How do I confirm if a certain phone supports VoLTE?
You'd think this would be easier than it seems to be in reality. I am interested in getting a Sony Xperia 5V or Xperia 1V. Where I live, phones can't make calls unless they support VoLTE. The phones in question support basically all the bands I need them to support and I've found several encouraging Reddit posts from people saying they got the Xperia 1V to work here (haven't found any for the 5V). Some confirm VoLTE, others simply say they were able to make calls. The VoLTE requirement for phones is very recent with different carriers killing off their 3G networks at slightly different times the latest being about a month away so it's hard to judge how much I can trust those posts. I've also seen a video from what seems to be an Indian person showing you how to enable VoLTE on a 1V.
The thing is though, these are encouraging signs but Sony themselves have kept decidedly shtoom on the matter not mentioning the capability in their marketing or their web manuals for either phone, it is also not mentioned on GSM arena, however I noticed that this is not mentioned in the information about my current phone on GSM arena either, even though it definitely does support it because I've been using since even before it was a hard requirement. Is there any way to figure this out definitively? I've tried contacting Sony and maybe at some point they'll reply but frankly I'm not holding my breath and I suspect if they do reply they'll say something about the phones not being for sale in this country (which is true), or mentioning some of the other things the phone can do without answering whether it will do this one particular thing, which is what some websites selling the phone did as well. That type of evasive behaviour would normally lead me to conclude the answer was the feature isn't supported but those Reddit posts and that video, while not definitive enough in their own right seem to strongly indicate that it is supported.
Really depends on the carrier. For example, here in the United States, T-Mobile and Verizon seem to pretty much take anything that will work on their network, and most things will. But AT&T runs a whitelist system, and so I highly do not recommend them at all. As for VoLTE I Have found the only definitive way to make sure is to actually purchase the thing and see and return it if it doesn't. Either that or stick with the big brands.
I have an Xperia 1V and have a "4G Calling" toggle. I suspect VoLTE is now assumed as 2 & 3G services are getting turned off all over.
How is that phone by the way? I'm kind of swooned by it but I'm wondering if I really should spend all that money and go to all that effort to have it shipped here when I don't even do a lot of photography. It just seems so nice, and the bloody pixel and oppo and Samsung phones I can choose here seem so... meh.
My day to day experience is good. I have worries about the long term issues but it was one of the only ones that had a headphone jack and microSD. I'm not sure I would have sprung for it otherwise.
The OS could be better as I do get some occasional freezes but nothing particularly bad and that could be the launcher I'm using. Also the software support is shit: they've never announced how long it'll get updates for - previous phones were only 2 years of security updates - and when the updates come they don't have a changelog (in fact, their website doesn't even have the latest updates listed but I believe a very minimal changelog turns up when they eventually update the site). Also, there are various things people want fixed or features they want ported (I think there's some camera options from the 5V that never got made available on the 1V despite using the same sensor), though I only know about these because I've had to look at reddit to see what's changed in an update.
In terms of the security updates, I'm basically counting on LineageOS support turning up at some point.
This all sounds very negative but the camera, screen, battery life, and speakers are all excellent. The OS is fairly close to stock android, which makes it less annoying than Samsung. I'm just annoyed that a device that seems built to last, is hamstrung by the software updates.
VoLTE very likely. Do you know if the carrier uses whitelist? Might have a way to check if the IMEI is allowed from carrier.
My understanding is that we don't use whitelists here (I'm guessing except for stolen phones) although I only have random internet posts to go on for that as well. What's the basis on which you say VoLTE is likely. It's looking likely from the collected internet forum posts and that one youtube video that I've seen but I've been unable to find anything the least bit official. Even if not straight from the horse's mouth then at least a very reputable 3rd party like GSM arena but so far no luck. I've at least been able to confirm the absence of evidence of VoLTE on GSM arena's part is not evidence of absence of the feature because of my own personal case confirming that I can get a false negative this way.
Kimovil shows band support for all phones for all generation networks, 2G upto 5G. It is a better site than GSMarena for searching device models, but lacks reviews and amazing comment sections of GSMarena.
Generally, the best you can do is search.

SearXNG was useful once more, and I expected Sony devices to support VoLTE anyways as they've been doing that for years.
