Why does VoLTE require pre-approving phone models? Voice over VDSL (IMS, 3GPP's embrace & extend of SIP) seems to work fine independent of the device placing the call.

#72VoLTE is so damn frustrating. LTE works via plug and play with any phone that supports the correct bands, but VoLTE doesn't. I have a Sony Xperia phone here in Canada and it's just not possible to use it on VoLTE without rooting to install specific provisioning files and whatnot. And that's not even counting how you can't just go from country to country without changing firmware. I've always used a local SIM whenever…
My luck with both WifiCalling and VoLTE has been so touch and go between different devices and even within multiple devices of the same model... that i just gave up and started doing everything exclusively within Google Voice. Nuking the Messages app also had a nice little benefit: No more text spam that the carriers refuse to do anything about.
I recently found myself without any LTE signal the other day and was told by support that I needed to contact a certain department by… calling them.
I did have WiFi so my first thought was WiFi calling. Unfortunately, it appears on iOS that WiFi calling for some reason depends on hotspot, which I couldn’t enable without and LTE connection. Kinda deflated the purpose.
Thankfully, I had completely forgotten about Google voice, which someone reminded me about.
I remember a few years back though, a phone I had on I forget which carrier could fall back on 2g networks when LTE wasn’t available for whatever reason. It seems that ability is disappearing as old generation networks are shut down.

VoLTE has been "broken" (from a standards perspective) since before it even launched in most markets - it is just too "finicky" and configuration-specific. LTE/4G demonstrated the success of standards in that it "just works" as long as you have the right bands in place. Since most (modern) phones have the bands needed for the main global markets, you can pop in a SIM card and get connected anywhere. VoLTE is far more…

VoLTE is far more complex, and there's network-specific configurations "hard-coded" into the (usually) Qualcomm modem firmware, including IPSec parameters for communicating with the IPsec endpoint in front of the IMS SIP server.
I sort of get the feeling this is by design.

#74A few weeks ago I moved my sim from a broken LG V20 to a Oneplus 3t and att suspended my account. I wasn't sent a message or any kind of notification. My sim just stopped working. I had to call att support for 30+ minutes to find out that it was because the 3t doesn't support volte and get my account reactivated. The way att has been handling this transition has been really shitty. VOLTE is a banned subject on the li…
Someone else had all of their outgoing calls redirected to AT&T customer service. https://twitter.com/mcclure111/status/1415078945989566469
I just tried an "unlocked" iPhone 7 on my brother's Verizon prepaid, and SMS works, but calls don't.
He bought a Samsung, and that seems fine. He's keeping the iPhone for Siri. I don't feel like teaching him how to enable Google Assistant just yet.

#75Earlier quoted context omitted.
Old Teslas (like 5+ years) will lose net when 3g goes. You can do a computer upgrade but I don’t think it’s cheap ($500-$1500 range offhand)
That's not accurate. You don't need to upgrade the MCU/infotainment computer and the retrofit is only $200. "A source has informed me that due to AT&T shutting down its 3G network by Feb 2022, Model S's without an LTE-capable modem will lose connectivity features unless connected to WiFi. HOWEVER, Tesla will offer retrofits for $200. Affected vehicles are pre June 2015." "Tesla will be offering retrofits for these ve…
I really appreciate my 2011 Civic's lack of a cellular modem.
Re: “We're Shutting Down Our 3G Network”
#76The author appear to be using OnePlus 3T which uses a Qualcomm Snapdragon 821 with X12 LTE Modem. It support VoLTE with AMR-WB but not EVS. I doubt EVS is a hard requirement until VoNR in 5G. But not supporting it seems strange. In the old days Network require certification for phones to work. I am not sure if that is the case in US but for many part of the world that is no longer required. It could also be the lack…
The earliest supported OnePlus is the 6t.

Re: “We're Shutting Down Our 3G Network”
#77The 3G network in NL is also gone (except for kpn, which will keep it for 1 more year)
But 2G is staying until 2025 so old devices can still do normal phone calls and SMS.
Same in Germany. First operators have shut down 3G and the last will follow soon. But there is 2G for voice, SMS, and in theory data. Of course in today's bloatweb EGPRS is not fun to use.

My very old rooted huawei maimang 5 somehow manages to even get VoLTE roaming without problems, and it automatically got VoLTE settings on every network I tried. I still have to see how my new Xiaomi will fare.
Lots of networks blocks VoLTE on the network end if the device is not on their whitelist. Both two of my Xiaomi phones fails to get VoLTE on both networks in my country that offers it. Mea while my S21 has no trouble since it is whitelisted with the same two networks that refuse to provide VoLTE to the Xiaomis. Sadly it's a case of making sure you have (1) a VoLTE capable network, (2) a VoLTE capable phone and most importantly (3) a network that whitelists your phone. One network in my country started out only whitelisting only the specific phones they sold (and rejecting phones sold elsewhere even if it's the exact same model, firmware, etc) but I believe they have since loosened up by accepting phones sold by others as long as it's the same model as what they sell themselves. It's a absolute mess and to be honest the only reliable choices are Apple and the last few generations of Samsung phones (as that's what all carriers here sell) but if you stray to other brands it's very hit and miss whether your carrier will support it and worse whether you have the choice of changing carriers to another that also supports your phone. Makes me pine for the good old days of GSM.

Not quite clear from your comment, it stopped working even when you switched it back to your old phone? Otherwise, it just sounds like your phone didn't work because it was incompatible, not because your account was banned.
The phone should still work for other functions so if stuff like data etc stopped working entirely it does seem possible it was due to a SIM being blocked/disabled.

The success of standardization predates LTE by a lot if you look beyond the US which had competing technologies until LTE. GSM networks (2G) allowed roaming and switching between phones by swapping SIMs in all of Europe in the mid nineties, and most of the rest of the world a few years later. Just the US use of a unique 1900Mhz band kept roaming mostly unavailable.
