How do I enable VoLTE on my mobile phone?

Voice over LTE (VoLTE) lets you make clearer phone calls over 4G (LTE) networks. Mobile network operators around the world are beginning to shut down their 3G networks, meaning VoLTE will be increasingly required to make or receive phone calls (including emergency calls) when using their networks abroad.
 

Emergency calling

Your mobile device must support VoLTE emergency calling to make an emergency call to 000 on our network. 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.

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.

VoLTE compatible phones and wearables sold by Telstra after January 2019 do not need any action.

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.

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.

International roaming is not available in all countries and destinations are subject to change. If the destination you’re travelling to is not listed in the Pay-as-you-go rates, it means you can't use your Telstra service to roam there. 

In the listed destinations voice calls, SMS, MMS, and data services may not be available with all operators. The availability of voice calls, SMS, MMS, and data services are dependent on a number of factors including your destination, the participating operator in that destination and the device you use.
 

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.
