only Apple seem to have had the spine to stop it from becoming a mess. All the others are still quite happy to trot out telco specific varients and softwares to help keep the telcos in the hardware game.

Nah its not telco specific to keep them in the game, it's due to OS size.... Apple works universally everywhere but its IOS is over 10GB

Androids are a fraction of that

VoLTE has clearly been driven by the telcos to get their skin back in the game for hardware sales again with how bad the provisioning of it is,

Ah, no. Source: am telco.

Don't get me started on 2d and VoLTE.....

Been a customer of theirs for 15+ years and they've generally been pretty great. I've now got a personal and business account with them, the business account was chosen primarily because of the included roaming to Australia (frequent-ish travel there for work). VoLTE over there simply doesn't work. Multiple SIMs, multiple phones, different accounts, no good. Been told twice so far that 'we've resolved it and it should now be working'. Only to arrive for my next trip to find out that it still isn't working. What makes it even more frustrating is that data and sms work, wifi calling works (in Aus) in North America, everything (including VoLTE) works!

I'm using a handset from them, on a plan that they advertise yet it doesn't work!? Each time I've rung the support line I've been told that other people are having the same issue, yet nothing seems to be fixed?! This is over the course of multiple months.

Not the telcos here, the big ones in US and Europe - they all get custom software with their bloat and spyware prebaked into them from the samsungs etc.

If they had wanted it, could have easily been provisionable to the phones instead of baked into the firmware, but that is not what they ended up with.

Yea I can't understand how there's not some standard way to detect VoLTE params (keep in mind I know little about how it works)

But the handset queries volte.local and the Mobile Carrier's DNS resolves that to an IP and the handset then queries http://volte.local/.well-known/volte-params.json

Why the details have to be baked into each ROM I don't understand (probably because this isn't my knowledge domain...)

I bought a AGM M6 for my daughter, I specifically emailed and asked before I bought it if it supported VoLTE/4G because of the shutdown, they told me yes it does. They even updated their website _after_ I asked them and it now says on there "4g and VoLTE enabled" - Checks have proven though it quite clearly is not. I've asked them for a remedy, either a firmware update (unlikely) or my money back.

I was over there for nearly 2 months between March and May. Worked perfectly for me.

You are on an iPhone, remember Aus IMEI block any phone not on their "approved" list

assume the traveler was on some sort of Android which is not on their list

Ah, well, there's nothing we (and by 'we' I mean 'any NZ carrier') can do about that.

@thewabbit your options are

Buy a cheap phone in Australia from 2degrees inbound roaming partner (I think this is Optus)
- Bear in mind it may not have the 2degrees VoLTE profiles so may be useless for VoLTE here
Upgrade to an iPhone which has all the VoLTE profiles for OneNZ/2Degrees/Spark in NZ and Telstra/Vodafone/Optus in Australia, and will give you hassle free roaming anywhere else in the world too.

Really?! Then is this not false advertising on your website?

I'd fully understand if I had a handset that I didn't purchase from 2D.....

It has crossed my mind to grab a cheap handset...

Maybe you could upgrade your current phone to an Android on this list with VoLTE roaming compatibility?

Whilst this is the official list. I can say a OnePlus 12 does roam quite nicely (this was December 2024 in Japan).

But please please please... if your phone is not on the list and it doesn't work, then there maybe not much help for you until you put your SIM in a supported handset.
