Things to know about VoLTE and VoLTE Roaming
In this article
What is VoLTE?
VoLTE stands for Voice over Long Term Evolution (LTE) which is another name for 4G. VoLTE allows you to make high-definition (HD) calls from a mobile using our 4G network.
Simply put, when you make a voice call over VoLTE, it connects faster and you can enjoy a clearer connection with reduced background noise.
Please note this service does have some limitations in poor coverage areas or in areas where you might move from 4G to 3G often due to the terrain or other coverage factors.
How will I know if I have a compatible phone?
If you see VoLTE next to the signal bar at the top of your phone, then your device is VoLTE capable, and VoLTE is turned on.
Check out our list of VoLTE compatible devices.
Service icons
Android icons: you should see a VoLTE icon in the top right hand corner if VoLTE is enabled.
iPhone icons: Don’t worry if there’s no icon. Even if VoLTE is turned on there is no icon. You’ll need to check your settings to ensure that VoLTE is enabled.
How do I check or change my settings?
If you have checked your device is capable using the supported device list and your phone has been updated, you can check VoLTE is switched on in your settings.

If the VoLTE option is not available when you go to your network settings your device likely will not support VoLTE.
Note: For Samsung, Oppo and other models dual SIM instructions should be the same as above.
What happens if I don’t switch to a VoLTE capable phone?
You’ll need to upgrade to a VoLTE capable device if you want to stay connected after the 3G shutdown.
We offer a range of 4G and 5G ready phones in 2degrees stores. To upgrade to a new phone, jump online, or head into your nearest 2degrees store.
Can I use my phone overseas?
Mobile operators in some countries like the USA and Australia, are either starting to or have already shutdown their 3G networks.
From 28 October 2024, all 3G networks in Australia are due to shutdown. Without an up-to-date phone, you won't be able to use voice services while roaming. To avoid any issues, check your phone is VoLTE roaming capable before your trip.

Can I make an emergency 111 call with VoLTE?
Yes, emergency calling on a VoLTE capable device is supported when you’re in an area with coverage. Unfortunately, if your phone isn’t VoLTE capable, and if you're in an area that doesn't have 3G coverage, then you won't be able to make voice calls including to emergency services.
Because of this it is important you upgrade to a VoLTE capable device before we shutdown the 3G network.
