Telstra and Optus have extended the closure of their 3G networks to October 28 instead of the end of this month, allowing more time for customers to prepare.

All 3G users with 3G reliant devices need to be ready to move to 4G and 5G networks by October 28, 2024, as the 3G networks will commence closure from that date.

Over the coming weeks, Telstra and Optus will invest in a public safety campaign to ensure anyone who still depends on the 3G network for connectivity – for mobile and data – is aware of the actions they need to take to stay connected ahead of the closure of each network.

It is critical customers check their devices are compatible with the 4G or 5G network particularly to ensure they are still able to call emergency services and act upon any communications they receive from their service provider.

It is also important for users of connected devices like medical monitors, IoT sensors and EFTPOS to check whether they rely on the 3G network by contacting the manufacturer or supplier.

According to the providers, closing 3G is necessary to free up spectrum for the 4G and 5G networks so faster, more secure, and more reliable mobile services that Aussies need and expect can be provided.

According to the federal minister’s office the mobile industry working group - set up by the federal government in March this year – is continuing to address concerns about the risk to public safety, while improving efforts to identify and contact customers with impacted handsets and make information available on the impacts of the switchover.

The government continues to encourage all Australians to check if their mobile device will be impacted by the switchover by texting ‘3’ to ‘3498’ or by visiting: www.3gclosure.com.au
