to know about the shutdown, and how it might affect you.

Key Dates for the 3G Shutdown

Starting from October 28, Telstra and Optus will begin turning off their 3G networks. Telstra expects to complete the shutdown within a week, while Optus plans to wrap up over the coming months. Vodafone was the first to cut 3G services, concluding its shutdown between December 2023 and January 2024.

Who Will Be Most Affected?

While most Australians use 4G or 5G networks, those in remote areas relying on “fortuitous” 3G coverage may face the most challenges. Unlike 4G, 3G signals cover greater distances, so some areas currently relying on 3G may experience coverage gaps. As Telstra strives to extend 4G reach, users outside their 3G service map might have limited options, which may include satellite services or costly upgrades.

How to Check if Your Phone Will Be Affected

If you’re unsure about your phone’s compatibility, check its connection type:

SMS “3” to 3498 for an easy compatibility check.
Alternatively, input your phone’s 15-digit IMEI number into the Australian Mobile Telecommunications Association (AMTA) tracker.

Devices Likely to Lose Connectivity

Phones and other devices manufactured before 2019 may lose functionality with the 3G shutdown, especially older models like the iPhone 4, iPhone 5, Google Pixel 2 XL, and Samsung Galaxy S5. Additional devices include:

Mobile phone boosters
Medical devices (e.g., fall alarms, cardio monitors)
Smart watches
EFTPOS terminals
Security cameras
Farm machinery

Some newer devices purchased overseas, or “grey phones,” may also be affected, particularly if they don’t support Australia’s Band 28 (700MHz) for 4G.

What Steps Should You Take?

For affected users, upgrading to a 4G or 5G-compatible device will be essential. Ensure your new device is configured for VoLTE (Voice over LTE) to continue making emergency calls over 4G. Your telco can help you find suitable options to keep you connected.

Why Is the 3G Network Being Retired?

The shift away from 3G reflects an industry-wide focus on advancing 4G and 5G networks to support faster speeds, better reliability, and greater capacity. Many countries, including the US and China, have already phased out their 3G services to prioritize next-generation technology.
