4G VoLTE calls confirmed working with carrier x

[lm2]

Hi Kevin. Thanks for your response. Obviously I am no telecommunications expert. Not even a beginner.

Yes, my previous claims were incorrect.
I have spoken again with Vodafone to clarify the issue for myself somewhat.
My understanding is still very bad,
but from what I understand (please correct me where needed):

4G internet / Data works on the LTE standard,
and obviously that is still operational with Vodafone and will remain so.

VoLTE enables voice data over internet.
If a phone does not have VoLTE enabled, or has no capability for VoLTE,
it will not be able to communicate voice data over the 4G network.
As such, my phone had previously been doing voice over 3G. 

Anyway,
I guess the crux of my question is whether Pinephones will support VoLTE either with only basic / minimal config to the modem (or whatever else)
to be compatible with either Vodafone and/or any other telco / provider within Australia (?)

makes me think this is possible with both Telstra, and TPG / Vodafone,
and I would like to know more, about ease of setup.
Is it just as described in this thread?

Vodafone can't provide me with any actual information,
they just want me to go on some rubbish plan for one of their handsets.
...no surprise there.

I have never actually purchased a brand new handset, and PinePhone (or possibly fairphone) are the only ones I would purchase new,
as Pinephone are the only manufacturer making privacy-conscious / privacy-respecting phones, and with Linux by default.

I use vodafone in oz (via iinet) and volte works fine using the latest adsp firmware and Biktorj's custom modem firmware (https://github.com/the-modem-distro/pine...LASHING.md) . I don't think volte worked with stock firmware tho.

Hi Kevin.
Ah! Living in zi good schnitzel-town! (:  
Thanks so much for the replies. 
They have been confidence-inspiring. 
I think based on what has been said already and previous confirmations from dcinoz,
I will just chance it and buy one.
If necessary, I am even happy to keep moving carriers until I find one that works with the pinephone's modem f/w    (and if I do, I will be happy to let each carrier know WHY I dropped them).

Hey pjsf,
thanks so much for that reply! I don't know why I didn't think to check github,
(or if I had, I probably wouldn't have had any idea what to start to locate what I needed to flash the phone with if it wasn't for your reply and this thread in general). 

So: thanks so much for sharing that. 
Glad you did the testing on that f/w.  

I had a brief read through the f/w flashing instructions, and it is not over my head.
Happy to try that if necessary, and take care not to brick. 

Any other input or experiences are much appreciated, but I feel like I've learned a bit already, and I know where else to research now, and have a few things to try.

Thanks everybody!

hi,

could you all confirm, today, especially few weeks after the general outage of 2g/3g in australia, that you can have phone calls, with audio working well, on your device? (which device?) even in roaming abroad?

depending on your OS (eg postmarket, etc)

does vowifi works?

thanks you vm!
