As the 3G switch-off nears, beware of being left to your own devices in an emergency

Only a few days remain before Telstra and Optus officially switch off their 3G networks at midnight on Sunday night (27 October).

The two major Australian mobile phone network providers are the last operators in the country to offer the service but are discontinuing the connection to boost the capacity, speed and reliability of their 4G and 5G networks.

Rural and regional communities make up the great majority of people who still use the 3G networks and are being encouraged to switch to a 4G or greater-capable device before the end of the week.

Telstra has said that some 4G devices, particularly those bought overseas, may still struggle with Australia’s 4G network as they rely on older hardware, but has provided a tool to check whether mobile devices will need to be upgraded to use 4G and 5G networks.

By texting “3” to 3498, Telstra will respond to clarify whether your device will need to be upgraded.

Other ways to check include through the network settings of your device, making sure that 3G is not the only option and that there are choices for ”VoLTE” capabilities.

Federal Member for Riverina Michael McCormack has weighed in on the big networks’ decision to discontinue the 3G service and the concerning circumstances in which some regional residents can find themselves.

“Alarmingly, there are some mobile phones which will continue to be able to make ordinary calls after the switch-off but will not be able to make emergency calls as they use the 3G network for such calls,” Mr McCormack said.

“It is imperative to confirm your phone does not fall into this category, which could take you by surprise and cause significant issues in an emergency.

“The 3G network switch-off has been a long time coming, but in less than five days it will have finally occurred.”

Mr McCormack said now was the time to ensure your device would continue functioning after the closure.

“People are advised to text “3” to 3498 to receive an automated reply informing you whether your device will work as normal after the switch off.

“Smartwatches, tablets, EFTPOS terminals, personal emergency alarms and other devices may also be affected by the switch-off.

“I encourage the public to visit www.3gclosure.com.au for further information and, if necessary, to confirm your device will continue to operate with its manufacturer.”
