Despite enabling VoLTE using root methods, my phone categorically would not do IMS registration required for VoLTE as evidenced in the testing phone information menu *#*#4636#*#* and the IMS Service Status menu. So, I reached out to my carrier, GCI, who told me to reach out to Google who then told me to reach out to my carrier. (GCI is a carrier in Alaska for those unfamiliar)
So, here's how I got VoLTE on GCI. I called GCI tech support and spoke with a tech, Walter, who was also stumped as to why my device wouldn't perform IMS registration. We settled on that maybe my IMEI number needed to be registered in their network. So, he coordinated with a colleague who manually registered my IMEI in their IMS database and BOOM! I got VoLTE now.
So if you have GCI (or maybe some other carrier) and your phone just won't perform IMS registration, then your phone's IMEI might need to be manually registered in the carrier's IMS database. (Walter with GCI suggested I post this somewhere as a solution)
Why can an off-the-shelf unlocked Apple iPhone bought from Apple or Samsung device bought from wherever work like magic on GCI? Who knows. All I know is I have VoLTE now. Per Walter at GCI, this *should* enable my wifi calling as well, but I won't know until I get home. It is also worth noting that I manually added an IMS specific APN that my 5G enabled iPad Pro showed on its SIM card, but it's unclear if that matters or not. I figured out it had to be the IMEI because when I swapped the SIM cards between my iPad Pro and Pixel 6 Pro, the Pixel still refused to register IMS, so it had to be something device related in connection with GCI's network. (It didn't connect to 5G either when I swapped SIMs.)
I don't know yet if this fixes 5G because I'm in Fairbanks and there is only one 5G GCI tower in the whole city as they're just rolling it out, so until I get off work, I have no way to test.
EDIT: This fixed wifi calling for me as well.
Sadly GCI said no this doesn't work and the post is wrong. Is everything still working for you? Would really enjoy Wifi calling due to location constraints.

It's still working for me. I get both VoLTE and wifi calling still. The tech you talk to on the phone can't whitelist your IMEI. One of their network techs has to do it.
I did have to dig deep into my memory about that call. It was a weirdly helpful call. Too helpful. If I recall, you're not wrong. The tech I spoke to coordinated with a network tech while waiting for the supervisor to approve it. Supervisor took too long, my phone got whitelisted and just before ending the support call the tech was like "Ah, uh, my supervisor says we can't support your phone, but, uh, I guess it works now so have a good day."
Edited to add screenshot of wifi calling and GCI network in top right corner to show I'm not crazy. Again, it was suspiciously too helpful, so I feel like rules were broken somehow.

Hey thank you so much for the response. Yea I feel like they probably didnt realize what they were doing, and it worked, and then they dont want the other 4k Pixel users calling to get the same thing done, so for now blame google for not making it work. Huge annoying part is they advertise bring your own phone, have a support page up for lots of other phones, but the only ones they will make work fully once you put a SIM in is either a Samsung or Apple. I'll keep bugging both sides of the coin here and see if one wont make something happen for us Pixel users.

Ok so here is the issue. I have 2 phones (Note3 on Tmobile, and Samsung Rugby Smart...workphone on AT&T). My fiancè has an iPhone on AT&T and she rarely recieves my calls and texts. I thought at first it was the iPhone...but it seems like it is my Note. We did a test...i sent a text from the note and rugby, the rugby went through, note did not. Same thing with calls....I ended up doing a warranty exchange with Tmobile (not very happy about that..since they sent me a re-manufactured device), and this is still happening.
Any thoughts...suggestions...?
Thanks in advance.
(P.s.....i am not routed, iphone not jailbroken)

Sounds more like a network or interoperability issue. I test iPhone users without issues. Not sure which carrier they are on though.
Try turning off wifi. I have seen posts about issues with wifi and sms/mms. I've never had a problem, but might as well try. Also try texting from the note to your work phone, and back. Are you using the stock messaging app or a third party one? Try stock.
Another option is using the sim from your work phone. You will need Tmobile to give you an unlock code. If you explain what you are doing, I think they will give you one. Or try an att prepaid sim if your work phone uses a different size.
It sounds more like a Tmobile to att network problem to me... But that can narrow it down. Try disabling LTE for testing. I wonder if VoLTE is part of it...

My wifi is off....since we have unlimited data, and stock messaging app.The sim cards are not swappable. The Rugby is OLD....Its on Gingerbread..lol and it had a regular sim, not micro. These problems were before VoLte. She does not have rhe iphone cloud texting app setting activated either. I do appreciate your suggestions! Thank you.
I have tried everything....been to both Tmobile and Apple/At&T stores, troubleshot networks, master reset both phones.......
Just all out of ideas.

Before the Note 3 were you using an iPhone? If so, it may be an Apple issue. Google for Apple iPhone iMessage

About 2 weeks ago, I started noticing that my phone wasn't receiving calls, texts, or voicemail alerts, unless I manually set it to 4G, or if I made a call and my phone would switch by itself from 4G LTE to 4G, like it always did. So the problem was that it wasn't switching to 4G when receiving calls or texts. I would get a barrage of texts, voicemail alerts when I would call someone. After flashing different roms, I decided to revert to the latest stock T-Mobile fw and it worked fine. So I'm making a call by swiping right on the contacts name, and instead of seeing "calling" it says "VoLTE call HD" and my phone stays on 4G LTE during calls and is always on now, for obvious reasons of course. This sucks because I can't flash different roms, I'm stuck with the latest stock, which is BS. From what I've read so far, there are no custom roms with this VoLTE working.
I think Tmo introduced VoLTE and HD calls last summer, or even before that, but I'm not sure why would that suck? you just have more choices which poison to take. I'm sure at some point developers will figure how to make both work, maybe already did. HD calls are a little finicky, phones on each end need to support it and VoLTE is important only when there is no other signal except LTE, so neither should be a deal breaker for most part. I think bigger issue would be the reason you switched to stock in the first place, where phone doesn't work anymore.

Why did I switch to stock? Because I wasn't receiving calls,texts,or voicemail alerts since they implemented VoLTE. It stays stuck on 4G LTE, instead of switching to 4G. Even when I turn off the feature in the latest stock, it acts the same way as I explained in other roms. I cannot receive calls, so LTE becomes useless. There is literally NO roms that I can use, unless I have it set manually to 4G (WCDMA/GSM). So I cannot use any other roms, I'm use to flashing different roms, experimenting, now that's out the window, unless I sacrifice LTE. Why pay damn near $80 a month for something I am not using? This is ridiculous.

I will keep speaking my mind and inform T-Mo users about what will happen when VoLTE arrives for them. I HAVE read, and there are a BUNCH of reasons why I chose not to use that particular rom when it first came out and about 2 weeks ago when VoLTE hit. I'd rather be on stock as of right now. I don't think any of our members have a clue about VoLTE and how limited they will be when it hits them. Either way, thanks for reading my thread and ur suggestion.
I purchased my 7T (model HD1905) online in October of 2019 directly from OnePlus. The phone is absolutely amazing and functions perfectly except it is not able to perform basic WiFi functions such as text or make phone calls. I work in the medical industry as a tech in a hospital laboratory. The laboratory is located in the basement of the hospital where I am unable to receive my carrier's (Verizon) signal. Hence, I am unable to use the aforementioned wifi functionalities and certain apps on the hospital's excellent broadband WiFi (2.4GHz / 5GHz). During this busy & intense time of the COVID-19 epidemic, the ability to effectively use my phone's apps and calling functionality over WiFi is vital and an absolute necessity.
In the past I have used an original Google Pixel (unlocked) and also my daughter's $60 (the cost a couple years ago) Samsung that I bought on eBay to flawlessly make phone calls and perform the functions that the OnePlus 7T is unable to achieve.
My question is:
Is it likely that OnePlus is going to roll out a fix for vowifi / WiFi calling for the OnePlus 7T on Verizon, the largest US wireless carrier? I see that Verizon now carries the OnePlus 8 having this desired wifi functionality and needless to say, I feel cheated. OnePlus is supposed to be synonymous with high tech and deemed as "A flagship killer". Will OnePlus develop a fix for the 7T's WiFi limitations / inabilities or should people that purchased a 7T resort to buying a $50 phone on eBay to fulfill the 7T's shortcomings? Though Samsung is more expensive, it seems overall to be fully functional on the majority of wireless carriers.
I appreciate any thoughts or insights.
Regards,

I could only get mobile phone calls to work with VZW. No texting, and no VoWIFI. I am trying an AT&T sim for a couple of months to see if I can get service in most of the areas that VZW has worked in my area. I have not proven if VOWIFI in AT&T works yet, as I was not in an area with no service and Wifi yet. To me this phone is a total fail with VZW, but I think it is more their fault than OnePlus.

In a nutshell; The issue is with Verizon not Oneplus. The necessary hardware and software is on the phone, but Verizon hasn't authorized wi-fi calling for the 7 series, claiming security concerns, and it does not appear they will. Verizon allows Wi-Fi calling/SMS for the 8 because they sell a Verizon version of that phone; my understanding is that they don't allow wi-fi calling for non-Verizon branded 8's either.
You can't buy a Verizon branded 7T so Verizon has no incentive to allow the 7T to use that feature on their network. The alternative is to get a VOIP number from Google, Skype, et al and set up a SIP account under calling accounts in the dialer
For Verizon, you need to call them and enable CDMAless provisioning in order to get texting to work. VoWifi.... we are basically up ****s creek without a paddle. This is on Verizon and not a OnePlus issue as the 7t is whitelisted to prevent it from gettting VoWifi and LTE Video calling.
I fought with them for a week and finally was able to get them to trigger VoWifi, but there is something universally blocking this feature on Verizon's network unfortunately. They triggered and I even tried the logkit...no dice.

What about with MetroPCS? I have issues with WiFi calling as well. When WiFi is on it even tells me, "Mobile network is not available. Connect to a wireless network to make a call."

I've been wondering how it could be that T-mo could get such an extensive 5G network up so quickly? Then today while perusing through my phone I came across this sweet little nugget.

This explains the slowing of older 4G devices on T-mo's network. They're just pushing more bandwidth over 4G to "special devices" and making a grip on suckers like us buying into "5G". Same thing ATT did with an icon change, but ours is baked in.
Someone doesn't seem to know how NSA works. Your screenshot even shows NR-RSRP with NR-SNR.

It only shows true when 5g data is being actively used.
It only registers it when in active use because of the fact that 4g is the default default when it comes to most phone functions.
Texting, phone calls, mms all go through 4g.
You can also verify that whole deal through my LTE configuration in the screenshot.

Gotta remember, it wasn't too long ago that people thought granting permission for internal storage would end up with their info gone or some other semi-sensationalist dribble.
This was the same way with early 4G phones. The first gen 4G radios used HSDPA+ which late gen 3G radios would connect to, but not fully utilize. How products and services are marketed are always divorced from what they really are, they won't outright lie, but they take advantage that the average customer won't read the fine print, are not engineers, and would complain to bbb(where ratings are bought) and never think about complaining to the FCC. The radio in my n10 pulls 10+ mbps consistently, no LTE branded radio I've had would get better 5 mbps. It's clearly using hardware that, for example my One+ 6T, does not have. According to xml's found in vendor partition, and info from system/vendor props Qualcom engineers have it classified as LTE, T-MOBILE marketing calls it 5G. Labels aside, network performance suggests this device has upgraded hardware. If your not impressed, try disabling ipv6 in your APN, and /proc/net/ipv6 files. You need root/adb anymore to do this. I attest to dramatic differences in network performance as it bypasses some network throttling. I don't know about you, but I waste the 30 gig throttle limit the first two days on the new radio.
Hi,
I'm in the USA using Tracfone. I recently purchased this phone (end of last year).
I rooted it. I installed the Sakura ROM. I had an understanding that there might be "some assembly required" with a custom ROM & I am mostly happy with it.
But recently I have started getting messages from Tracfone, "Tracfone: Your service is at risk! Your phone will stop working 2/22.".
This appears to be coming from the underlying carrier, AT&T, and relates to the 3G deprecation. VoLTE is supported by the phone and in the ROM but it seems this phone is not in AT&T's whitelist of allowed phones after 3G deprecation. This seems to be related to supported bands (this phone supports a great number of them but perhaps not ones useful to connect to AT&T).
Are there any workarounds for this? I could get a T-Mobile SIM from Tracfone but I am guessing I am going to have exactly the same problem from them?
Can any of these phones even be used after the deprecation of 3G has been done by all the major carriers?
Am I missing something?
I would love to be able to actually use this phone.
Ouch. Didn't think that would happen so fast.
I actually double checked to be sure my phones are white listed by AT&T.
See what other carriers say because I don't think there's a work around for AT&T especially if the bands aren't supported.
Maybe advanced tech support would have a suggestion or fix you could use. Some of the agents will go out of their way to help, some are duds. As always use Google search...
well afaik, you've only got 3 options
1. spoof the imei and make it look like a supported phone. not sure if i can talk about the specifics here and even if i could, it'd be a pita even for me to do it
2. find another carrier who doesnt whitelist phones
3. use voip apps like google voice to bypass the volte problem

Don't think the first option would work because it's the configuration and/or hardware that's the problem not the brand.
AT&T makes big bucks selling cell service so I doubt they turn down your business if your phone was compatible.

I checked the T-Mobile IMEI checker and, if it's accurate, it doesn't look great. I'm not sure what "not blocked" means but it claims it's incompatible.

Not blocked may mean it can be used for data only or it's not blacklisted?
What's it say for the expanded explanations?
well most xiaomi phones dont really work too good over here in the us because of missing bands with the exception of the mi mix series.
this pretty much explains the situation
Will Xiaomi Mi 10T Lite work in USA?
In this page we are going to show you the compatibility of Xiaomi Mi 10T Lite with the mobile networks of USA and with the telephony operators that provide service in USA.

the only 2 carriers that look like it would work fine with are cspire (which i've never heard of) or gci wireless (also never heard of)
that being said, it should *work* on the other carriers, but i have no idea how well

I ordered the T-Mobile SIM from Tracfone. I figured that worst case was that I am down $1.00 & will be left without a working phone (until I have access to an old backup phone in a few weeks that will probably work —Moto G6 Play); vs. by default being left without a working phone in a few days if I did nothing (until I have access to the old backup).
It looks like it was allowed. The only hitch was that transferring my phone number (from using the AT&T SIM to using the T-Mobile SIM) took a bunch of hours. I even have VoLTE enabled (which appeared not to be possible with the AT&T SIM —and I assume is the only way this phone will work after the switch, if at all).
I imagine the coverage may be spotty given the poor coverage in the supported bands but I may be OK with that for now (probably depends on how spotty spotty really is and where). I'm sure it might be one of those YMMV things (and one that could change in the immediate future?).
