The Wi-Fi Calling is working but sometimes it will say service disable and sometimes T-Mobile just depends on if it hits a tower or not. My last phone whether connected through just Wi-Fi Calling or on a tower would always say T-Mobile, is this a common characteristic of this phone?

I don't know, I disabled WiFi calling. When it says service disabled are you...
1.) Connected to WiFi?
2.) Are you able to make WiFi calls?
Because if my guess is right, it says service disabled because you aren't on the WiFi, and then when it says T-Mobile WiFi Calling Service or whatever, it's because you're on the WiFi and able to make a call with your signal.

No I can still make and receive calls but when I notice I cycle the network and generally it refreshes it, it's just weird.

I notice that after update to android 8.0 everytime making a call my data switches over to H or 3g once the call ended it switches back to LTE and 8 notice that when on call the enhanced 4g LTE option is gray out. Does anyone have this problem? Im on T-Mobile

As I know that is not a problem . reason behind Switching network lte to 3g is that there is no call support available for 4g.
I am on 7.1.2 and I have same thing.
Sorry for my bad english.

You are aware that voice over lte (volte) is a thing right?
On most carriers you can absolutely call over lte, so IDK what the hell you're talking about
EDIT: at least here in the states, we have volte, not sure where you live, but sucks if you don't.
On topic though, I'm not sure what's up with your volte. I'm on O official and I just checked and my advanced calling is working fine and not greyed out.
I show it as enabled on mine. How did you update to O? I dirty flashed the factory image via fastboot. I am roaming though currently.
I did have some issues with Carrier Services though a couple of months ago. Have you tried rolling that back, rebooting your device, and seeing if you can enable Enhanced LTE?

Enhanced 4g LTE is is only gray out doing phone calls, so doing calls my data will switch to H or 3g right after i hangup the call it switch back to LTE and enhanced 4gLTE option be enabled again. I was able to get volLTE on 7.1.2 on T-Mobile network after android O it broke

Yep, T-Mobile. And it stays on LTE all the time. It's lte before a call, lte during a call, and lte after a call.
I manually flashed (clean flash) the imaged though.

I opened the image up and flashed each individually
Fastboot flash system, flash vendor, flash boot, and flash recovery.
On elemental x 5.0.3 right now.
I had this problem and I had a hunch after checking the *#*#4636#*#* menu that everything was enabled. It did say wifi calling was unregistered but was enabled. Same with the volte option, so when I got home I made sure to make a wifi calling enabled call. Then disabled wifi to verify my hunch and made a regular cellular call and viola volte was working. Might be something to try if you have not.
My LTE hasn't functioned ever since I updated to Android 8. I cannot get access to the internet, links pasted in whatsapp chats do not work. I still get whatsapp messages and emails but no access to internet either from links or from Firefox/Chrome. Plus, the LTE band is perenially off.

I am on T-Mobile running 8.0.0 OP6.170623.019 build. I can confirm that VoLTE is working for me.
My phone stays on LTE while on a call.
Wi-Fi calling also works, as does native Visual Voicemail.
You may want to try going to the APN settings and "Reset to default". Afterwards, check the top one if it is not already selected.
The IMS ones are for VoLTE, Wi-Fi calling and SMS over IMS.

Sorry for the off topic question, just wondering if the LTE aggregation issue with 7.x radios and T-Mobile is fixed in oreo?

I have read it is better, but not completely fixed with the new baseband image. Personally never had the issue myself. I am in NYC and we have B4, B12, and B2 all deployed. I am in and out of the subway so my phone drops and re-connects many times a day without issue. I did have some issues after the 6.0.1 update, but solved it by forcing my phone to 2G, then 3G, then LTE. I never had an issue after that.
Just wanted to share my experience with WiFi Calling. I am in the US on T-Mobile and WiFi calling has been working for me surprisingly. VoLTE has also been working wonderfully. I've tested this on a Global Mi 9 running Stock and the Xiaomi.eu rom.
Enter these codes into the Dialer to enable the options in Settings. (Settings < SIM Cards & mobile networks < Sim Card Settings < VoLTE Enabled/Make Calls using WLAN)
VoLTE *#*#86583#*#*
VoWIFI *#*#869434#*#*
Things should work after you enable the two options. This depends on whether or not your carrier supports it and your e911 address set (US only?).
Some issues you might run into is that the option for Network Preference is greyed out and you will unable to change that option. I've had some success if you disable it and re-enable it and click on that option really fast, it will go through. When you first enable VoWiFi, it is important that you get into this menu and change it to WiFi preferred or WiFi Calling won't work.
UPDATE:
Manually creating your carrier APN worked great for me. Been testing it for about 2 weeks and I haven't had any issues with VoLTE/VoWiFi. For example, for me on T-Mobile, I created a new one with the following settings. The important part I'm guessing is the APN type. Also make sure that your carrier has enabled WiFi Calling on their end as well.
APN: fast.t-mobile.com
MMSC: http://mms.msg.eng.t-mobile.com/mms/wapenc
MMC : 310
MNC: 260
APN type: default,supl,mms,ims,cbs
APN protocol: IPv4/IPv6
APN roaming protocol: IPv4/IPv6
On a side note, since you're on T-Mobile US, are you getting LTE+? I was showing LTE+ on my Mix 2S and Mi 8, but doesn't show up on my Mi 9.
Can verify, works with Chinese Mi 9 8GB 128GB version. I'm also on T-Mobile. Now there is "HD" written on the signal icon.

It does when I'm outside. RN it isn't showing tho, I'm in the basement. I'm pretty sure I've seen it before when I'm on the bus or something

It just randomly loses WiFi Calling. To solve this, I've been keeping my phone airplane mode with WiFi on and haven't experienced any type of disruption of service. Calls sounds great.

Worked like a charm on Romania's Orange network. Both VoLTE and VoWiFi seem to work well.
Thank you for the tip.

It's a carrier specific option. So go to phone-> settings-> Sim cards &.....-> Orange and should be the last two options.
Hmm...I've activated both too but only get the volte option, no wifi calling toggle switch. Tmobile USA running no root, stock miui 10.2.3. Did anyone on tmobile USA get wifi calling to work? Also, if you did, does it also activate wifi texting?
Update: guessing the volte doesn't require a restart but wifi calling requires a restart. To those who run into the same prob as me.
Ídem here, no volte options, my carrier support it and works on a s7 edge, any ideas?

After update to Miui 10.2..24.0 options for VoLTE and VoWIFI appears in menu and i can activate both.
unlike you, since the last update 10.2.24.0 I lost the option volte/vowifi, when I try to reactivate it, the phone tell me it's enabled for the SIM 2 but I have no sim two,
if i swap the sim card it tell me activated for the sim 1 ...
Same here, after the new update 10.2.24.0 i have the same message like you.

I activated volte and wifi calling, but when I go on flight mode and activate wifi, wifi calling is not working and there is no sign in status bar too. I am Vodafone Germany and on my Samsung it was working.
How did you get it working?

Did a quick test on mine (T-Mobile/Germany) and it's working. I just used the dial-codes and enabled wifi calling. Had to change the preferred connection type to wifi-prio though - wasn''t working with cellular-prio and flight mode before.
It works!

Download a signal app from the Play Store and make a phone call. If you still have 4G when making the call Volte is working. If the signal drops to 3G after the call connects Volte is not working.

I did It and volte is not working...
I have a Mi 9 global version running the latest stable global Room. I'm trying to turn VOLTE on, but I'm nota being sucessfully.
I've tried enable It via MCC code (*#*#4636#*#*) but It doesnt work. The option to enable VOLTE os greyed out.
How can I enable It? My old s7 suport VOLTE with the same sim card.
So i got my Mi 8 Pro yesterday (Global Version). The one feature I cannot seem to activate is Wifi Calling, I have done both the *#*#86583#*#* (voLTE) and *#*#869434#*#* (voWIFI), both options are enabled in *#*#4636#*#* and when i go into my sim settings both VoLTE and Wifi Calling are enabled
voLTE shows the symbol in my task bar however wifi calling never seems to enable? Is there some other setting I am missing or do I need to get EE to disable and re-enable it on my account since I've swapped phones? It's vital for me as I work in a lot of places without cell reception so i rely on wifi calling.
Any help is appreciated

Hello, my friend is also like you, he is the development version of WiFi can not be used but the stable version of the MIUI system can be used. You can try to re-wire the stable version of the MIUI system, I wish you good luck.
I really need WiFi Calling in order to reasonably use this phone for calls from my house due to a poor Network signal. There is no Wifi Calling option in Calls -> Settings or in Settings -> Network & internet -> Mobile network anywhere. Also when I do *#*#4636#*#* and go into Phone information Wifi Calling Provisioned option is grayed out.
Nope. Last time I saw wifi calling available was on the XZP. Wasn't an option for the XZ3, and still not an option for the Xperia 1. Try giving tmobile a call or maybe sony support and ask if they can add wifi calling support.

Which frimeware is that ? Is that US unbranded
Nope, no wifi calling for me. I originally had the J9110 model (international dual sim, hong kong) but i recently flashed it with the US firmware. No dice, unfortunately. But since changing to the US firmware, I now get VoLTE and group message in Android Messages. It's a start.
Ya VoLTE is working fine and appears as provisioned in the hidden menu. So it seems like I will have to do something similar to what I did on the XZ Premium in order to get WiFi Calling...but I will wait until there is a DRM backup process.

I see the same thing as you. How did you do it on the xz premium?
I had to root it and flash a zip that someone made for it, it might be possible to use the same zip but I'm not going to root mine until there is a DRM backup method. I barely every talk on the phone without LTE service so it's more so just really annoying not having WiFi Calling. I think a bunch of people were using the same zip for the 2017/2018 xperia phones to get it working.
I have XZ premium and XZ1 and wifi calling option is displayed when I use the Jio sim but not displayed when using Airtel sim (using Airtel broadband), so our phones do have wifi calling facility but working only with Jio sim, although Sony is not shown in the compatible phones list. I am in India.
That also stresses me out on My Xperia 5. Don't know If You talked about My Zips for VoLTE and the other Features but i didn't get it to work actually on Android 10. Possible that i just don't have the right Firmware atm (Customized EU / My Devices Firmware isn't Out yet), so i'm using Custom UK Firmware but that should also work... I'm a bit confused so i switched to GSIs which Made it even worse... Looks like we should start making Custom Vendors for our Xperias since the Methods changed over Android 7-8-9-10
Can you flash the dual sim model to work with a single sim firmware and does Wi-fi Calling Work later?
yes, that's what i did with my xz3. volte works with tmobile, but not att.
