The estimated number of 4G mobile handsets that could lose access to Triple Zero after the 3G switchover has decreased from 740,000 in March 2024 to 102,000 as industry measures ramp up.
Mobile customers of Telstra, Optus and TPG/Vodafone networks can all text '3' to '3498' and receive an instant reply on whether their mobile handset could be impacted by the 3G switchover, with TPG/Vodafone recently enabling this SMS checking capability across their network.
Additionally, Optus customers who may be affected will receive a recorded message when they make a first voice call each day together with a proactive SMS reminder of the need to take further action.
The latest industry figures come as the Albanese Government and industry continue to work closely to ensure customers who may be impacted are identified and informed ahead of the switchover.
TPG/Vodafone closed its 3G network on 30 January 2024. Telstra and Optus plan to switchover fully to 4G and 5G from 1 September 2024.
First announced in 2019, the switchover will provide more efficient use of spectrum by mobile operators to boost capacity and data speeds.
However, a subset of 4G handsets configured by the manufacturer to rely on 3G for Triple Zero access. This may include devices that are older, purchased overseas, or second-hand.
Communications Minister Michelle Rowland set up a Working Group with industry in March, after it was revealed that approximately 740,000 handsets could be affected.
Through the Working Group, industry has undertaken significant efforts to identify and contact customers with these handsets and make information available and to guide consumer actions. Industry is also providing financial hardship measures to customers to support the switchover.
The Australian Mobile Telecommunications Association (AMTA) has also established a tool that allows consumers to enter their device's unique 15-digit IMEI number to see if they are impacted. This new tool, and important information about the 3G switchover, is available at www.3gclosure.com.au
