How do I enable VoLTE (Voice over LTE) on my mobile phone?

What is VoLTE?

Voice over LTE (VoLTE) lets you make clearer phone calls over any 4G (LTE) network. Your mobile phone will use VoLTE to make and receive these calls in countries where 4G is available. Mobile network operators around the world are beginning to shut down their 3G networks, meaning VoLTE will be required to make or receive phone calls (including emergency calls) when using their network abroad.

Emergency calling

Your mobile device must support VoLTE emergency calling to make an emergency call to 000 on our network, after our 3G network closes from 30 June 2024.  If your device does not support VoLTE emergency calling, you will not be able to make an emergency call to 000 on the Telstra Mobile Network.

Which devices are compatible?

To use VoLTE, you'll need a 4G device which is VoLTE-capable. It will also need to be compatible with the following technology and bands:

  • Required: 4G 700 MHz (B28), 
  • Optional: 4G 1800 MHz (B3) banding 

The devices listed below purchased from Telstra can make and receive VoLTE phone calls. You'll just need VoLTE enabled on your device.

All 4G and 5G phones and wearables launched by Telstra since January 2019 support VoLTE out of the box.

The list of Telstra 4G phones and wearables launched before January 2019 that support VoLTE is as follows:

  • Apple iPhone 6 and Apple Watch 3 onwards (with iOS 10 or later)
  • Samsung Galaxy S series 7 onwards, Galaxy Note 5 series onwards, all Samsung Galaxy Watch series
  • All Google Pixel phones
  • Boost Dex
  • Boost Jett

  • HTC U11
  • LG G5
  • LG G6

If you didn't buy your device from Telstra, you'll need to get technical assistance to see if you can enable VoLTE on your compatible device.

VoLTE International Roaming

Voice over LTE (VoLTE) lets you make phone calls on a 4G (LTE) network.

We have arrangements for carrying voice calls with each of our individual roaming partners in other countries. Traditionally our partners have provided 2G and 3G networks for carrying our roaming voice calls but Telstra is also making arrangements with a growing number of partners which can allow VoLTE on 4G to be used for these calls. In some countries VoLTE on 4G is the only option as our partners have already shut down their 2G and 3G networks.

This means VoLTE will increasingly be required to make or receive phone calls (including emergency calls) when roaming abroad. So it’s important to have a 4G or 5G phone that is compatible with our 4G VoLTE roaming arrangements to help ensure you can make calls when travelling. To use VoLTE when using your phone abroad in eligible countries requires the device to have VoLTE roaming capability. Not all VoLTE handsets have this capability. The handsets that can be used for roaming using VoLTE can be different to devices that can be used for VoLTE calling in Australia. The devices below are VoLTE International Roaming tested and capable devices that Telstra has launched prior to 1 July 2022. In addition, every handset/tablet that Telstra have launched since 1 July 2022 that supports VoLTE also supports VoLTE International Roaming. For any further information, please refer to our Technical Assistance.

Making emergency calls while overseas

In order to make an emergency call while overseas, it is important that your device also supports VoLTE Emergency Calls. If your device doesn’t support VoLTE Emergency Calls, and there is no 3G network coverage available in your location in the country you’re using your device, you will not be able to make an emergency call, even though you may have 4G or 5G coverage. The devices below are VoLTE Emergency Call tested and capable devices that Telstra has launched prior to 1 July 2022. In addition, every handset/tablet that Telstra has launched since 1 July 2022 also supports VoLTE Emergency Calls.
