Hi, are you sure that your Mate 30 Pro chinese has VoLTE service callings ??? I received an email from official care Chinese Huawei and they said to me this:

Thank you for contacting us.

Regarding the situation mentioned by you,We are so sorry for the bad experience.Maybe the equipment you purchased is a domestic version, there may be some functions that can not be used properly overseas.We suggest that you can consult the local dealer to purchase an overseas version for use.Please understand the inconvenience!

Best Regards,

Huawei Customer Service

Have you then been able to enable this service on your Mate 30 Pro chinese? Waiting for my network provider to enable the Mate 30 Pro for me to use the VoLTE service, do I just have to do what you put in the YouTube video?

That is, I just have to create the parameter "hw_networkmode_preference" and give it the value 9,3,2,1,11?

Do I also need to create the parameter "hw_networkmode_gstyle" that I don't have?

Are these values in case I have selected the 5G / 4G / 3G / 2G mode on the Huawei, or should I only carry it 4G / 3G / 2G? Because 4G value only I don't have it.

[EDIT]

This is the last email I received from Huawei care service fom China:

Thank you for contacting us.

Regarding the situation mentioned by you,we are so sorry.When 5G is enabled, VoLTE is activated by default and therefore the VoLTE HD calls menu is hidden. This feature requires the local Mobile telecom carriers support. For the domestic version of mobile phone to go overseas, the phone needs to use overseas SIM card and support overseas 4G band to use VoLTE. The volte of a small number of overseas Mobile telecom carriers is not open. The specific usage is subject to the local Mobile telecom carrier.

That is that my Mate 30 Pro 5G LIO-AN00 VoLTE callings service menu is hidden when I use 5G network ... but it works ????
[Huawei Mate 30 Pro Questions & Answers] Sathelp:
Yes, mine is working on EE in the UK. I have the status bar symbol, I am able to turn it on and off from the menu. I done far more than adding one line if text! Re-read my post on what I did with screenshots.

It may be that your network provider has not authorised it or it is not available where you are, if this is the case, then you need to ensure you can use it before trying to get it.
[Huawei Mate 30 Pro Questions & Answers] luisvalino:
Hi [MENTION=711033]Sathelp[/MENTION]

Once my Spanish network provider authorizes VoLTE to Mate 30 Pro, can I use your method ?.

There is something in your method that is not clear to me: I have a 5G / 4G / 3G / 2G network and a 4G / 3G / 2G network. Which one do I choose? Having 5G, is there any more value than 9,3,2,1,11?

My Mate 30 Pro is LIO-AN00 chinese version.

Thank you.
[Huawei Mate 30 Pro Questions & Answers] Sathelp:
I use sim 2 as I have my EE sim there and that's the one that has VoLTE turned on.
[Huawei Mate 30 Pro Questions & Answers] luisvalino:
But I only use 1 sim in sim1 slot, I don't use sim2 slot because I haven't two sim cards, I have the NM Huawei card in sim2 slot.

Also, reading your method I think there I have to use ADB in the PC console, really? And that for me very difficult, I thought that your method was easier but it is not.
[Huawei Mate 30 Pro Questions & Answers] luisvalino:
Also, I asked you if I had to choose the option 5G/4G/3G/2G or 4G/3G/2G in the networks that I have, but you haven't answered this either because in the tutorial I don't see this coming.

That's why I ask these questions, because I also don't know how to handle ADB on a PC console and tried to get someone like you to explain it easily because I am NOT an expert and I try to get help from you, nothing else.

I help a lot in this forum to the people and in others, and I explain things clearly step by step, always I do but I never received the same helpness.
[Huawei Mate 30 Pro Questions & Answers] luisvalino:
I suppose you have learned to read, write, add, subtract, program ... right? Or did you learn by yourself and make us suppose that all of us who are here and ask for your help are not very smart and are born with everything already learned?

If I ask you something that you know and you only offer me an empty answer without any details, well, it would not help. Learn a little from people like me, that we all have to learn from someone, maybe I from you in programming, but I'm sure you learned from someone, right, or am I wrong?
[Huawei Mate 30 Pro Questions & Answers] Sathelp:
There are many adb instructions and read ups on here and the internet. It basically uses a command prompt from a connected pc to input to your phone . To start with, you need to enable developer on your phone and set usb debugging on. Once there, use your command line instruction to change folder to your adb folder, once there you need to type adb devices to ensure your phone is connected and authorized. Then type the lines in the post.

Go and read up, down load the drivers and adb commands and have a go. You can brick your phone, Sono warranty from me, if your not sure, don't do it

Hi [MENTION=711033]Sathelp[/MENTION]

At your post -> https://xdaforums.com/showpost.php?p=81558047&postcount=47 when you say:

NOTE:

You may be asked by the app for permissions to be changed by using an adb command It may require you to run "adb shell pm grant by4a.setedit22 android.permission.WRITE_SECURE_SETTINGS" on a computer. If so, just follow the instructions from the XDA thread discussing the Settings database editor app if you are in doubt about using ADB commands.

-That is after reboot my phone app ask me for use that adb command, or app ask maybe ask for use that adb coomand before reboot the phone ???

-When you say "may be asked" is sure or maybe ... ??? that is that app could not ask for add this adb code ???

-I've read something about adding adb commands and it doesn't seem very difficult. Is it just adding that command there and nothing else?

-Will it cause any issues for the Mate 30 Pro? Because it was very difficult for me to set Google services at the end of 2019 and they work very fine and I would not want to factory reset the device and lose them.

-Settings Database Editor app could be uninstalled after this or need to keep installed on my phone ??
[Huawei Mate 30 Pro Questions & Answers] Sathelp:
It depends on whether you already have that permission. If you cannot make change now, then you must enter the command via adb to allow set edit to add the line.
[Huawei Mate 30 Pro Questions & Answers] luisvalino:
And just I change the wfc_ims_enabled_0 value or create into the phone, adb command, reboot and finish?

VoLTE menu options It doesn't display on my Mate 30 Pro and WiFi calls doesn't too.

For further official Huawei updates, have I repeat this process ??
[Huawei Mate 30 Pro Questions & Answers] Sathelp:
No, once done, that's it. Just have to wait for your service provider now to get it enabled
[Huawei Mate 30 Pro Questions & Answers] luisvalino:
Ok thank you!
[Huawei Mate 30 Pro Questions & Answers] luisvalino:
Could I uninstall Settings Database Editor app after that?
[Huawei Mate 30 Pro Questions & Answers] Sathelp:
Yes, its not needed after
[Huawei Mate 30 Pro Questions & Answers] luisvalino:
One last question, do I have to have the phone connected to the PC in the whole process to run the adb command or does the Settings Database app run first, and then connect the phone to the PC?
[Huawei Mate 30 Pro Questions & Answers] Sathelp:
You only need to connect to the pc while you add the line of text to set using adb. Once added, you can disconect. It is only to set the permission that allows set edit to add the extra lines, that's all.
[Huawei Mate 30 Pro Questions & Answers] luisvalino:
hi [MENTION=711033]Sathelp[/MENTION]

I opened "Settings Database Editor" app.

The app displays:

This device ---- System Table

When I change System Table to Global Table according with your process and I try to add a new setting it appears this message:

"SetEdit does not currently support editng this table.

pm grant by4a.setedit22 android.permission... etc. and I executed right adb command permission and the app let me add a new setting at Global Table without any problem :)

Then:

I added wfc_ims_enabled_0 with value "1"

I added wfc_ims_enabled_1 with value "1"

I reboot the Mate 30 Pro but VoLTE icon doesn't appears.

I make a call but changes from 4G to 3G.

Then in Global Table I added volte_vt_enabled with value "1"

I reboot the phone but nothing, the phone keeps 4G+ and when I make a call change from 4G to 3G.

Something wrong by me??

[Huawei Mate 30 Pro Questions & Answers] Sathelp:
Did you add the key exactly as this?

Then:

I added wfc_ims_enabled_0 with value "1"

I added *wfc_ims_enabled_1* with value "1"

I reboot the Mate 30 Pro but VoLTE icon doesn't appears.

With the *s?

I have attached my full instructions again to this post. Go through, double check. If you are sure everything is right, then it must be down to your network or provider.

[MENTION=711033]Sathelp[/MENTION]

Where I have to write the symbol * ???

Then, how is it?

*wfc_ims_enabled_1* -> right

wfc_ims_enabled_1 -> wrong

Could you help me, please ?? Thank you very much!
[Huawei Mate 30 Pro Questions & Answers] Sathelp:
wfc_ims_enabled_1, right. Look at the picture attached to my last post. It may have been a translation in to email but there are no *s in the commands. The email xda sent me showed you adding *s to the second line.
[Huawei Mate 30 Pro Questions & Answers] luisvalino:
That means that I did it right, really ???

Then, what happens ???

Is it a failure from my Network Provider ???

Do I leave the settings on the Mate 30 Pro as is in your process even if they do not work for the moment?
[Huawei Mate 30 Pro Questions & Answers] Sathelp:
It is up to you, the settings will not hurt. Huawei has said that they may not add the settings as China doesn't use it. At least you will be ready when and if your provider does.
[Huawei Mate 30 Pro Questions & Answers] luisvalino:
Ok, thanks !!

Hi again [MENTION=711033]Sathelp[/MENTION]

I did this:

To get a voice over WIFI (VoWIFI) shortcut I used this thread on XDA.

https://xdaforums.com/mate-20-pro/how-to/how-to-activate-wifi-calling-mate-20-t3922060/amp/

I installed Action Launcher and I could select WLAN Callings with a small icon like yours.

After that I would like to uninstall Action Launcher because I don't use it.

How can I manage that WLAN Callings icon to place at the Mate 30 Pro desktop ???
[Huawei Mate 30 Pro Questions & Answers] luisvalino:
[MENTION=711033]Sathelp[/MENTION]

I saw that in order to enable WiFi callings at Action Launcher app there is a key called: .settingsWiFicallings

Is it possible to enable by using Settings Database Editor app ??? Where is it if it possible ??

I have this feature but I think is hidden on myy Mate 30 Pro LIO-AN00.

Yes, there is. Everything I did is on my original thread and in the image I attached. Please read or translate the original.

And of course, by nature, Voice over LTE is only available on 4Gs data encapsulation. So no 4G, no VoLTE.
[Huawei Mate 30 Pro Questions & Answers] luisvalino:
Ok, I can do it but ... can I uninstall Active Launcher after that?

How can I place the WiFi calling icon from Active Launcher to the Mate 30 Pro desktop ??? ... or if I enable WiFi callings from Active Launcher, then this feature is enabled even I uninstall Active Launcher after that ??

Anyway:

wfc_ims_enabled_0 with value "1"

wfc_ims_enabled_1 with value "1"

volte_vt_enabled with value "1"

What is value =1 ?? What is the difference between value 1 and 0 ???

I'm trying why are VoLTE callings working at your Mate 30 Pro chinese LIO-AN00 and why not at mine if we have the same phone and I did the same process as you described ...
[Huawei Mate 30 Pro Questions & Answers] Sathelp:
Sim 1 = 0, SIM2=1.

You are using a different opperator, different country, different areas mast and equipment. There are many reasons why. I cannot explain, I have only showed you how to enable. Good luck my friend but I can't help you much more.
[Huawei Mate 30 Pro Questions & Answers] luisvalino:
I asked you about this value in red colour:

wfc_ims_enabled_0 "1"

wfc_ims_enabled_1 "1"

What is 1 ??? and if the value would be 0 ??

wfc_ims_enabled_0 "0"

wfc_ims_enabled_1 "0"

Hi [MENTION=711033]Sathelp[/MENTION]

There is a key that I found it.

I know what can I do in order to make Mate 30 Pro menu show the icon to switch on VoLTE button into its menu options:

Just I have to change this line using Settings Database Editor:

At "ANDROID PROPERTIES TABLE" change ro.config.hw_volte_dyn=true to ro.config.hw_volte_dyn=false.

But I can't. Why?. I attach you a screenshot. And using adb comand can't too.

I think this setting is in the build prop file. You need root access if it is. Mine is as below and mine works wirhout changing tbis setting.
[Huawei Mate 30 Pro Questions & Answers] luisvalino:
It's a pity because it is a line that I would like to change, and if it is blocked to use the Settings Database Editor app, it may be because of the root.

I don't think anyone at XDA can tell me how I could access this line to modify it, right? ... :(
[Huawei Mate 30 Pro Questions & Answers] Sathelp:
No, there is no root as you can't unlock the bootloader.
[Huawei Mate 30 Pro Questions & Answers] luisvalino:
Is there someone from XDA development who can give a clue how to change this parameter ro.config.hw_volte_dyn from "true" to "false"at Huawei's Android Properties table? Or maybe Huawei should release a small update by OTA adding this setting?

EDIT: I forgot another needed command -> "ro.config.hw_volte_show_switch" "true". And that's all !!! :)

So this is because the bad VoLTE support Huawei offers. Your best option is join the Beta program for EMUI 11 and report the issue via the Beta app. They have an specific option for report that VoLTE doesnt work with an specific operator. I have the same issue but with a Mate 20 and t-mobile USA.
[Huawei Mate 30 Pro Questions & Answers] luisvalino:
I can´t join it because Beta program for EMUI 11 is closed for Chines devices as my Mate 30 Pro 5G LIO-AN00.
[Huawei Mate 30 Pro Questions & Answers] luisvalino:
I think I'm going to give up and take this "battle" for lost.

According to Huawei, when I reported to the Chinese technical service some months ago they told me that my Mate 30 Pro 5G has the VoLTE call service enabled although it is hidden at the menu, and that it must be my network provider in Spain that they have to provide me with the service.

My Spanish network provider - Movistar - tells me that the service is active, and that Huawei has to provide me with the software needed so that the service can be enabled.

Summary: I have nothing .... :crying: :crying: :crying: :crying: :crying:

Did you have to do anything special to get the VoLTE service enabled on your Chinese Mate 30 Pro?

In my case I am frustrated ... !!! :( :( :crying: :crying: :crying:
[Huawei Mate 30 Pro Questions & Answers] luisvalino:
Neither Huawei nor my network provider Movistar give me any solution. It's unbelievable !!!!!
[Huawei Mate 30 Pro Questions & Answers] DonVolVoda:
This is a common issue with Chinese devices being used outside of china. it all depends on the 4g/5g bands the phone uses and which ones your network support. 4g/5g on vodafone UK/IT only supports volte or vowifi if it is a device that they officially sell or if the manufacture supports the networks carrier settings this is most likely the case movistar too. as this is a Chinese variant and wasn't officially sold with carriers, support will be limited if not no support will be given as it isnt the global/international model.. volte doesnt work on vodafone uk with the chinese model but it does with EE uk so it is most likely down to the network not being able to support the device not huawei
[Huawei Mate 30 Pro Questions & Answers] luisvalino:
In Spain, this network provider carrier - Movistar - has approved the P30, P30 Pro, Mate 20, Mate 20 Pro, and P40 models to use its VoLTE network ... but the Mate 30 Pro does not.

It is something that I do not understand, it may be that I do not understand some technical parameter ...
[Huawei Mate 30 Pro Questions & Answers] DonVolVoda:
Did Movistar sell the mate 30 pro? As far as I'm aware with the company I work for they only support devices 1) if they sell them. 2) if it is the global variant/EU/international. No as we both use the Chinese model it could be 2 different things. 1) the Chinese model network bands don't match what the network uses. 2) the Chinese model firmware will show the toggle when a compatible network sim is inserted. This is what I was told when I contacted OnePlus support with one of their devices from China in the past. Different brands I know but same bands and country origin
[Huawei Mate 30 Pro Questions & Answers] luisvalino:
1) I think Movistar don't sell Mate 30 Pro device.

2) The only matter that could be is if my nano sim card I have it from 2018 is not compatible with the VoLTE service, although I can use 4G and 4G + networks.

I don't know if I would have to change the nano sim card because my Mate 30 Pro 5G don't show me the toggle to switch on VoLTE calls.

[MENTION=3645917]luisvalino[/MENTION] My mate 30 pro Chinese model doesn't show the volte toggle with a Vodafone UK sim in, but my p30 pro direct from Vodafone UK does show the volte toggle, so like I said it'll most likely be down to the network and variant device not supporting eachother. I know on some phones if you dial *#*#4636#*#* I believe you can enable volte calling their but Huawei doesn't allow the code to work

---------- Post added at 11:01 PM ---------- Previous post was at 10:59 PM ----------

This still wouldn't show the toggle on the phone, ive had both my 2 Vodafone UK Sims for about 5 years and volte was available on all my past devices
[Huawei Mate 30 Pro Questions & Answers] samvel2001:
Hi I have Mate 30 pro 5g chinese version with chinese rom and also have p30 pro VOG L-29 I had same issues as you guys had on both phones. long research and test brought me to a conclusion.

1) Both phones are capable to do a Volte calls and the future is hidden (HD voice toggle). Depending carrier and your phone firmware version and region.

2) carrier have to have Volte option

3) carrier have to activate that (4G LTE, VoLTE and Wifi calling (provision your phone on their end) I am on AT&T and those phones are showing as an unknown phones on their system ( I think T-mobile is not much different). So here what you should do, call Your carrier customer service tech department ask them to provision your phone for above mentioned services. They will ask your IMEI if it's not there already and that's the issue, your IMEI is for unknown phone for them so their system will not allow you to use the full services, ask them to change your IMEI on their system and put a dummy one ( believe me if you get a knowledgeable representative they will know what you are talking about) . After they done it ask them to add/activate Volte and Wifi calling.

Now the most important thing after this is done don't put your sim to any other phone or sim tray 2 this will reset the IMEI number on carrier side and you have to start it over.

4) use the Setedit app to activate Volte on your phone and unhide the volte ( HD Voice) button on your phone( the process is described in a few XDA forums) After you done and reboot your phone you should have Volte icon on top left corner BUT!!!

5) some of you might never see it there even though you will have your Volte activated. Why ? Don't know, probably firmware / carrier communication issue.

To check if you have Volte activated while the volte icon is missing from status bar you need to force your phone to be on LTE data only and make a call, if you will be able to do so, than you are calling using Volte even though the icon is not in your status bar.

6) here is another issue adding "11" to the list of Preferred networks "11,9,3,2,1" ( "11" stands for LTE option only) might not bring that menu option to your phone settings. ( this is exactly my case ) so what I did instead of "11,9,3,2,1" I just change the value to "-1" which opened the full menu of preferred network and there you can choose LTE only option.

7 ) after you get to this point just make a regular call if you are on LTE only network and you are able to make a call than you are using Volte. Even though the "VoLTE" icon is missing from your status bar.

8) by the way I just got the Xiaomi Mi 11 ultra Chinese version, unlocked bootloader flashed EU stable rom and the Volte menu was missing as well. The solution was to get into hidden menu *#*#4636#*#* and change it from there, there are also special codes to activate the volte and wifi calling using the same method. It's easy on Xiaomi phones, but unfortunately Huawei is blocking all those menu options I think starting from EMUI 9.1 and up.
