First thing’s first: what’s VoLTE?
VoLTE (Voice over LTE) is a feature that lets you make clearer phone calls over the 4G (also known as LTE) network, where it's available.
VoLTE is kind of like an add-on to 4G technology. Some phones have it (either built-in, or as a feature you can enable), and others don’t. Phones that don’t have VoLTE rely on the 3G network for calls.
When the 3G network closes, you’ll need VoLTE for calls
When Telstra closes its 3G network on 31 August 2024, phones that don’t have VoLTE – as well as 4G phones that don’t have VoLTE switched on – won’t be able to make phone calls. We’ll get in touch with customers who have these phones and let them know what they need to do.
How do I start using VoLTE?
There are two things you need to do to start using VoLTE:
Make sure your phone’s operating system is at least iOS 10 or Android 9. If it’s not, you’ll need to update it (in some cases, this will enable VoLTE automatically).
Turn on VoLTE in your phone’s settings. When you turn on VoLTE, your phone will automatically use 4G for texts and data too (where it’s available).

How do I know if my phone has VoLTE?
Most phones released in Australia after January 2019 should have VoLTE – either built in, or as a feature you can enable.
Below is a list of 4G/5G phones that you can use with a Belong SIM. That means:
they have VoLTE
they have VoLTE Emergency Calling, and
they support B28/700MHz
This is the main 4G frequency on the Telstra network. Phones that can’t connect to this frequency may have patchy or limited service when using a Belong SIM.
Although this is a pretty robust list, we can’t guarantee compatibility – specs sometimes change from one device to the next, which can affect network requirements and VoLTE functionality.

This list refers to phones released in Australia. Phones from overseas (even if they’re bought from Australian stores) are sometimes configured for overseas markets, which can make them incompatible with our network.
Software updates can also affect whether a device supports VoLTE.
If your device isn’t listed here (or if your device was bought overseas), check the manual or manufacturer’s website to see if the device fits the compatibility requirements listed above.
