VoWifi missing - OnePlus 8T Questions & Answers

Hi, I somehow played / messed around with my OP8T and am now no longer able to enable VoWifi and VoLTE, also 5G is not working. Both options are checked in the SIM settings and the icons are enabled in the system settings but the phone doesn't connect and the icons don't show up.
It used to work till I played around ...
I just re-flashed OOS 11.0.7.10KB05BA which didn't change anything :-(
Any suggestions?

The notification icons are not even showing. Already enabled the "use packet data" setting under mobile network settings but still not able to connect. also tried resetting the apn settings still no luck GPS icons are also not showing when trying to enable via the notification bar.

VOLTE Three UK

Has anyone got this working, the icon is enabled but it's not showing up.
Volte only works iff you buy a volte compatible phone from 3 shop. It has to be one of there phones or its blocked. Unlike on O2 iff the phone is volte compatible it even works with some of there pay as you go phones. For this reason i am going to leave 3 after my contract finishes.

My last phone was a phone not sold in the UK but that worked?
Which phone was it and where did you buy it I know for a fact that any phone which has volte but not bought through 3 store will have the volte IMS service blocked because you need there version of Android firmware for it to work. I have had many arguments with 3 customer support over this.
the Volte and Wifi Settings are blocked by OP in their official firmware because they need the carrier to allow the settings on their phones. Some Asian imported phone manufacturers sometimes disobey them and allow it but this is not the norm.
Have you noticed that when you put in a sim from a major operator in the uk the internet/mms etc settings are usually auto configured?
three for example, configure their sims to block any 'non authorised' phone to auto download the required settings to enable wifi calling and volte.
This means that the only way of bypassing it (a bit like Sammy csc changing) is if there is a custom ROM available with the three settings pre loaded. EE are the only network that are essentially a 'slut' and allow their settings to (on the most part) be uploaded to any compatible phone.
I get 100 gig a month, unltd calls and text from Three for a ridiculously low £15 per month. I WILL NOT give that up !!!!
as much as i want an OP6 im sticking with a tried and tested Samsung S9 plus that to be frank is just as fast on the most part, and you can easily load three or whatever branded software to enable all the wifi calling and volte goodies.
O2 allow this also. The only real way to get volte working on a non 3 handset is when 3 release there factory stock images eventually and they can be flashed after rooting. Even with custom roms volte will not work for instance lineage etc although volte is implemented still doesnt work. I had bought a lenovo p2 a few years ago and volte did not work for a whole year untill 3 factory images were released and i rooted the phone and installed the 3 firmware then it started working. 3 are real scumbags in this regard.

all u need to get three volte working is essentially the ims settings, ive seen people being able to get three volte and wifi calling working on various grey imports. But agreed its a very convoluted process.
All one plus's use their own firmware, they dont have carrier versions like samsung and others ...
That is correct the only way oneplus would have volte settings is iff 3 sold oneplus on contract otherwise it is a difficult process. I would be very interested nevertheless iff someone in the future figured out a way to get volte working on a non 3 phone other than using there firmware. By the way i am not a oneplus owner but in fact i have a xiaomi mi6 but i am in the same boat ref volte.

Unfortunately, I was able to flash the H3G firmware onto my Italian source S8 and use both VoLTE and VoWiFi without ever speaking to Three, same applied to the unbranded S9 I got from CPW SIM free!

I have access to a OP5T and VoLTE and VoWiFi both worked out of the box!
My Pixel 2 - not a chance!
It's easy my dude, there are some bugs with it but hey you can't have both of the best world just yet.
Tutorial : Open Magisk - > Go to Downloads - > Search for VoEnabler - > Reboot - > Activate the VoWiFi and VoLTE in the settings. - > SUCCESS.
Bugs? Only bug I found is that every time someone calls you it will say Unknown (While on VoWiFi, haven't checked on VoLTE yet.)
Let me know how you get on
Three VoLTE working here too using Vo Enabler.
Sorry i am in the weird situation although im not a oneplus 6 owner. I have a xiaomi Mi6 and i used the module voenabler and now i can make calls over wifi but the enhanced Lte option in settings has vanished completely and in the 4636 settings the option for wifi calling became available but the volte option is now greyed out.
I have got VOWIFI working on 3 with pie, I upgraded to 9.0.0 then did this
Dialled *#800#
Went into OnePlus logkit
Went into Function Switch and checked VOWIFI and VOLTE then rebooted
The options now appear in SIM settings and you can turn them on or off.
When I installed 9.0.1 the Function switch options had been removed but as I had already turned them on the SIM options persisted On installing 9.0.2 the Function Switch settings had returned but with a dev test warning.
I have entered airplane mode, turned on WiFi then made and received a call.
The 3 IMS was automatically configured
And some screenshots
I was able to active vowifi but volte is not registering, I did notice that when I connect to WiFi a do a call and during the call I disconnect the WiFi volte start working but only on that call after the call finish it discomect and goes back to no volte. This is on three UK with Pie using the logkit.
@crazdgrunt99 does volte still works for you using the vo enabler?
Got Volte working with 3UK
I got Volte working in my OP6 with 3UK. I used the softwares mentioned here - https://forum.xda-developers.com/oneplus-5t/how-to/guide-volte-vowifi-german-carriers-t3817542
I only installed the softwares mentioned and used *#800# oneplus logkit to enable volte/vowifi options- after that I followed other method used by Jamal , guy who figured out these methods for OP6 (please take EFS backup before this procedure)
Open EFS explorer that is part of qpst software, select your phone , it will start loading directory and files-
Once the directory structure is loaded , go to following path - nv/item_files/modem/mmode
Open the attachment with this post. Delete all files that are same name as in the attachment from Mmode directory in EFS explorer. Note some files are not there. After deletion load the files from attachment to EFS explorer - load as item files - you can select all and load
Reboot phone and it should have Volte working.
Now that A10 is available for the OP6, I can confirm VoLTE working on both OB1 and the production version, at last. (no hacks required)
What about WiFi calling that works too

4G is technically LTE. The Xiaomi firmware doesn't seem to have an LTE icon, at least not that I have seen. 4G and 4G+ are LTE and LTE-A.

thanks for the info
After the *#*#86583#*#, try going into Mobile & Networks, and select your SIM card. There should be a VoLTE enabled option now. This option didn't show up for me until I did that and then I had to turn it on.
There's now a tiny VoLTE icon in the notification bar and when I'm on a call, it stays there.
Try code *#*#869434*#*# to disable VoWIFI check. And check if it working on T-Mobile.
I don't have Tmobile to check it.

No, VoWifi doesn't work on t mobile
What ROM's have people tried for WiFi Calling? Does the OP refer to T-Mobile in the UK/EU or USA? The Global Stable seems to have some less features compared to the Chinese Stable. I had Advanced Messaging working in the default text app when I was on Chinese Stable by doing nothing but it does not seem to work on the Global Stable.
got volte working on tmobile US just not wifi calling but its fine

Which ROM is your device using? I really want to flash my green one back to the Chinese Stable. Global Stable just isn't as good in my opinion.

Eu global the lastest one 10.2.2.0
Ever find a solution to this? I am on MIUI Global 10.3 (Stable) and am able to turn off Mobile data( T Mobile is my carrier in U.S.) and with my WiFi on the device i can still make and receive phone calls. In this configuration i obviously still see my WiFi symbol in the Notification bar as well as the VoLTE symbol. Don't know if this will help you at all, but it is some stuff i have noticed recently when i was trying to figure out why T-Mobile apps dont work on my Mi Mix 3.
With WiFi turned off and Mobile Data turned on i am able to make phone calls(obviously) with VoLTE and am able to see the LTE+ symbol in the Notification bar as well.
If i go to About Phone --> Tap "Internal Storage" 4 time(brings you to the Testing Menu) and looking into the Phone Info i see the following...
Set Preferred Network Type: LTE/TD-SCDMA/UMTS
Mobile Radio Power: On
VoLTE Provisioned: Off
Video Calling Provisioned: Off
WiFi Calling Provisioned: Off
EAB/Presence Provisioned: Off
When i bring this menu up on my previous phone(LG G7 ThinQ) i see that the Preferred Network type was different...so i changed my Mi Mix 3 just to match to see how it would change
My LG G7(without a SIM inserted) shows the following
Set Preferred Network Type: LTE/UMTS auto (PRL)
Mobile Radio Power: On
VoLTE Provisioned: On
Video Calling Provisioned: On
WiFi Calling Provisioned: On
EAB/Presence Provisioned: Off
Changing the network type on my Mi Mix 3 didnt do much, however when i changed it LTE/CDMA/UMTS auto(PRL) the VoLTE Provisioned and Video Calling Provisioned both switched to "On".
I dont quite understand this so for the most part i have just left it to match my LG's setting since i can change the network type back to LTE/UMTS auto(PRL) after and the settings stay set to "On"
Made a few test phone calls after with WiFi on and off, everything seems to work just fine regardless of what the phone displays.

Put the device in airplane mode, then turn on WiFi. Can you make calls? I can't! Turning on WiFi and enabling WiFi Calling doesn't mean the calls are going over WiFi. Especially if you are still seeing VoLTE or any time of mobile network connection.
Edit: Go down to the very bottom, hit more, hit IMS status, and see what it says.
Yeah I looked at the IMIS before, voice over wifi has always(I assume) said not unavailable

No access to the IMS settimgs is more than likely why we can't get it working. We cam't see the settings to even compare them to what they should be.
I am on MIUI Global 10.3 (Stable) / Chinese Device / T-Mobile Germany.
VoWiFi as well as VoLTE are working on my device, however you need root access to enable the VoWiFi profile.
Once it is working you will see the WiFi calling icon in the status bar.
I was following this guide to enable WiFi calling on the Mi Mix 3:
https://forum.xda-developers.com/poco-f1/how-to/guide-activate-vowifi-wlan-call-t3871263
I don't know if the mentioned profile will work in other countries as well but maybe someone with more insight can shed some light into this.
I remember that VoLTE was working out of the box, you just have to disable the carrier check with the USSD code to make it available in settings.
VoWiFi can be enabled via USSD code as well, however even after changing the setting to enabled and preferred WiFi calling it does not register without the profile change.
VoLTE: *#*#86583#*#*
VoWiFi: *#*#869434#*#*
I had to redo the profile change after each upgrade with TWRP, since the firmware partitions get updated as well.
I hope this will help. :fingers-crossed:
I have Mix 3 with U.S T-Mobile service. After disabling the VoWiFi check with *#*#869434#*#*, the option for WiFi calling check box appears under the T-Mobile SIM section, but WiFi calling is not working when tested under airplane mode with WiFi enabled.
Vowifi works fine on MTS (Russia). All you need:
1. Activate vowifi service from the operator
2. Disable service check by command: *#*#869434#*#*
3. Create folder into: /system_root/system/priv-app/MBNLoader
4. Copy into this folder APK: MBNLoader.apk (View attachment MBNLoader.apk
5. Give right privileges: -rw-r--r--
6. Reboot phone
7. Install from play market QuickshortcutMaker: https://play.google.com/store/apps/details?id=com.sika524.android.quickshortcut
8. Open it and go to tab apps
9. Find Modem Config
10. Open it (tap) and you will see a lot of MCFG Modem configs.
11. Try one by one to start vowifi working
12. Enjoy!

TELSTRA Australia Users - I have VoWiFi all of a sudden!!??

Cant remember what exactly what I did, but I followed guides here;
https://forum.xda-developers.com/oneplus-7-pro/help/force-enable-volte-vowifi-t3934227
&
https://forum.xda-developers.com/oneplus-7-pro/how-to/guide-activate-volte-vowifi-t4116051
and
The later being the most recent. Whats even more surprising I have previously heavily de-bloated this rom using xXx No Limits to the extent VoWiFI and LTE feature aren't even available (but I understand changes carry forward as they are saved to the EFI partition)
Anyways, going to dive into to see what exact setting I enabled and will post back.
Any other Telstra users notice they have VoWiFI this morning?
Edit: Updated with PDC Setting for Telstra Volte & VoWiFi :laugh::laugh::laugh::laugh:

Yea, so I know have VOLTE as well!! Really a nice surprise this morning because reception hasn't been the best at home. Anyways,
I have a GM1910 (Chinese ver of One Plus 7 Pro 256Gb / 12GB running OOS 9.5.13 GM21AA with xXx No Limits magisk rom + Kirisakura custom kernel.
I have all installation files backed up as well as some are not hosted by the ops anymore.
What I need to figure out are the specific change I made to the IMEI with the qpst programs... I don't think I did anything to major in the end there, it was months ago and didn't yield any affect.
Any Telstra users have VOLTE and VoWiFi without having done anything!?
I'll post later today my PDC settings

Updated post with req. PDC setting, can someone confirm if working on their end too?
No such luck on my end. I have the same model and have tried a few versions to no avail. I have had volte pop up before, but the moment I made a call it switched back to 3G. Have you confirmed them to be working? I need vowifi, i have no reception at home. Sick of facebook calling...

I just made an additional discovery, you also need to have "My Telstra" app installed as well just as a normal app and have run it at least once then reboot. Have you tried that?
Also, in you Sim settings you have VOLTE and WiFi calling enabled?
Volte and VoWiFi are working here, during call it he phone app will advise call is over vowifi
I'm SOL.
Got a HD1913 1+ 7T Pro.
Tried everything but cant get VoLTE or VoWIFI to work on Telstra.
Running Firmware 10.0.10.HD01AA
Have all the options enabled under Sim1 and through *#*#4636#*#* its all enabled.
Unfortunately no VoLTE sign or VoWIFI when calling. HD symbol works during calls, but thats about it.
Even have the Telstra App installed and full permissions.
UPDATE****
So i put the phone into aeroplane mode and enabled only wifi, tried to do a call and it failed, then BAMMM! VoWIFI enables itself and now I have VoWIFI enabled.
UPDATE 2****
VoLTE has enabled itself too. Looks like the trick for Telstra is to go into aeroplane mode, make a call with wifi enabled only, accept that it says called failed and it should enable VoWIFI and VoLTE.
Happy Days!!!
I'm also on Telstra (Boost mobile) and managed to get VoLTE and VoWIFI working on my OnePlus 7 (non-pro version).
I followed the guide exactly as described here: https://forum.xda-developers.com/oneplus-7-pro/how-to/guide-activate-volte-vowifi-t4116051
After I did all the steps, I rebooted and VOLTE didn't seem to work at first. But then I went into airplane mode and made a call with only Wifi enabled as kw0n2k suggested above. Then VoWIFI and VoLTE started working immediately.
When I was following the guide, the Logkit app preinstalled on my phone didn't have the VoLTE switches so I had to download the Logkit APK they recommended in the post.
For the VoLTE profile, I used "Telefonica_UK_Commercial" as mentioned in the post.

ADB question

Hello,
I was trying to find out how to add / force icons on status bar. Everything is just talking on how to hide them.
I am trying to add Wi-Fi calling and volte icons on the status bar. There is no option under display / icon manager to turn it on, like I have on 6T. Not sure if this is T-Mobile stupidity removing this or all 7T have same restriction. Please note wifi calling and volte are activated and working - confirmed. It is just icons that I am missing.
I tried using systemui tuner in it it shows that volte and vowifi icons are turned on. It seems that T-Mobile is blocking it and unfortunately this phone cannot be converted to international version.
Phone: Rooted OP7T Pro 5G McLaren (T-Mobile) (latest update).
So million dollar question is... Is there an option to force it with command through ADB, as mentioned phone is rooted.
Thank you guys.
think it's not possible
May you should switch to a custom rom.
