G930FD - Dual SIM - VoLTE Support

Hi All,
I've seen many threads asking this question but doesn't answer it to my situation. I'm using this phone in Sri Lanka and my carrier recently launched VoLTE. I called up my carrier and got them to activate VoLTE for my SIM and so far I've not been able to make use of this.
The other threads talks about a setting either under Phone -> Settings or Settings -> Mobile Networks which is not there in my case.
Does this mean that the ROM/CSC that I have doesn't support VoLTE (I'm using the original ROM)?
Regards,
Asanka

In my S7 Dual Sim there is a Quick Toggle for VoLTE; Its there where you can turn on/off wifi, mobile data, bluetooth etc

VoLTE & VoWiFi working
Let's revive this thread.
I have a Galaxy S7 Duos (G930FD) which originally came with Kenya (AFR) firmware. After reading several threads, I replaced the firmware, using Odin, with the Indian (INS), but VoLTE still didn't show up. After verifing if the provider has enabled VoLTE on the SIM card in a Huawei P Smart an everything was functional (VoLTE and VoWiFi), making sure that the SIM card is in slot 1, I decided to re-write the Romanian open firmware (ROM).
And surprise ... Wi-Fi calling (under Connections) and 4G call (under Connections >> Mobile Networks ) are active and working.

Dear Nica,
I've been dying to get my S7 duos to work with volte and wifi calling features.
I've downloaded and installed over 20 different firmware versions and am unable to get it to work.
I can't locate Romanian firmware for 930fd model and was hoping that you can point me right direction please.
Would you please be able to help me?
Many thanks
Michal.

Michal, the G930F firmware works absolutely the same, you can flash it without reservations.
Here is the link for the latest Romanian firmware: https://www.sammobile.com/samsung/galaxy-s7/firmware/SM-G930F/ROM/download/G930FXXS6ESI4/295333/

Working on SM-G930FD with Mint Mobile USA
Hi there,
I thought that I would share my findings. I got volte working on G930FD. The setting comes up under Connections --> Mobile Networks --> VoLTE calls. I have tested it with calls and LTE Discovery app to make sure that I am not dropping back down to 3g/H+/etc... The calls are so much better for me. I am hard of hearing, so it really helped me. I will list how I did it below.
1. Download this firmware. https://www.sammobile.com/samsung/ga...S8ETC3/327944/
2. Use Odin v3.14.4 to flash BL, AP, CP, CSC ( I used CSC not HOME CSC)
3. Boot phone and enable developer mode (not sure if necessary, but this is the way I did it)
4. Reboot to download mode and flash TWRP (uncheck auto reboot)
5. Immediately after flash, reboot to recovery (Power, Volume down, Home to reboot, then Power, Volume up, Home to enter TWRP)
6. Swipe to allow modifications
7. Wipe--> Advanced Wipe --> Select Data --> Repair or Change File System --> Change File System --> EXT2 --> go back --> and then EXT 4 --> back all the way to main screen.
8. Install --> latest version of Magisk
9. Install --> CSCSelection_V3.0.0.zip https://forum.xda-developers.com/s7-...on-30-t3392957
10. Aroma --> Select XXA (Multi USA) --> Select XAA (Unbranded)
11. Reboot and wait to boot (Takes a few minutes)
12. Check in Connections --> Mobile Networks --> VoLTE Calls
That's it. Good luck!!
Oh yeah, Wifi calling is in the dialer app under settings, but I have had no luck with it, even though Mint Mobile supports it.

Convert H990DS AME to AU and get VOLTE (Root)

Hi there,
First, my apologies for my English ( I am not English native speaker) anyhow,
Today I managed to change my LG V20 H990DS AME ( Middle east ) to AU (Australia).
And one of the bounces I got is VoLte icon (Still didn't confirm if it is actually working)
The procedure doesn't require to flash a new rom, all what you need to do is the following:
- go to the root and find the folder /CUST (Use any root explorer)
- Open "open_path_mapping.cfg" and "op_list.cfg"
- You will see AU and AME have unique values ( in my case 57 for AU and 71 for AME).
- in both files write AU value for AME and vice versa.
- do factory reset ( all AU APKs and frameworks will be installed automaticly instead of AME stuff).
- once your mobile opened, in initialization wizard, Australia will be the default country.
- You will find the VoLte in the hidden tiles.
I am still exploring new changes.
Wish you all the luck.
Regards...
Note:
- This is experimental procedure, do it on your own responsibility.
- You can backup all your apps and files using LG backup, and you can restore them once the procedure is done.
- Same procedure can be done to all LG V20 phones

Wouldn't it have been easier using KDZWriter?

This is only sn alternative way of doing it.
Moreover, KDZWriter didn't work in my case.

why do you need volte in middle east anyway ?

I don't understand the reason for this question, but the answer, because most of the mobile networks here support VoLTE.
H990DS for GCC doesn't support VoLTE.

yeah i know they support ... but what is the actual advantage ... i dont see it sorry
if you know what kind of applications for this volte service let me know

I assume that the OP is living in India, and an user of Reliance Jio. In case you don't know, that particular Indian carrier only has 4G bands, so if your phone doesn't support VoLTE, you won't be able to make calls at all on that carrier.....
Not without Jio's app I guess. But everyone seem to hate it.

I dunno, cost-cutting I guess since Jio has some of the cheapest plan in Inida. You're welcome though.

Did it work for you?

Yes, it is required to do a factory resit, as e.g. some of AME apps are different than AU apps and those apps will be installed during first run after device format.
In your case the information only will be cganged, but not the apps as well.

TO be hones I am not sure, please check yourself if formatting "Storage" partition is the one. Of course all your data will be deleted. So, in all cases back up all partitions using TWRIP and move your data to external io external flash before proceeding.
You may also use LG backup, to back up all apps and their data, so after formatting "Storage" you will be able to restore all apps and their data.
Please do a little search about this procedure.

Ok. Are you able to see the options in the call setting to enable advanced calling /Volte?

VoLte is not there, I found it only in the main sliding menu in the main screen.
https://ibb.co/jx6rFo

Ok. Sometime back I also managed to enable the hidden menu options (ims)with lots of XML edits in cust folder and a factory reset. But volte never connected. Also the options were not visible in call settings menu. I had to stop testing as this was my main device. Need to test more but the factory rest is keeping me from doing it.
Would you know any region which has VOLTE enabled by default for global carriers? I could try flashing the cus partition and see. Mine is sea. Only has official VOLTE enabled for SG and TW carriers.

Android P VOLTE activate/settings ims file location root

Hi I own a pixel 2 xl. I live in Austria. My provider startet the volte support, but just for some samsung mobiles. I read that just phones worked who are bought directly from the provider with a branding. I talked with the support and the activated the volte for my telephone number. But when I look into the hidden menu *# *#4636# *# * then the volte is grayed out. It´s not possible to switch the settings on. A reboot of the phone doesn´t help.
I read in an German forum that someone changed the ims file from a unsupported samsung phone and activate the volte at the unsupported phone.
Where is this ims file located in android p? I know root is necessary to access this config files. Or is there an other workaround the activate the volte on pixel? (I read that for the one plus mobiles exists a workaround with the oxygenos)

Magisk module need help testing for China and Korea users.

The firmware does not contain carrier files for China and Korea carriers.
I made a magisk module that installs these carrier files systemlessly.
I don't live in China or Korea so I have no way to test this.
If you're living in China or Korea, please help me test the module to see if it works.
Thanks.

Hi swangjang, thank you for sharing your module! I used QPST to replace the modified xml files to enable 5G, and now I installed your module. The 5G runs well, but I can't tell if it is enabled by your module.
For VoLTE, the switcher appeared in the option, but it dosen't work. When I made a phone call, the network drop to 3G. (My carrier is China unicom)

Thank you for testing.
I think due to dm-verity, the module files don't actually get placed in the system. I'll need to wait until we get TWRP to disable verity.
Can you try and change sim cards to force the phone to reload the mbn file?

I plan to install a custom rom (custom roms don't have dm-verity) in the weekend and see if the module works on there. As long as dm-verity is enabled, I don't think any /system modifcation by magisk will work.

Hi, I live in south korea and I have UK version of Pixel 5(GTT9Q).
I'll try this module tonight and see if it works.
May I ask you where did you get mbn files for korean carrier? In my experience, KT and LGU need some efs modification especially for google pixel series, so directly injecting mbn from other device won't work well.

I got the mbn files from Xiaomi Redmi K30. The K30 uses the same chipset as Pixel 5.

Just tested module in south korea, but it doesn't works.
It seems that magisk module is doing it's job. I run root explorer and confirmed that mbm_sw.txt and other additonal korea and china mbn successfully loaded.
But when I run efs explorer, Banner shows "SW_DEFAULT" instead of "LGU".
Maybe Pixel 5 can't load LGU mbn because of some other reason.

Under section 3. part (4), "VoLTE calls can be made only by registering OMD (Open Model Device) as a VoLTE capable model name with each mobile operator".
Also, after installing the module, maybe reboot the device once?

Hi, I changed the SIM card of another carrier but the 5G is still enabled, even after I installed magisk completely and restore the original files with QPST, the 5G is still there...

Hi, I made more variations of the module using different mbn files for Korean carriers. Could you please them one at a time. It would be greatly appreciated.

I tried this with korean LGU, SKT simcard, but efs explorer shows SW_DEFAULT or Wildcard banner randomly.
I did sim tray out and in several times, and did WI-FI, Mobile Bluetooth reset on android settings-system menu.
And I also tried Taiwanese Chunghwa Telecom sim card which i got during taiwan travel, (Chunghwa Telecom is one of supported carrier for pixel 5) And It reports CHT banner correctly.
I don't know why, but it seems that pixel 5 refuses to load korean mbns for some reason.

Yes, I tried all of 6 mbns, but no luck. All recognized as SW_DEFAULT or Wildcard banner.
I'm trying to figure out why only pixel rejects those mbns. Maybe there's some hidden policy to reject unsupported country's sim?

I don't think there would be something that will reject it. Other people reported they got VoLTE working for their 'unofficial' carrier.

Question Enable Jio VoLTE and VoWifi on Xperia 5 III

Hi,
I need help enabling the VoLTE and VoWifi on my Xperia 5 III (XQ-BQ72 TW variant). So far, I have seen too many threads online and none of it seem to be working:
1. Flash different Region's firmware (tried 9 different regions from XperiFirm) but none work in enabling VoLTE
2. Try putting the sim into a different phone that has VoLTE working in my country (India), enabled VoLTE there, placed a call and then put it back in Xperia. Does Not work either! (Lame)
After trying so much flashing, I am coming to an end where I am about to give up my hopes that VoLTE will ever work in my device in India. I see a few members on XDA that either have a 1 III or 5 III with working VoLTE on different carriers but I don't know how they made it work for them. I am seeking some expertise here and hoping someone can help me enable this on my phone so that this doesn't become a paperweight for me. Appreciate any help/guidance in advance.

Can carrier you using not support VoLTE for Xperia 5 III,
I checked firmware off BQ72, but I not see firmware for India Market

Yes, coz Sony has officially left this market years ago, but there are many phones of their 1 and 5 series that do support VoLTE for Indian carriers. Not sure how those users end up with VoLTE (probably through upgrading their modem firmware or something). I need some help in enabling VoLTE somehow as I am reading it is doable but I am just not aware how I can for Jio.

I was able to download Xiaomi 11T Pro (as both these phones have 888) and extracted 2 .mbn files (one of Reliance and other of Airtel). Anyone who can try to add these to the Sony's .sin modem files as I do not have the expertise. That way we can try to flash this to our phone and see if it works. @htcmage is that something you are an expert with? I read many of your forum articles but was unclear on many things on how I can enable this on my xperia 5 III. I am seeking help from experts so that we can also have VoLTE in our region and would appreciate anyone's help with this.
Not sure if these files help. (Kindly rename the extension from .zip to .mbn)

I'd be surprised if someone needs to pay here since this is a community forum and people help out of their kindness in general here.
Would love to know the steps to enable this on my Xperia 5 III if you know how to. Please do share and enlighten us.

If anyone is still looking for enabling Jio on their 5 III, here is the complete guide that can help you to get this enabled. Make sure to download the Jio mbn file (mcfg_sw_reliance.zip) from my previous messages and use it when following this guide:

Here was a Guide. Someone said people don't care about Me or My Work so...
forum.xda-developers.com
2)install magisk
3)connect you mobile in adb shell
#adb devices
#adb shell
#su (grant root privilege to adb shell in magisk )
#setprop persist.dbg.ims_volte_enable 1; setprop persist.dbg.volte_avail_ovr 1; setprop persist.dbg.vt_avail_ovr 1; setprop persist.dbg.wfc_avail_ovr 1
Now uninstall magisk from inside the app...all the banking apps also working
thats all just reboot ...it will be enabled.

Thanks for sharing @RKONLINE. Did you manage to get Airtel working in either of the slots. I am yet to find an MBN that not only makes Airtel work on both the SIMs but also retain Jio's VoLTE and VoWifi after that. Please let me know. Thanks!

I am stuck at sin / unsin step and not able to follow steps . Checking whether VI network works with Xperia 5 iii , if so I will move to VI .Else looks like BSNL supports 3G still
@anmolkakkar Will be very helpful if can post simpler steps help me through a remote session (I am not very familiar with modding etc)

You are an absolute legend thank you so much. For me on my XQ-BC72 Xperia 1 III this worked and has unlocked VOLTE for my UK networks - didn't have to faff around with MBN files and whatnot. Thank you so, so much!

I have a different rom from ones in xperifirm. I am trying to flash rom from Xperifirm and unable to build FTF Rom file using sony mobile flasher since it does not have device support.
Can anyone suggest steps

Which model do you have and which firmware are you trying to install? Additionally, which mobile network are you on for which you need the VoLTE / VoWifi to work?

Thanks for enquiring. I have XQ-BQ62 dev phone without drm where I installed ROM from Xperifirm.
I am on Airtel and the phone disconnects from 4G and calls using 2G network of Airtel. In the process several time there are call drops.
When I try to patch SIN using Magisk, I am getting below error
- Device platform: arm64-v8a
- Installing: 25.2 (25200)
- Processing tar file
-- Copying: boot.cms
-- Copying: boot.000
! No boot image found
! Process error
! Installation failed
