VoLTE stands for Voice Over LTE (Long-Term-Evolution). LTE is another name for 4G. Most providers refer to VoLTE as HD Calling.

If your network provider offers VoLTE, then you won’t need to pay any extra to use it. Keep in mind, however, that not every phone and not every service will be compatible with the service.

VoLTE FAQs

VoLTE has resurged as a hot topic in Australia. It refers to a phone or other device’s ability to make calls over 4G networks – now crucial feature thanks to the impending shut down of the nation’s 3G networks.

Almost all 4G-capable mobile phones in Australia support VoLTE, but not all. It's no longer certain when the unlucky few will be cut off, thanks to the Optus and Telstra 3G network shutdown possibly being delayed due to concerns about emergency call support, but it will eventually happen. Vodafone finished shutting down its 3G network in January this year.

What is VoLTE?

The types of 4G we use in Australia fall under the category of 'Long-Term-Evolution' (LTE). The technical term for making calls over LTE networks is 'Voice over LTE' (VoLTE).

Once billed as ‘HD calling’, VoLTE is now the standard technology for mobile phone calls, and it will be the most basic option possible once the nation's 3G networks shut down.

As you might guess from the name, HD calling allows better-quality audio. The higher data rate of 4G also means VoLTE can make your phone calls sound clearer, thanks in part to a degree of background noise filtering.

Does my phone have VoLTE?

If your phone was released from 2019 onward, you can be reasonably confident it has VoLTE.

Even so, there are an estimated 740,000 (generally older) phones in Australia that work on 4G, but can't make emergency Triple Zero calls over VoLTE. There are also quite a few much 4G phone models that don't support VoLTE at all.

This could be a serious safety issue once Optus and Telstra shut down their 3G networks. The 3G shutdown dates are currently June 2024 for Telstra, and September 2024 for Optus, but these dates might be pushed back due to the aforementioned safety concerns. Vodafone had already finished shutting down its 3G network before the potential delays were proposed.

Here are some 4G phones that won't be able to make calls at all on the Telstra and Optus networks after the 3G shutdown:

Telstra VoLTE

Your Telstra calls are likely already using VoLTE whenever possible, no matter if you're on a prepaid or postpaid plan.

That said, Telstra didn't manage to shut down its 3G network before the Federal Government announced possible delays, and so not all the telco's calls operate over VoLTE just yet.

Vodafone VoLTE

All calls from prepaid and postpaid phone plans on the Vodafone Network use VoLTE. Given the telco finished shutting down its 3G network in early 2024, there's no option to fall back to 3G when VoLTE coverage is spotty.

VoLTE FAQs

VoLTE vs. WiFi calling

Where VoLTE makes calls over 4G, WiFi calling utilises a fixed broadband connection. WiFi calling can be useful in areas with poor mobile coverage or high congestion, but on your end, you shouldn't notice which is being used except for under rare circumstances.

Not all telcos in Australia support WiFi calling. Some smaller providers are missing this option.

Is VoLTE free?

You don’t pay extra to use VoLTE versus 3G calls. It's also a standard phone inclusion these days, so there's no cost added to a handset just because it has VoLTE.

Will my phone work with VoLTE?

Your phone probably already uses VoLTE for calls. If you're concerned the 3G network shutdowns will affect you, check out our guide about which 4G phones don't work with VoLTE.
