Found out the guy lied. So the US unlocked N20U does work with VZW wifi calling.
It definitely does work with my N20U on Verizon.
The only differences between the Unlocked and VZW version are:
1. Native Verizon video calling doesn't work on unlocked, but the integrated Duo video calling is better anyways.
2. Verizon's model doesn't have the Samsung "Smart Call" feature for Caller ID. Instead, it uses Verizon's app.
3. Verizon's version has the Verizon bootscreen and a ton of bloatware, especially games, news apps, and what not. Fortunately, most can be uninstalled, and the rest can be disabled using ADB.

I can confirm all of the above. I have an unlocked phone, on U1 firmware, with a Verizon SIM. Wifi calling works. There is no "Advanced Calling" menu in Connection Settings, but there's a toggle for VoLTE and it was switched on by default. No 4G icon, but rather a LTE+ icon is shown in status bar. The only thing I haven't found a workaround for is the native video calling. I cannot initiate it (phone app does not show the option when I'm on a call with another Verizon phone) and if another Verizon phone attempts to initiate a native video call, it tells them that I cannot accept video calls. I checked my VZW account settings on a PC, and despite the video call option being on and not blocked, native calling doesn't work, as described above. Duo works fine for video. I was able to get Visual Voicemail by installing the app that I go from another thread. I installed it before checking to see if the U1 firmware added it by default, so I can't say for sure that it wasn't there already.

So I had an interesting observation. I flashed my Verizon Note 10+ to U1 firmware and noticed a drastic reduction in data speeds. After getting the Note 20 Ultra, I noticed the data speeds were nearly doubled. I then disabled a ton of Verizon and Samsung apps, and my data speeds dropped drastically as well. Through the process of elimination, I found that the "My Verizon Services" app seems to have a major impact on data speeds. As long as I keep that enabled on the Verizon firmware, data speeds are blazing fast.
Is it possible that Verizon uses apps to prioritize or de-prioritize data speeds? I'd be curious if one could do a side by side of the Unlocked vs Verizon firmware.

Thanks for sharing your observations regarding wifi calling. How can one tell it is working? I am used to older phones advising that wifi calling was in use via text in the phone app. I'm not seeing this notification on my new unlocked T-Mobile-branded N20U with Verizon SIM.
I also noticed the VoLTE toggle in the phone app, switched on and greyed-out, can't be deselected. Of course they don't want to support anything but VoIP anymore. What is the behavior, if the cell signal is decent it won't use wifi? It can't be forced to prefer wifi, can it? I used the trick of putting it in airplane mode, then turn on wifi to try and force it to wifi call. It said it couldn't make the call in airplane mode, which is not encouraging regarding wifi calling being functional on this phone/provider combo.

From what I've found, if you put another carrier's SIM in a truly unlocked carrier branded phone, it should prompt you to apply your carrier settings upon boot. For example when I put a Spectrum SIM in a Verizon phone, it "converted" the CSC (Carrier settings and boot logo) to Spectrum.
My recommendation is to attempt to get the SIM to switch the CSC automatically. If not, use the patched ODIN to flash the Unlocked U1 firmware, and optionally you can flash Verizon from there if Verizon's Video Calling is a must.

Thanks for the detailed response. I was a little concerned about the T-Mobile branding, and what that truly meant at the software level. I installed the Verizon SIM to this factory-reset phone. If it was going to switch CSC I think it would have happened then. It went through the usual setup steps, but still displays T-Mobile screen at boot. I'm not sure what else I would do to "get the SIM to switch the CSC automatically".
Would you agree with my conclusion that wifi calling isn't working based on the outgoing call failure when in airplane mode with wifi on?
If there is better, more-unlocked firmware I'm not opposed to flashing it. It's been a while since I've played with rooting and custom ROMS, but I'm guessing stock firmware is a lower-risk activity on an expensive phone.
I'll refer to this link to try and flash to unlocked U1 firmware, hopefully that will allow wifi calling compatibility:

Hello all..
I have this issue with my Note Edge 915T (T-Mobile Variant). It is unlocked and I use it in Venezuela with Digitel (LTE BAND 3: 1800) and the phone DOES connect to LTE with no issues (I get the 4G/LTE icon), and I can browse with no problems, but no one can call me, nor can I make any calls or text. In other phones, when I call, data drops and I can call and when I finish, data comes back up. HEre, LTE stays up and my call does not get through. Then after some tries, it drops to EDGE and won't pick up LTE until I reboot or something.
If I try a different operator, it goes to HDSPA (3.5G) and I get voice and data (data drops while calling, but it ir normal), but I want to use my operator with LTE.
Im running MM and I deactivated VoLTE as my carrier does not support it, but is there something else I'm missing?
This may sound stupid, but have you set your APNs? You can also try resetting your network. Dial ##72786#. Also Does your carrier require any certain apps. Example FreedomPop requires a specific app for getting/making calls, as they are mainly VOIP MVNO...

Hi! thank you but yes, the APNs are perfect, I can use Data, the issue is that I cant call as the data signal stays in 4G/LTE and with my carrier, when calling, it drops data signal and it calls, here I can't. Im starting to think it has to do with CSC being with TMO, and I should use another one either from my country or a general One (BTU) for example. Will try to flash a rom from a different carrier to see if it works.
The only other option might be *#BAND# (2263),which could be dangerous, if you do not note original settings. Sometimes a complete ODIN can restore.
I normally use Nova Launcher - Widget- Activities- Somewhere under phone or settings. Shortcut Called PhoneInfo or DeviceInfo, which is much safer&consistently works! The app w/ same name no longer works. It took me forever & I always export my desktop, so I have that shortcut. The last option is an app called Samsung Phone Info+, but is paid or free if u know.... I really hate paid apps. It has under menu secret codes as well.
I have a SM-G955U that's GSM unlocked. It was originally an Xfinity phone, but I'm now using it on mertopcs. Mero supports active data while talking on the phone. But my S8+ disables my data while making a call. I do not have root, is there a way to keep my data while talking on the phone?
Try this settings/ connections/ mobile networks/ VoLTE Calls. I think that's the option you're looking for
That option doesn't appear when I go there...
I've checked through the phone app and the settings menu, nothing like that appears anywhere.

I think this option depends on the carrier itself you're using some carriers doesn't support vollte so this option will not be enabled by default. My carrier supports vollte.
Next to 4G or LTE icon vollte will appear like the picture below
https://mega.nz/#!zZBAAaaA!UJM62RS1-M0NwU7Tu1X_wpXiGKf3QXWQlSf3OB41qe0
The original carrier for this phone did not support vol LTE by the carrier I'm using now does support it. It was originally Xfinity and now I'm with MetroPCS.

Maybe flash the MetroPCS firmware or unlocked firmware.
You don't need use VoLTE to talk and browse at the same time, if your carrier doesn't support VoLTE your cell phone will perform a CS Fall Back to UMTS and then (if your carrier support MULTI RAB) your cell phone will make MULTI RAB, one RAB CS to voice and one RAB PS to data. The problem is when you are using 2 sim cards, if you make a call from one sim card and the data came from the other sim card, the Galaxy S8+ will block the other sim card in a call.
So to call and use data at the same time you will need VoLTE in LTE or Multi RAB in UMTS but must be the same sim card.
The method outlined below can probably be used on other variants.
My phone started out as an unlocked Tmo S9+ - SM-G965U
Flashing the latest tmo firmware (G965USQS7ETH2) would only yield volte, not wifi calling with cricket. The exact same firmware would give volte and wifi calling withi my free freeup sim (also att based). So the device and firmware is most certainly capable of it, but there's profiles in place restricting it.
As soon as the sim was swapped to the cricket one, phone would reboot, apply csc changes and no wifi calling. Flashing the AIO CSC didn't help either. They purposely block wifi [email protected]#
So, solution is to prevent the CSC change from free up (CSC: ATT) to cricket (AIO) from taking place. But how on an unrooted device???? I decided to use the debloated factory unlocked U1 fw rather than U (less crap to disable later).
My final results is a concoction of fw pieces and some adb magic.
It is important that account/sim is already configured for volte/wifi calling. I did this over chat by providing them an iphone 8 (or 9?) IMEI and confirmed hd voice and wifi calling was enabled on the profile. Some social engineering may be needed.
I use frija to obtain all fw's.
a) Base firmware: SM-G965U1_2_20200709201504_m6wxoyd74w_fac.zip based on G965U1UEU7ETG1
CSC: TMB
Additional:
b) SM-G965U_2_20200811140304_5ohvmlyr5p_fac_G965USQS7ETH2_TMB based on latest G965USQS7ETH2 tmo firmware
CSC: TMB
1) Obtain and extract files from both of the above zips. Keep track of which is which.
2) In odin, specify everything from A except CSC. Use the CSC (home or non-home) from B. This is needed to get the advanced calling features to work. Flashing CSC from A resulted in no wifi calling (possibly no volte either, can't remember).
CSC home or non home version?
I haven't tried this with an already configured phone, will probably work too. In that case use the home version. Non home results in a factory reset.
3) You will need a sim that specifies the ATT CSC. In my case the freeup sim is identified as such in the phone info app. I imagine a deactivated or blank sim should do the trick. The goal here is to get the phone to flash the correct CSC parameters. Have this sim in the phone prior to the reboot from odin.
4) Depending on which csc used in #2, the phone may reboot to apply CSC changes, let it. We want to lock in this profile.
5) If all is right, you should see the wifi calling toggle in the quick tiles and have the options in the connections and phone settings.
6) Enable usb debugging and connect via adb shell
7) This one took forever to determine, but this is what makes it all work!
Code:
adb shell pm disable-user --user 0 com.samsung.android.cidmanager
8) Insert your cricket sim and allow to register. You will see it doesn't ask you to reboot to apply any csc changes. Under the 4636 menu it should show volte and wifi calling enabled. Make sure the wifi calling toggle is enabled
9) Reboot the phone for good measure and test again. Enable airplane mode and wifi. Try placing a call. It should go through.
Caveats: Unlike the att CSC, this one doesn't ask for an address. I'm not sure what address it's using - the one tied to the cricket account? The signal around here is good that wifi calling only kicks in in air plane mode.
Does this break something else? Possibly. Lets hope a proper fw update is released where these shenanigans are not necessary. With root, the proper CSC features can be correctly enabled for the control xml file. The battery in this phone is already at ~80% life remaining, so not willing to give up another 20%.
Good luck!
Reserved
Wifi calling uses the following ports. Make sure they're open in your firewall.
Outbound port 4500 udp
Outbound port 500 udp
Outbound port 5228 tcp
There may be others, but these were the nonstandard ones I had to explicitly define.
do you think you can use the stock U1 firmware ++ the tmo home CSC with this method?

strange, I used frija to download XAA and TMB firmwares but they end up being the same filename?
also, going to need to find an ATT SIM. Tried my redpocket GSMA but since it was never registered to an account it is giving me an error.
I can assure you this does not work. Your putting your sin in a cricket phone which provisions wifi calling and volte. When you insert t the sun in another phone it works for a mere hours. Then they realize your in a different device and reprovision your account again. Simply fishing cricket firmware does not fix this.
Only way to get around it is like I do.
Put your sim in a cricket phone. Provision. Swap sims. Then call them immediately and tell them your using the cricket device but it's showing your byop still and they need to change the imei to the cricket device. Then they're system will not reprovision your account again. Wifi calling will continue to work indefinitely

To whom are you replying? My cricket account already has a hardcoded imei on it (via customer service).
ok so not worth the trouble trying to get an ATT sim then? One thing that does work is VOLTE started working after pulling sim, putting in iphone6 enable wifi calling / volte. Swap back then volte started working and continues to work.
Hello,
I recently purchased a T-Mobile unlocked Oneplus 7 pro (GM1915, 8GB ram/256GB storage) on eBay to use on Verizon, and I can't seem to get wifi calling to work. We went through the setup with Verizon, and let them know it was a CDMA-less device, and everything works perfectly besides wifi calling. I do not have the option to turn on wifi calling in the settings of the phone or the log kit. When I dial *#*#4636#*#* in the phone app to get to the phone info, the VoLTE provisioned slider is enabled and able to be turned on and off, but the Video Calling, Wifi Calling, and EAB/Presence Provisioned sliders are all greyed out and disabled. I called Verizon to check on their end if it could be enabled, and he said it was enabled on my account, but it still wasn't working on my phone. He put in a ticket to verify the E911 address, but after reading a lot of threads on forcing VoWIFI on other models, I just wanted to see if it was even possible, as I saw next to no threads on my specific model of 7 pro. If anyone has any guidance for me on this issue, I would really appreciate some help.
Thank you!
Won't work. The phone is not a Verizon phone and will be refused access to the vowifi server. Only the pixel ever functioned. Sms over WiFi will work with the Verizon messages app or Google messages and rcs. You best option is Google voice for vowifi.
Welcome to Verizon where unlocked 5g phones don't work on 5g either.
Fully possable
Has anyone else had a problem using the internet while on a phone call? I just switched from the s22 ultra which had no problem in this department.
Is there anyone else experiencing this problem Or is this normal for the pixel?
Do you try to active VoLTE ?
For that you need VoLTE activated. And it is not supported in every country. In order to enable it you need to root your device. I am still searching for fully tested and functional mod for P7P.
Pixel is weird compared to what I was used to from Oneplus. Having 2 Sims in where the physical Sim is for calls and Sms and the eSim for data. When on a call (on phys. Sim) I don't have a data connection on the eSim anymore. When I check "use data during calls" on the physical Sim, as soon as I'm in a call the data card changes from eSim to physical Sim and Internet is available. As soon as I hang up, data connection is transferred back to eSim.
Unfortunately the check box for " use data during calls" is not available for the eSim, also both are provisioned as VOLTE.... Never had such problem with OnePlus, there data stayed on 2nd Sim when I was on a call on first one....

It should still work with UMTS/HSPA if your network has this "3g" network type available, but relatively slow.
You need to upgrade from dial-up to talk on the phone and to have Internet access at the same time.
Big sarcasm here is anyone didn't notice, haha =)
