Australia’s leading telecom companies, Telstra and Optus, have postponed the closure of their 3G networks by two months. Originally scheduled for the end of August and throughout September, the shutdown will now occur on October 28. This delay is aimed at giving customers more time to prepare and understand the impact of the switch-off.
The decision comes after concerns were raised about the potential disruption to thousands of devices, including older handsets, EFTPOS machines, and medical alert systems, that rely on the 3G network.
A Senate inquiry revealed that over 77,000 handsets were still in use as of early August, many of which may lose the ability to make emergency Triple Zero calls.

Additionally, certain 4G phones, particularly those purchased overseas or second-hand, may default to 3G for emergency calls due to lacking Voice over LTE (VoLTE) technology.
Users are encouraged to check their devices by texting “3” to 3498 or visiting the Australian Mobile Telecommunications Association’s website for further guidance.
What You Should Do to Prepare
Communications Minister Michelle Rowland urges all Australians to verify whether their devices will be affected. The delay provides a crucial window for customers and businesses to take action and ensure they remain connected and safe after the 3G networks are decommissioned.
