Since 2019, Australia’s mobile network operators have been preparing to switch off their 3G networks to boost the capacity, speed and reliability of their 4G and 5G networks.
Telstra’s 3G network will switch off on 31 August 2024.
Optus is planning to switch off its 3G network from 1 September 2024.
TPG Telecom/Vodafone has already switched off its 3G network.
