The 3G shutdown, which has been in the works since 2019, is being carried out to enhance the capacity, speed, and reliability of newer 4G and 5G networks.
Vodafone, Australia’s third major carrier, already shut down its 3G service earlier this year.

Telstra announced that devices that rely solely on 3G—whether for general connectivity or emergency calls—would be blocked to comply with new federal regulations. Telstra’s 3G shutdown will proceed in phases, starting with Tasmania and finishing across the mainland by November 4.
Optus said it has sent notifications to millions of customers, including discounted and zero-cost device options for those needing an upgrade due to the cost-of-living pressures.
Devices affected by the shutdown include those reliant on 3G, certain 4G models that use 3G for emergency calls, and international devices incompatible with Australian 4G technology.
The 3G shutdown is expected to not only affect older cell phones, but also other devices including those in cars, tablets, security cameras and medical alarms. Despite years of warnings from telecom providers, it is estimated that thousands of Australians have yet to upgrade to newer technology, leaving them at risk of being disconnected.
To check if a device is impacted, customers of any Australian provider can text “3” to 3498.
