Hi all.
I have the A2017. Before Nougat came out, I was using the US firmware (B29).
I was able to change to network type to LTE only using the service menu (*#*#4636#*#*).
Since 7.1.1 came, I began using the Original, Chinese ROM (currently using 7.1.1 B12).
I still have the same service menu, but the phone doesn't respond to any setting I set for the network type. Only when changing in the Dual Sim settings menu it does respond to my settings, but there is no LTE only setting there.
Can someone who uses the US B19 please check if it works for them? If it does, I will try to flash the US ROM.
Thanks.
Changes in that menu only apply to sim 1. If you're trying to edit sim2, then no go. Still works here (for sim1) on a2017u.

So you're using B19? Then I should too. Because I only have one sim, and it doesn't work for me at all.
I hope it's only related to the ROM and not to the modem, as I do have to keep the Chinese modem anyway.
I'm not sure how that menu works on a 2017G. You could try the app from the play store Network Signal Guru. There's an option in there call change RAT settings. That allows you to change network modes too. It does require root.
I am on Three (UK) and I now understand that wifi calling is a carrier feature and a phone purchased direct from samsung will not have this enabled.
I have found that you can flash carrier firmware to enable this but I have a few questions:
Can i do so without the carrier bloat such as a horrible boot screen and preinstalled apps?
Will this affect my Knox / android pay / secure folder access?
Is there any way I can flash the wifi calling functionality without a complete reflash?
Thanks
Does 3 have WiFi calling? I don't think so.
Unless it's new. I left them in Feb after many years to get Volte. There was no voWifi then.
The reason I ask is voWifi worked out the box on my unlocked BTU S8 with EE.
Volte did not and required me to flash the EE firmware. This works a treat. No knox trip, no branding or bloat, no AP or secure folder issues.
If you want supervoice, you will need to flash the firmware.
Edit - seems I was speaking bollocks, yes they have WiFi calling, called "embedded wifi" now. As said, with EE this worked out the box for me. Only needed their firmware for Volte.
Three does have voWiFi aswell as voLTE/vo4G (In select areas).
Call Three and make sure WiFi Calling is enabled on your account and then you should receive a carrier update adding the WiFi Calling option.
(Source: Method I used with Vodafone UK)
I though three used an app for WiFi calling? Or at least that was the only way I could get it to work when I was with them a few years ago.
Edit: I've just read that they have built in vowifi but only on certain handsets. Perhaps the s8 isn't supported as yet?
I did a chat with them, S8 is supported for voWifi it seems.
Here in Poland, phone with non branded system works with WiFi calling. There's setting in dialer options (three dots menu). After I toggled it on wifi calling started to work.
TIM purchased s8 here, flashed the h3g firmware and volte and WiFi calling both function.
Bloat is there (boot screen and m$ office).
No call to three required to activate, it just works as soon as the correct CSC is on the device

Three's website does confirm the S8 is compatible for WiFi Calling.
Go into the Phone app, press the three dot's -> Settings and see if there is a WiFi Calling toggle, this is at the bottom of the list.
If WiFi Calling is not there, make sure you have the latest update installed.
Update via the following guide from Three themselves: (please add a :// after http and make sure there are no gaps as I am not yet allowed to post links): http support.three.co.uk/SRVS/CGI-BIN/WEBISAPI.dll/,/?New,Kb=Mobile,Ts=Mobile,T=Device,varset_pid=40031,varset_cid=40041,Case=EXT(EM114337)
I've literally just switched from BTU to H3G and WiFi calling appeared instantly during setup. I did have to use CSC rather than HOME_CSC, as the latter caused Odin to fail first time around. I have also confirmed WiFi calling and texts are working, which is a huge plus as the lab in which I work seems to block all mobile signal!
Did installing H3G also enable VoLTE?
Cheers
Thanks for the quick replies everyone! Wifi calling is enabled in my account (it worked on my iphone) but the wifi calling option is not there at all. (I've checked all guides, including the 3 dots then going into phone settings) I know there is an app but it is horrifc, calls often don't come through at all, the app requires a persistent notification and is a major battery drain. @goRt @foo25 - > did you guys follow a guide for flashing three firmware? Do you know of any way to avoid the carrier bloat / sim lock?
Thanks all!
I've just flashed the three firmware from the Samsung version. After flashing, inbuilt Wi-Fi calling just worked. Wi-Fi calling toggle also appeared in phone- 3dots- settings menu. 800mz band 20 LTE also started working after switching firmware which means an extra bar or two when band 3 LTE signal is low.
The only downside I could see is the three UK splash screen on boot. I haven't noticed any extra bloat apart from the three likes app which I uninstalled straight away.
The phone is not SIM locked by flashing the carrier firmware.

I didn't follow a guide but there are plenty around for flashing stock firmware on the S8 or S8+.
I just downloaded the latest version of Odin, and then the latest three.uk firmware from Samobile. I unzipped the firmware then loaded each of the components into the relevant Odin section ie. CP into CP section AP into AP section etc. I made the mistake of loading the 'CP Home' firmware into the CP section of Odin which caused the flash to fail which required use of Samsung emergency recovery procedure. I did that three times before trying loading 'CP' part of firmware into CP part of Odin which worked fine.

*Download latest odin
*download desired firmware. (samobile) and extract it.
*go to settings>about device>software info>tap build number 7 times until developer options enabled.
*go to developer options and enable USB debugging and OEM unlock.
*plug phone into pc and let it install the drivers.
*turn off phone and boot to download mode.
*open odin and click AP. Insert the firmware you just downloaded.
*odin options should be: auto reboot checked, F reset time checked, repartition UNCHECKED.
*connect phone to odin and it will say added. COM box will turn blue. Just click start and let it do it's thing.
The first boot up can take a short while.
Thanks to everyone for the detailed replies.
One more question: I use secure folder and plan to use android pay. My colleague told me that flashing a new firmware will trip knox which will render these features unusable.
Will flashing the official 3 firmware do this? I'm only flashing to get a feature as advertised (there's a lot to be said for iPhone's just "working" )
Thanks

Aslong as you flash official samsung firmware then knox will not be triped as its signed by samsung. Knox only trips when flashing twrp, root or any custom roms.
Before you start, do you have the option for wifi calling in phone>settings right at the bottom?
Like this
Hi all i have flashed my btu s8 to h3g and i also have the wifi option in the menu and it works great, however i can't find the volte option anywhere and i have never yet seen the symbols for it on my status bar.
When i had my old btu s4 i also flashed that to h3g and i remember the volte symbols showed up in the status bar.
So do i need to do anthing to activate volte?

Hi there,
There is no option for volte, if your network supports it then it will automatically be on where ever you have 4G signal. There is no option in settings but the icon looks like in the screenshot
I went from stock Nougat to several variants referenced here
Whether I'm using RR, Nuclear, etc.......the t-mobile signal is so weak that I'm unable to make phone calls.
Using TWRP 3.1.1. All installs have been clean, wiping system/cache/dalvik/data on each.
Is there something I should be checking or installing to fix this?
I may have solved my own problem.
For those who have the same issue, disable VoLTE:
Settings - Wireless & Networks - Cellular Networks - Enhanced 4G LTE Mode.
Which rom has volte function
Hi Everyone,
At home, we get two RN7 global.
My wife get official global MIUI 11 latest.
Mine is with LineageOS 16 unofficial from June 19.
Both have the same french prodiver.
We live near the boarder (not good side of the provider) , but no matters, in Europe there is facilities with Roaming.
At home, both telephones near. My wife can find our operator, and on MIUI she can choose the bands (operator 3G, 4G, 2G etc) and stay connected on it (with weak signals but it works).
On LineageOS, it only detects the operator name. and when I connect on it, switch automatically to the abroad operator... can not force manually.
What should I do on my phone ?
Change roms? which one let me choose network bands?
Update firmwares?
I use a great ignored app "Phono"
From this site : phonoins.blogspot.com
It allows to get the logo of the provider in the status bar and identify easily if on roaming or not (instead of the really small R logo on the network zone).
Works on my roms, but not on official MIUI
Someone knows a good app like this ?
Thanks for your precious help.
Regards,
Jc.
To reply.
I upgraded to PixelExperience Latest.
I add some little troubles because my /data was encrypted (stuck on G logo at first boot). So need to erase /data partition.
With PixelExperience the "manual mode" is available and my phone doesn't switch randomly to another provider.
So my old rom LineageOS 16 is bugged and does not allow "manual mode" for cellular/network mode.
I will replace PixelExperience with something else. First feeling, I dislike it.
I found something called Network Info Lite that suits me partially... but still no logo in status bar. Will retry Phono with my new custom rom.
