I have a RealMe X2 pro in the USA. I got my phone working by having root, plugging my phone in, going to adb and typing adb shell, setprop sys.usb.config diag,serial_cdev,rmnet,adb. then it kicked adb out of the shell. I typed adb shell, su, and this

(FW From a friend) Once you issued the "su" command check with "id" if you are root. It won't work unless you are root.

Once you issued the "setprop ..." command you can check with "getprop sys.usb.config" if it shows 'diag' in the result.

Then PDC should work. It's a little tricky to get working with the Qualcom drivers.

If successful, run "Advanced PDC Tool", click on device "down arrow" (should populate). DEACTIVATE SUB 0 & SUB 1 !!!

Then you can just pick from the list. Select the name & then click "Activate"? If it doesn't work, just deactivate and pick another one. Doesn't matter, you'll know. If it does work, You'll have to place a test call (what I did) if your phone doesn't show VoLTE connection in the status bar. Old Lineage 18.1 would show "VoLTE" in the status bar. New Lineage doesn't show that (for my device). Good luck!

So when you add multiple carrier mbn files with PDC tool, they will automatically enable when I insert a Sim for thwt carrier or I must use PDC tool to activate them?

Can I do this with Sony Xperia 1 ii with out root?
[Xiaomi Poco F1 Guides, News, & Discussion] ippo18:
hi!

On my OP Nord 5G I managed to make VoWifi working changing the congif with PDC. At each reboot, it goes back to my carrier config, which has Volte.

If I delete my original config, at reboot it goes back to Oversea commercial profile (which even doesn't have Volte).

Do I need to delete this "Oversea-Commercial_DS" to fix it?

Many thanks!

Do you know if this works on your latest crdroid rom? I am on O2 UK. Thanks Simon.
[Xiaomi Poco F1 Guides, News, & Discussion] saski4711:
Gave this another shot today with latest LOS16 and a fresh windows installation. Works lice a charm :highfive:

Thank you! :good:
[Xiaomi Poco F1 Guides, News, & Discussion] Flatric:
Works perfect with Mi Mix 2s and AOSIP Rom, thank you!

Edit: Are SMS supposed to work with VoWifi? If they are they are not working for me

Edit2: SMS are not supposed to work, so all good:)
[Xiaomi Poco F1 Guides, News, & Discussion] saski4711:
Receiving SMS in deed works on my Poco f1. Sending however doesn't. Something even more weird: After trying to send a SMS my VoWifi settings for my SIM slot got disabled again and I've lost VoWifi capability. Had to use PDC once more to (re)activate it.
[Xiaomi Poco F1 Guides, News, & Discussion] Flatric:
Hmm I couldn't test receiving SMS but also after trying to send a few SMS my VoWifi kept working luckily

In the latest official stable global version 10.2.2.0 vowifi work natively like volte

just type in call app to active it
[Xiaomi Poco F1 Guides, News, & Discussion] der_Kief:
activating the VoWiFi setting doesnt mean that VoWiFi is working !

Q: How to know if VoWiFi is working ?
A: Put phone in airplane mode and reactivate WiFi only. If you are able to make a call then VoWiFi is working.
[Xiaomi Poco F1 Guides, News, & Discussion] ogy_j:
Yes but in mine it work, i've the icon + i can make call from wifi

so it is working in the latest version without any tricks apart *#*#vowifi#*#*
[Xiaomi Poco F1 Guides, News, & Discussion] saski4711:
I have VoWIFI enabled on my Poco F1 with LOS16 and it definately works (no reception at all in my office but wifi calls are getting through). I have no VoWifi icon but I get a Wifi-Call message on my call screen. Switching to Airplane mode and reactivating WiFi strangely doesn't work. I get a message that I have to disable airplane mode. :confused:
[Xiaomi Poco F1 Guides, News, & Discussion] der_Kief:
there is no VoWiFi icon in custom ROMs ... only in MIUI

than VoWiFi definitively dont work ...
[Xiaomi Poco F1 Guides, News, & Discussion] saski4711:
Wel l beg to differ. I have crystal clear HD reception even with no cell signal at all. When I turn wifi off the call gets dropped right away. Maybe the failure to get it working in airplanemode has to do with LOS16 I don't know.
[Xiaomi Poco F1 Guides, News, & Discussion] zjaraniec:
I have used that method on Redmi Note 5, but I have problem. There is no profile which I need (Orange Poland), on german thread of that guide (android-hubo) I have found file mcfg_sw.mbn but after adding that into PDC there is still needed profile. Is anybody have other mcfg_sw.mbn which will pass ?
[Xiaomi Poco F1 Guides, News, & Discussion] faeArai:
So what's missing for VoWiFi? I've enabled VoLte for O2 and it's showing the symbol in notification menu. But it won't do voice over wi-fi. I was thinking, that it's the same setting/profile as in both cases phone will connect to a kind of advanced sip server of my provider.

I've stock and although I enabled the vowifi checkbox, there is no connection for me. Only volte is working so far.
[Xiaomi Poco F1 Guides, News, & Discussion] faeArai:
So I rooted my devices, got the drivers installed and when I connect my unlocked phone to my Windows 10 computer, I can see a qualcomm hs-usb device being connected. But when I start PDC as administrator, its empty and i can't see any entries nor can I activate the profile. What might be wrong?

edit: I totally missed that dropdown menu. could set active value for both sub0 and sub1 with DT_Greece. Unfortunatelly no VoWiFi on ASOP Ex

Edit 2. After second try and a newer PDC it works now even with airplane mode. Unfortunately there is no symbol to show VoWiFi. But hey at least it works.
[Xiaomi Poco F1 Guides, News, & Discussion] der_Kief:
if I'm not mistaken ... only MIUI shows that VoWiFi symbol
[Xiaomi Poco F1 Guides, News, & Discussion] faeArai:
Sony also has pretty small and nice icons for VoWiFi and VoLte.

[Xiaomi Poco F1 Guides, News, & Discussion] saski4711:
Same here. Apparently this doesn't work at all on the MIA1 - no matter what ROM you are running. :rolleyes:
[Xiaomi Poco F1 Guides, News, & Discussion] prorooter007:
For Indian users . There is probably only one provider called jio which provides vowifi but only through jiofi router.

I don't know if it works on A1 though. I have to try.

[Xiaomi Poco F1 Guides, News, & Discussion] rickyroma:
Has anyone tried activating other carrier settings within PDC as per this thread ?

[Xiaomi Poco F1 Guides, News, & Discussion] vcdwelt:
Ok, thanks.

So nothing special. Thought there is something to pay attention like some Samsung Models...

But another Question :)

Where is this setting stored, in EFS Partition as far i understand? And when will it go overwritten (Flashing new Rom, Factory Reset)?
[Xiaomi Poco F1 Guides, News, & Discussion] saski4711:
EFS does not get altered when flashing a custom ROM or doing a factory reset. With Stock ROMs that's a different story. But details on that are beyond my knowledge unfortunately. Maybe someone else can explain?
[Xiaomi Poco F1 Guides, News, & Discussion] vcdwelt:
Thank You so far.

My concern was, what will happen if i root my Phone enable VoWifi and remove root to get updates...
[Xiaomi Poco F1 Guides, News, & Discussion] melodystyle2003:
As a method looks that it works on 10.2.3 rooted poco, although calls via vowifi do not come through (maybe i am restricted by my providers).

[Xiaomi Poco F1 Guides, News, & Discussion] Madmonk33:
VoWIFI working on stock ROM locked bootloader with three network in UK after I got them to provision my sim for wi-fi calling. At first they said Pocophone f1 not compatible for wi-fi calling so I told them I will be moving to another network for my services and 15 minutes later I had wi-fi calling. Terrible I had to threaten to move company to get this service. Tested it and it works great.
[Xiaomi Poco F1 Guides, News, & Discussion] crok.bic:
I have exactly the same issue just like you - did you solve?

I would like to use PDC on my Redmi Note 4X (Mido)... .. . no luck yet.
[Xiaomi Poco F1 Guides, News, & Discussion] lankosher:
For me it worked the following way:

Download Terminal Emulator apk - MAGISK will grant it SU priviliges

Launch Terminal on your phone and type in:

su

setprop sys.usb.config diag,serial_cdev,rmnet,adb

Wait until the drivers get installed, check its status in "Device Manager" on your PC

Once the drivers have been loaded type in the code on your phone *#*#717717#*#*

Launch PDC and choose your device from drop down list.

Select appropriate profile and activate it.

That is it.

Great, this actually works!

I used DT_Greece in for Telekom Slovenia and Vowifi works just fine.

However I lose incoming caller ID - all numbers are unknown?!

Can somebody suggest sollution for this?

I have also tried few other profiles but none of them worked.

I am on MIUI 9.6.13.
[Xiaomi Poco F1 Guides, News, & Discussion] lankosher:
You can try choosing a different profile e.g. DT_Croatia, not really sure if there is any specific for Slovenia, I could not find any in entire list.

Alternatively you may try edit "overideconfig" file by adding below lines:

[SIPConfig:FeatureFlags]

*IsImsiNeededForContactHeader = 0

It can be accessed with EFS Explorer in QPST.

Once your phone has been connected, you search for a folder "efsprofiles"﻿ where the file "overrideconfig" is located.

Drag it to your local folder, edit with Notepad C++ and drag it back to EFS Explorer.

This should resolve the lack of caller ID
[Xiaomi Poco F1 Guides, News, & Discussion] franciz666777:
Thanks for the tip, but it didn't work.

Tried few other profiles - if Vowifi works, caller ID dissapears (ie Netherlands-Volte-Vodafone)

[Xiaomi Poco F1 Guides, News, & Discussion] boringgit:
Superstar!

Worked for me in the UK on Vodafone.

Stock Rom, no ADB manipulation, no root.

Make sure to enable in the My Vodafone App first though

In My Vodafone

Go to Services and extras > Calling options > Switch Wi-Fi Calling On

In the My Vodafone App

Go to My Products and Services > Manage Bars and Extras > Calling Options > Switch Wi-Fi Calling On

(It then can take 24 hours - be patient :) )

FYI - I had to type in the code twice, first time nothing happened (or I mistyped), second time it said "VOWIFI carrier check disabled" or similar...
[Xiaomi Poco F1 Guides, News, & Discussion] danbr:
Thank you, i put it onto DT_Greece and sure enough the wifi calling symbol appears. However, when i go to make a call it says mobile network not available and still when i go to *#*#4636#*#* it has vowifi and lte greyed out and on no. Am i doing something wrong?

Edit: So the phone receives calls over wifi calling but won't call out. Any ideas?

I read your link to connect mido as example, but sorry this is too hard for me, i don't want to take huge risks and mess up my redmi note 7 ^^
[Xiaomi Poco F1 Guides, News, & Discussion] crok.bic:
The logic is that you only have to install QCOMDiagMode.apk and Magisk for root because if PDC does not see the phone while you are 100% sure that the diag mode is activated then the script part of the diag mode in the ROM is fsckd up and the app can help you - but if you consider this whole thread (or steps I described) to be a huge risk I honestly advise you not to even start the process.
[Xiaomi Poco F1 Guides, News, & Discussion] baloo247:
I can confirm that if you have BT Mobile use DT Greece and it works fine. I had to remove the EE Commercial one that was defaulting to, as everytime I rebooted it took precedence. I can now make and receive VoWIFI calls. I had to set DT Greece for Sub0 only.

Hey, I'm on EE. I've got the VO-LTE on and WiFi calling is enabled but it does not seem to work. I also have the EE commercial one as active. Do you suggest deleting EE and enable DT Greece? I've got a mix 2 s
[Xiaomi Poco F1 Guides, News, & Discussion] rickyroma:
I'm on EE, Pocophone F1. It definitely works to enable DT Greece and deactivate EE commercial. If you want it to persist over reboots then you will have to delete the EE_commercial profile as it will revert to this otherwise. If you just wanted to test without destroying anything, just activate DT greece. I would back up your EFS partition before deleting profiles just in case.
[Xiaomi Poco F1 Guides, News, & Discussion] XDRdaniel:
It works! Thank you!

Thanks for your guide! Is dual WiFi calling possible?
[Xiaomi Poco F1 Guides, News, & Discussion] TheRealBeast:
Very late reply to your post, hopefully you are still around (or somebody with experience with Three UK).

Thanks for sharing that info. Good to hear you managed to get it working. Is it still working now? Recently moved house and the reception is very bad here so hoping this might solve the issue.

Don't fancy rooting my phone if I don't have to. Used *#*#869434#*#* to make sure the phone is checking for vowifi and it is. Am I right in thinking it is therefore simply a case of Three not having activated this on my account yet?

Many thanks!
[Xiaomi Poco F1 Guides, News, & Discussion] Madmonk33:
Hi it could be that three have not provisioned you sim or you have not went in to SIM card settings and toggled WiFi calling on you phone. When you dialled *#*#869434#*# did you get the message "vowifi carrier cheklck disabled" if so and you have toggled WiFi calling in SIM card settings then you're SIM needs provisioned.

Hope this helps you.
[Xiaomi Poco F1 Guides, News, & Discussion] TheRealBeast:
Well I never :)

There was me thinking for VoWiFi to work I should have it set to 'vowifi carrier check was

enabled

' but clearly that was a wrong assumption.

After going for 'disabled' the option is there :) Been testing for a bit and it seems to work.

None of Xiaomi device VoWiFi supported by Telekom. In my case VoWiFi activated at service provider side (Telekom) and on the device as well but VoWiFi still doesn't work in practice.
