To fully operate post-shutdown, devices need more than just 4G. VoLTE (HD calling) is also necessary to continue making and receiving calls after 3G services are switched off.

If you have received a communication from us regarding the closure of 3G, it is likely that there is a device on your account that will be impacted by the network transition.

To avoid any impact from the 3G closure, active devices will need to have 4G or 5G for data capability and VoLTE (otherwise known as HD calling or 4G voice) to continue making voice calls.

To find out whether a mobile device is 3G, 4G Non-VoLTE, 4G VoLTE or 5G, you can read our FAQ.
