Hi, my carrier three in the UK, note supports VoLTE but I have an Unlocked handset not a three branded one. Is there a way to enable VoLTE with out flashing my ROM?
Thanks
Not that I am aware of.
What if I was prepared to flash my ROM? It's there a way to get it activated on the phone?
only ee supports wireless calling pretty sure this won't work on 3, as the carrier has to support it.

Same problem here.
I flashed three UK kdz ver 10b then 10e which has in props flag volte, however there is one problem. Phone software version still isn't correct, shows version OPT2-SI.
I have rooted the phone and have access to the original three UK LG g4, will compare build prop files.
All other customisation (including homepage) is profiled for three UK though.
The problem is that volte is available only on 800 MHz lte band and nowhere on their website is shown where exactly it's available. Three UK allows access to this band only for LG g4 with three UK updated software, not any other phone. Which is bonkers...
Forcing band 20 results in constant search, no network available. Though according to their website Glasgow where I am is enabled (though no coverage map).
Right. After a few hours managed to get it. Will post the detailed way to do it when I get some sleep.
You need rooted phone, three kdz ver 10e, FX Explorer with root add on and hex editor to edit misc partition to show the software you've got three UK phone.
1. Volte enabled, works
2. Coverage of 800 MHz is much poorer (Glasgow) than 1800 MHz, therefore phone won't use much of the volte as this is available only on 800 MHz and the phone will stick to stronger signal.
3. You can force to use 800 MHz in the engineering menu. However, at home I'm getting 25 meg down on 1800 MHz and just 5 meg on 800 MHz.
4. On open Europe version, I was able to force to use only LTE. On three UK version after change I can force it only when manually selecting 800 MHz band. When on 1800 MHz the phone does not connect to LTE (signal bar ok, but data not connected).
4. There is no handover from volte to 3g. If you lose 800 MHz coverage, the call would be dropped (same happens on original three UK handset)
5. Speeds will always be slower on 800 MHz as three UK uses 5 MHz spectrum compared to 10 MHz on 1800 MHz.
Good news, I thought previously that three UK allows access by IMEI but that's not the case.
Not sure if this is worth the hassle for now..

Would really appreciate the full write up, as Three are not currently planning on updating the software for my Phone Z2, so I may try and replicate your work as best I can.
Three ROM on Unlocked International Handset
Please share how I can get enable VoLTE with Three on Samsung Galaxy S5, or HTC One M8?

Likewise, I'd be interested to understand the settings to enable it on the Nexus 6.
LG G3 user here, willing to flash a ROM if needed to get 800Mhz data as an option when I specifically want to choose band 20 from the bands hidden menu.
I'm tempted to buy an LG G4 from Three but I'm worried their firmware might lock out some of the hidden menu functions like band selection and 800 is the lowest priority you'd hardly ever see it if you couldn't set the band.
Definitely be interested to see what other people have got working.
Any update michalpro?
Anything?
Has anybody else managed to get 800Mhz data access on the G4 or non Three branded devices?
OK, took some time to get back here, busy time.
Before you attempt to do anything, you have to know it can brick your device easily.
This is ONLY for LG G4, not for any other device. ALL YOUR DATA WILL BE WIPED OUT.
Download KDZ for Three UK and flash it to your phone via LG Flash Utility. Tested with firmware 10E (in my case had to flash it twice, as phone was FC keyboard and couldn't get past logon screen):
http://pkg03.lime.gdms.lge.com/dn/downloader.dev?fileKey=FW94J0D232WAAC14C8D217E/H81510e_00.kdz
After flashing, your phone will show OPT2 version instead of EUR. But VoLTE and 800 MHz LTE don't work. Essentialy, the firmware did not recognise your phone is from Three UK and disables it.
1. You need to root you phone. How to do it - please check other posts - I used root injection method with Ubuntu.
2. Now, you need FX and FX root addon (my choise as doesn't mess the file permissions). - get it from Google Play
3. You also need Hex Editor Free - get it from Google Play.
4. You need SD card present in your phone for backup.
1. Once you are rooted open FX and go to Root/system
In folder dev / block you will find file called mmcblk0p22
2. Copy it to your ext SD card TWICE, once in any folder as a backup, second time in the root folder - this is the one you'll work on.
3. Now open HEX Editor and edit mmcblk02p22 file exactly as on pictures attached - before and after (you're editing lines 0000aa000 to 0000a040. DO NOT TOUCH ANY OTHER LINE)
4. Save the file, and using FX copy it back to the dev/block folder (replace the file). Make sure FX has unlocked padlock at the top, otherwise won't let you override.
5. Reboot the phone.
6. Using FX explorer unpack archive.tar.bz2 to cust folder in your phone root. It contains modified H3G config files. Make sure you're using FX explorer to get the right file permissions.
7. Reboot. If you use now code to enter hidden menu - 277634#*# you will see that VoLTE settings are active.
NOTE: If you're already rooted EUR software you may try:
1. Edit mmcblk02p22
2. Edit Cust files.
3. Flash over Three's 10D firmware.
Three released 10G today, will try to flash over and see if settings stick.

Indeed - normally to use 800 Mhz on 3UK you need to have no 1800 Mhz coverage. For VoLTE, no 3G coverage.
However, I can now confirm you can force 800 Mhz in the hidden menu.
Tap LTE bands, tap Band 20. Phone will either stick to this or lose the network. If so, go to Settings, Networks and manually select 3 LTE. Sticks then.

Thanks Michael, we appreciate you coming back. Glad you took a while, if you had posted quickly I'd have picked up a G4, but now I've seen the LG V10 I've totally got to have that instead!

I'm thinking also to get v10
Thanks michaelpro for the writeup.
I had some weird feeling yesterday as I was flashing marshmallow that you would update us with a guide
I will probably restore my TWRP backup of Three V10D, unless you think it may be possible I could root marshmallow and use the same guide?
Thanks for coming back to post your explanation, michalpro

For now root possible on Marshmallow with unlocked bootloader. However, Three UK has not yet released their 6.0 soft, therefore not sure if EUR version with modified NV file would turn on the VoLTE. Three announced their software is required.
Plus, the hidden menu code from Lollipop doesn't work on Marshmallow, so we can't force or observe if it works....
anyone own a Three branded G4? i assume your still on 5.1
can you let me know the software version of your handset?
i just got a used one, im on three network and wanted to make sure its on latest, im in V10h-234-20
Build: LMY47D
is is software a three branded one?
Yes it is
thanks mate
do you know how i can test band 20 (800Mhz) ? i believe it will only be selected if no 1800Mhz 4G/3G is available
i want to test VoLTE indoor

Dialler > 277634#*# opens the hidden menu
Field Test > Modem Settings > LTE BAND SELECTION > Tap Band 20.
If you're in the range of the 800 MHz the phone switch to it and will ONLY use it (until restart) or until you toggle WCDMA / LTE in the normal settings.
If you're getting No signal, go to manual network selection (do not change to WCDMA/LTE, leave it on LTE) and search for networks. If you don't see 3 RAT 4G, well, you don't have 800 Mhz.

Hi
Do you have a link for the 10H firmware?

No, I can see it was released 10 days ago but no link to kdz yet. Not sure if worth updating or waiting for MM

i have a modified G4 (using your guide including the very last update changes), the OTA function can't find an update....likely MM not too far away.

OTA usually doesn't work on modified / rooted ROMS, so it's expected behaviour
ps. just checking. I can select band 20 and 4g works. if i select band 3 (1800) it keeps finding signal and unable to lock despite there being 1800 signal. does selecting band 3 work for you? is there a way of setting 4g only - so it works 800+1800 only ? (i know no volte on 1800)

hi, i have seen your previous guide on how to flash a G4 to work with 3's VoLTE
Is this still the case if i want to use VoLTE on a none 3 purchased handset ? guessing simply flashing the 3 stock ROM is not going to work?
Hi, I know snapdragon 650 has cat 7 lte modem and is capable of lte-advanced which in my area is supported, also i have enabled all frequency bands of my snapdragon bands with QXDM,QPST and i see two frequency bands with network guru app but my phone can't do the carrier aggregation.
My guess: xiaomi must have done some thing to make it work
Any body has any idea how to make it work?
I have root access with resurrection remix ROM
Works for me fine on unofficial lineage without any tweaking, I had the LTE + icon showing and did a speed test and got 119Mbps

thanks for sharing, then maybe RR problem
I have the 64GB Global version
Last Miui 10.3.4.0
I live in Argentina, we use this four LTE bands: 2 - 4 - 7 - 28
The phone can connect ok to those four bands individually but I think don’t is not doing CA, not even 2CA
My previous phone Samsung A5 2016 did 2CA ok, I don't remember exactly all the combinations, but I think 7+28 and 4+28 for sure
First of all, how to see if Mi9SE is doing CA without root? I use *#*#4636#*#* and Cellular-Z app
The phone claims to support 3CA; but which are the available combinations?
Tested also the app "NetMonster"; there its shows up to 4CA which I think is fake, so I discard this app.
Thank you in advance!
Yes this device support 3CA, here is supported combinations: https://cacombos.com/device?model=M1903F2G
Yes Netmonster doesn't show correctly. There is app called Network Signal Guru what show real data but require root.
