With just days left until Telstra and Optus pull the plug on their 3G networks on 28 October, the Australian Mobile Telecommunications Association (AMTA) is urging Australians to check their devices to ensure they're prepared for the shift.

The 3G network, which has been a reliable technology for years, is making way for the superior performance of 4G and 5G networks, which offer faster speeds and more reliable connectivity.

The upcoming shutdown is part of a broader move toward more advanced mobile technology.

Vodafone, owned by TPG Telecom, already closed its 3G network earlier this year, leaving Telstra and Optus to follow suit this month.

This marks the end of an era for 3G, with all mobile traffic now set to transition to 4G and 5G.

While many users have already made the switch to newer devices, there are still around 60,000 devices across Australia that rely on 3G and will be affected by the shutdown.

Communications Minister Michelle Rowland recently warned that these devices will no longer be able to make calls, including emergency calls to Triple Zero, after October 28th.

Though this number has improved from initial estimates, it's still a concern that needs immediate attention.

What devices will be affected?

Mobile phones are not the only technology impacted by the 3G closure.

A range of interconnected devices, such as EFTPOS terminals, security systems, medical monitors, GPS systems in vehicles and tractors, and soil monitors in farms, are also reliant on the 3G network.

These essential tools might stop functioning correctly if they aren’t compatible with 4G or 5G networks, leaving users vulnerable to disruptions.

Carol Bennett, CEO of the Australian Communications Consumer Action Network (ACCAN), stresses the importance of checking all devices, not just mobile phones. "It is simple to ensure your mobile phone will work after the shutdown," she says.

How to check your devices

If you're uncertain whether your phone or other equipment will work post-shutdown, there are a few simple ways to check:

• • Text ‘3’ to 3498: This service is available on any Australian mobile network and will give you an instant answer regarding your phone’s compatibility after 3G is switched off.

• • Visit AMTA’s ‘Check My Device’ website: The website allows you to check your phone’s make and model to see if it’s supported on 4G or 5G networks. The site is accessible in 11 languages, ensuring everyone has the opportunity to stay connected.

• • Contact your service provider: Your mobile carrier can help you find an upgrade solution suited to your needs if your device won’t work after the 3G shutdown.

Final call for action

Despite extensive campaigns by telcos, government bodies, and consumer advocacy groups, some Australians may still be unaware of the impending changes.

If you, a family member, or a friend rely on 3G for mobile or other services, now is the time to act.

This shift may require some adjustments, but it also brings opportunities for better connectivity and faster service.

For many rural and regional Australians, upgrading to 4G or 5G will mean more reliable service, greater access to digital tools, and a more future-proof connection to the rest of the world.

As the countdown to 28 October continues, Ms Bennett reminds Australians "All Australians must take this final opportunity to check their devices to ensure they remain connected and safe."
