As per thread title.
Unrooted, stock Galaxy S7 Edge with latest available firmware.
Under Settings -> Mobile Networks I have a VoLTE Call switch which is on, and network mode set to Auto (LTE/3G/2G).
Weirdly, when I'm at home which is definitely within a Three 4G coverage area (with, allegedly, support for VoLTE or "4G Super Voice" as they're calling it), if I reboot
the phone, a VoLTE icon appears for a short while in the notification bar and then disappears.
Three's webpage talks about S7 Edge users needing to get an update, but their instructions just direct people to do the standard android check for updates, of which
there don't seem to be any newer ones. So clearly, the phone IS working with their VoLTE support but other than the Icon's brief appearance, there's no way to tell
if it's actually working.
Oddly, friends of mine with S7 Edge's bought around the same time and on EXACTLY the same firmware (build, kernel etc.) don't have that VoLTE option at all.
Any thoughts?

You need to add an IMS APN
Hi
As for VoLTE to work, you need to add an IMS APN, usually as follows:
Name: IMS
APN: ims
Authentication type: None (sometime PAP)
APN type: ims
BR,
xe
Thanks, I gave it a try that but it didn't save, even though I pressed the save button. The new APN I tried adding didn't appear after a reboot either.
Also, the "Three" APN that is currently there isn't editable either unfortunately.
Is there a way to get VOLTE working on AT&T in the US?
I have Three and have VoLTE and I switched from the carrier branded to the unbranded BTU version of the software, unrooted. Maybe you could try that?

Would love to know how.. teach me please sensei
My phone was bought sim Free/unlocked from Carphone.. all I did was stick a Three sim in it...
I have an unlocked S7 edge "BTU" firmware and volte does show on mine when i'm in the office. Not that its any good, no one can hear me when i talk to them, i hear them fine. Your friend may be on the xeu firmware which AFAIK doesn't have volte option (Dont quote me on this!!). I think the signal on this phone is shocking actually, my Z5 premium had much better signal. I'll persevere with the S7 edge though.
Search and download odin.
Go to sam firmware and search for G935f (that's your phones model number.) you'll then get a list of firmwares, scroll to United kingdom and click on the btu firmware. (i tried threes H3G firmware and volte didn't work.) Download and extract the firmware. Downloads are sometimes really slow on there so be patient or search for a faster download. The latest UK firmware is: G935FXXU1APD3
Power down your phone, once off hold volume down, home and power button to get to download mode. When download mode shows, press volume up to agree.
Open odin once the samsung drivers have installed for download mode.
Click BL in odin then select the BL file from your extracted firmware
then Click AP then select the AP file from your extracted firmware
then CP then select the CP file from your extracted firmware
then CSC then select the CSC file from your extracted firmware (NOTE: there's 2 csc files don't select the Home_CSC file)
Odin should say your phone is connected.
THE NEXT STEP WILL WIPE YOUR PHONE!! PLEASE MAKE SURE HAVE BACKED IT UP AND WERE NOT RESPONSIBLE IF YOUR PHONE BRICKS.
Press Start on ODIN and wait about 10 minutes, you should see a progress bar and then "PASS" once done. Your phone will probably reboot once done.
Good Luck from a fellow 3 user

I'm also on Three and have the S7 Edge and I dont have this option. It could just be embedded in the firmware file.
It was a sim free phoneb that I got from car phone.. what's weird is that four friends also got new skin free phones from Samsung directly, all of the firmware and kernel numbers match but they don't have it. Also, even with the option on mine, VoLTE doesn't really work.
So still no clear idea from anyone about VoLTE support. However I noticed that VoLTE icon appear in the notification bar whenever I'm in an area with no mobile coverage. I can't make a
call mind you, but yeah.. has anyone else who hasn't had VoLTE working on a Sim free S7 Edge, but has the option turned on, seen this? My wife's S7 Edge is also exhibiting the same behaviour.

Hi
You can try to pull out the customer.xml file under the /system/csc folder and edit the APN profile (to add IMS), then write back to the phone. It will work well, but need SU access to do this.
Regards,
xe
Looks like they've removed this switch in the latest (September) update. The VoLTE icon used to appear briefly in the notification area on first boot but no sign of it now. No real reliable way to test as network coverage is weird where I live so I can only guess at what Samsung have done.
According to someone on the Digital Spy forums, they tested after the update and still had VoLTE functionality even without the switch toggle - so I guess Samsung
have just baked it in now.
I have S7 edge unlocked from Samsung. I was on Tescomobile (O2) and I've just ported to Three. I don't have the Volte option but I do get the Volte logo on the top of the screen from tine to time. At the weekend I was in a no signal area but I had the Volte logo so I tried a couple of calls. On some calls they couldn't hear me though I could hear them. On others it got almost acceptable two way calling. I'm guessing it is working.. just.

Sorry keV didn't see your reply. Have you got it sorted with a newer firmware?
Sent from my Pixel XL using Tapatalk
I am on Three Austria (No VoLTE support on this network anyway). Just wondering if (since I recently flashed the unbranded UK BTU -full conversion to BTU to get Nougat and BUT OTA's) will VoLTE work on BTU even if there is no button in any settings ? Not in dialer or network settings.
I guess my question is if Three Austria implements VoLTE will I get it on BTU or will I have to flash back to DRE (3 Hutchison Austria) back again?
Some people have said starting from Nougat providers can push the settings to the phone and no custom firmware is needed, no verification of this info though.
The only provider in my country that supports VoLTE (A1) claims NO you need their firmware.
Maybe I can source an A1 sim and test this.

Hi All,
I've got terrible signal where I'm living at the moment so I'd really benefit from getting the wireless calling through the EE firmware.
I've downloaded the firmware file but I'm a bit stuck. The firmware file itself has extracted to five separate files:
AP...
BL..
CP...
CSC...
HOME_CSC...
I'm assuming that I've got to select all of these within Odin, however I'm unsure of the difference between the two CSC files. Both seem very similar in file size.
Does anybody know the difference and which one would be the correct one to flash?
Cheers
What was the format of the file you extracted those from?

It was a zip file from sammobile:

How do you tell what is on the phone mine said it was coming from ee but then it said it was coming from the company I used which was buymobiles.net so I don't know if I have a proper ee one or a sim free I guess so might flash software once you work it out
You've probably got an unbranded one like me. It's usually pretty obvious when booting up whether it's carrier branded or not.
Think I'll wait for now until somebody can confirm the difference. I'd like to know what it is that I'm flashing
Yeah I think I am unbranded I do have the wireless option and it is on my package I called to check might turn it on it says it can take 24 hours to turn it on.
I've got no option for wifi calling in my settings. Boo! ;-(
Mine is settings, applications, phone then wifi calling at the bottom why would I have it and you don't my phone is not from ee weird
I have the option and my handset came from EE but appears to be unbranded.
Perhaps the branding isn't as obvious on the s7 then. I definitely don't have the option in there
My CSC is XEU with the firmware on my phone

OK so for anyone thinking of doing the same, I have gone ahead and flashed the firmware and enabled WiFi Calling.
I selected all files in Odin with the exception of "HOME_CSC" (I used the standard CSC_EVR).
After enabling the option in Settings -> Applications -> Phone, I text WiFi Calling to 150.
As I'm in an area with crap signal I can already see the WiFi calling symbol in the nav bar and have made a few calls with it. All seems well.
Some very subtle changes in the EE firmware but very close to the stock in terms of branding.
@mmotti The EVR firmware on Sam Mobile is shown as G935FXXU1APB9 is that the one you flashed that enabled wifi calling on EE? Thanks.

Flash the CSC file that contains a PIT file in it, The firmware on Sammobile has a CSC file called "CSC_EVR_G935FEVR1APB4_CL7211170_QB8683672_REV00_user_low_ship.tar" and that's the one you need to flash, otherwise Odin just get stuck if you flash the "HOME_CSC_EVR_G935FEVR1APB4_CL7211170_QB8683672_REV00_user_low_ship.tar"
I bought my phone from the Samsung store, and flashed the EE firmware, it will wipe the device(or did for me anyway). but now I have WIFI calling and working perfectly, only issue with using the EE firmware is that firmware/security updates are super slow :crying:

I did it and everything is fine. I got WIFI calling that is working and that was my main priority. Doesn't seem to be any downsides compared to the XEU firmware.
Hey everyone.
Thanks guys this is just what I was looking for, im using an EE sim on pay as you go but I have an unlocked Galaxy S7 Edge that I bought online NOT from EE.
1. So If I install this firmware I should be able to use wifi calling and hd voice?
2. Are there any downsides to flashing this firmware?
3. Will this reset any settings in my phone do I loose any information.
Thanks
Thanks for your help
Hi,
I am totally a newbie to Android, just moved from IOS, so please bear with me.
I am trying to make Reliance Jio sim work on my Samsung S7 edge (Sprint). Data is working just fine through Reliance jio sim on my mobile. But I am not able to activate Volte on mobile, so calls are not getting through. The Volte turn on/off tab is missing. I searched on the internet and found out that Sprint's network does not support Volte, so they have disabled the tab for it.
My model is SM-G635P
What is the best way out?? Do i have to root my phone??
Thanks in advance.
I am not aware if this will work with Sprint, Carrier locked versions are a little different, plus its Snap Dragon but this is what i did.. You need to change the CSC usually but yours being a sprint one, there will be some modifications for sure , I am pretty sure you wont have an INS CSC in your phone, so you might have to change to a stock US or UK one or maybe T Mobile. I would wait for an expert to tell you that for sure
This is for Reliance JIO Users - You dont need to flash your ROM, you can change your firmware to INS CSC and it works.
1) i used the Phone Info App (Download from the Google Play Store) and saw what CSC Codes were available for me to change to.
2) I downloaded a new firmware from Sam Mobile - You can google for them entering your model no - G-935fD, i am not sure if they are available here in XDA as well
3) My phone supported India CSC (You can see supported CSC's using the Phone Info App so i downloaded the India one it could be different for others.
4) I then downloaded ODIN and used the tuorial in this forum to flash my phone and change the CSC code.
https://www.youtube.com/watch?v=7SK3IMprKVQ this is the link with a step to step guide.
5) After that i factory reset my phone and downloaded the July Update Patch.
My phone after that has been able to make calls and i can see the VOLTE symbol, depending on the firmware it should either automatically come or you might have to manually enable it.
Hope this helps everyone else also. Factory reset usually helps and downloading the latest update too..
The method above will not work with Sprint Phones. Attempting it may brick your phone.
Activating VoLTE will mostly require some work at the root level. Hope someone who has knowledge about it can help you.

Hii..utkarsh86...I am currently using samsung s7 edge sm-G935F exoyns version from germany 1&1. I live in India and want to use jio VoLte. Is it possible for me to do so..if yes can you please tell me which firmware would support my phone. I tried phone info app but it does not show any available CSC is it fine if i flash it with any other firmware...please help..
Product Code: SM-G935FZDAXEG
PDA: G935FXXU1DQB7
CSC: G935FXEG1DQB2
Baseband: G935FXXU1DQB3
Bootloader: G935FXXU1DQB7
Try searching through the forums for your answer instead of posting another needless thread. I have answered how to fix the VoLte problem so please search.
Hello All,
I have S7 edge bought from Singapore. I have downloaded Phone Info app and following are the details :
Product Code : SM-G935FZSUXME
CSC Code : XME
Available CSC Codes : CAM, GLB, MM1, MYM, SIN, SMA, STH, THL, XME, XSP, XTC, XTE, XXV
CSC Country : Malyasia
I have got Reliance JIO card and trying to activate it. Unfortunately I cannot do it since current version of firmware does not support VoLTE. I need to move it to some firmware which supports VoLTE.
Let me know if you need any other information in order to give me suggestion on how can I activate my Reliance Jio card, without rooting the phone. In case rooting the phone is the only option, I would like to know if I would continue to get the updates given by Samsung in future ?
Thank you in advance.
Yes it is possible to do it without rooting you just need to install the CSC Firmware of the country you want to change it to, using ODIN i have mentioned the steps in a previous post its not a big problem and very easy to do.
PS- the India Firmware supports VolTE but you must ask if you can install it over even if the phone doesnt support that version, i think you can but i am not sure

Hi Utkarsh,
Thank you for your response.
Whom should I ask ?
See the thing is i have a solution, and i know the Indian firmware version supports VOLTE, It is about finding the firmware version of the CSC that the phone supports.. What i am not sure is if you can install a CSC fimrware that is not supported in your phone, for that send a PM to mods or people who know. I will list the steps that i did
- You dont need to flash your ROM, you can change your firmware to INS CSC and it works.
1) i used the Phone Info App (Download from the Google Play Store) and saw what CSC Codes were available for me to change to.
2) I downloaded a new firmware from Sam Mobile - You can google for them entering your model no - G-935fD, i am not sure if they are available here in XDA as well

Hello,
I did see this post over here in XDA, but my issue is that my phone does not support India CSC. As mentioned in the original post in Phone Info shows me the following available CSC codes (Missing India ) :
Available CSC Codes : CAM, GLB, MM1, MYM, SIN, SMA, STH, THL, XME, XSP, XTC, XTE, XXV
Hence I am not sure if installing Indian firmware through ODIN will help or not. Do you know if that will work ?
I can confirm that is possible to change via Odin without root the CSC even to one which isn't currently available. Yesterday I've changed my CSC from ROM to ORO in order to have access to VoLTE and VoWiFi. I'm not rooted and OTA update it's working. One thing to cosider is that the phone will reset to factory settings.

Ok perfect. I am downloading the Indian version of the firmware. Will keep you updated. Just hope that my VoLTE get's activated !! Keeping my finger's crossed !!
Also, thanks for the quick response.
Depending on network, sometimes it's necessary to send a SMS or call a special number in order to activate VoLTE.

Hey I was successfully able to reset my CSC to INS (India). So thank you very much for that. But I am still not able to see the VoLTE option in my Dialer -> More -> Settings, which most of the people have confirmed that they see it.
I am on Reliance Jio and Idea in Gujarat, India Are you aware what should I dial to enable VoLTE ?
My phone is getting an update, just hope that it helps to get me to see the VoLTE option !!
It should be in Settings/Mobile Networks
If you phone is not rooted you needed Volte option in your device than yeah you needed INS CSC to get option in Indian Carrier.
So simple and best way is to Download your Samsung S7 edge INS firmware from sammobile.com and enjoy.
or you can try custom Rom so try exyfire Rom for S7 edge and than flash INS CSC whose Zip is available to download.
Just download the following zip file and flash it using TWRP. In the Aroma Installer choose Indian CSC option and you are ready to cruise on the Jio craze. No need to flash any FW

I am facing the same issue. I am still not getting VoLTE option. I flashed phone with latest Aug 2016 INS firmware from Sammobile which has July 2016 security patch. Once flash without factory reset, second time flash followed by Factory Reset. Still no luck.
Later check with Samsung and Jio Helplines and they say S7 Edge will not have VoLTE option under setting, it is active by default, but none has an answer as to why VoLTE logo doesn't show up? If i have to make calls, the same gets routed through Jio Join App and if i uninstall the App the calls doesn't go through at all.
Some Expert please help!
I have the Samsung S7 Edge SM-G935FD bought from UAE, (Made in Vietnam) and it has multiple CSC but not for India (INS not present in CSC list).
I was getting 4g but no Volte, so no calls/sms.
I read this entire thread last night. Got the latest India firmware.
Flashed as per post #42 of this thread. Wiped cache,
After rebooting, I got the LTE sign, but still no Volte, checked for latest updates, I was all up-to-date.
Put phone on flight mode and back on.
And voila, Volte!!

1. Download Samsung smart Switch.
2.Click more on the right corner
3.Click Emergency Software Recovery
4.Click Device Intialization
5.Put your Model no
6. You need the local INS serial no ( Check Google with model no- I got one from a face post for SM-G930FD)
7. Click Ok, and follow instructions.
8 After Phone restarts clear cache memory. (Check Google with phone model)
9 After phone restarts Volte appears.
Thank you.

Do you mean the Samsung Smart Switch mobile app? I dont see any option that says 'Emergency Software Recovery'
Hope someone can help me with this issue!
I have got an officially unlocked T-mobile Galaxy Note 4 device connected to Reliance Jio 4g network in India. This device supports Band 3, 5 of the Reliance 4g LTE services (Band 3, 5 and 40). Just to let you know, I can manually chose either of the bands (3 or 5) using *#2263#. I can't use *#*#4363#*#* on my phone.
I can use data LTE services on my mobile without any problem.
Under the Call Settings, I have the option to enable "Voice over LTE". (done that) however, I can't get VoLTE calls to work on my phone through native dailer as VoLTE icon doesn't appear on my phone.
I can make calls only if I use Jio4gVoice app but the call quality is poor with the app.
If I use my Jio sim in my Moto G4 plus device, VoLTE icon appears on the phone and I can make calls without any issues.
Before coming here, I have talked to
1. Samsung India - they directed me to Samsung USA or T-mobile
2. Samsung + through the Video chat with Samsung plus representative in the US. They directed me to T-mobile.
3. T-mobile - said device belongs to me and can be used anywhere in the world without any problems. Asked me to talk to Reliance JIO.
4 JIO - they say the phone should support VoLTE and LTE services. They have been taking my requests to resolve the issue and closing them every other day but without any joy. I have told them that under About Device > Status IMS registration status shows Not registered.
So what needs to be done in this scenario? Do I need to replace Tmobile CSC (TMB) with an Indian CSC? Is that even possible? Seek your help and hopefully it can help others. Thanks in advance!
LTE Setting?
Hi
How could you enable Voice over LTE setting?
even i have SM-910T.

I just followed the following menu:
Settings > Call > Call Settings > Voice over LTE Preferred (turned it on)
I have been seeing this option on my device ever since 5.1.1. Have you updated your device to latest 6.0.1?
Have you been able to get any satisfactory answers about VoLTE on Jio?
Thanks
is this the N910S?

Did you create an IMS APN for Jio? Assuming you're already getting 4G data, head to Settings > More Networks > Mobile Networks > Access Point Names. Click + on the top to add APN and enter the exact following stuff (case sensitive):
Name - ims
APN - ims
APN Type - ims
Save and exit. In all probability, you'll not see the new APN in the list of APNs, but VoLTE symbol should come up. Hope it does, otherwise tough luck.

I have tried to create APN as you have mentioned it but can't get to save the new APN.
I have noticed one more thing in STATUS i.e., IMS not registered - is that the culprit?
When I put the same JIO sim in another phone (Note 4- N910G - Indian version) it shows IMS registered and both LTE data and VoLTE work flawlessly.
Wondering if IMEI and the t-mobile are the culprits?
Thanks

It could also be the CSC. You may have to root the device, and flash INS or INU CSC (I'm using INS on the 910G) ace see if that fixes anything...

Can you check in the T-Mobile forum? I'm not sure about the differences between a branded and an unlocked device firmware-wise, don't want you risk a reflash.

I would really like to flash this to a completely TMobile version so I can get 4x4 MIMO & 256 QAM features but I am looking at http://updato.com and I see 2 different versions. SM-G950U & SM-G950U1. SM-950U USA TMB G950USQU1AQDE May 1st 2017 or SM-G950U1 USA TMB G950U1UEU1AQE3 June 12th 2017 . At this point I am confused on how I should proceed. If somebody could help me figure out how to proceed I would appreciate it. I have done a lot of flashing and unlocking bootloaders going back to my original Droid X but I really don't want to brick my $800.00 dollar phone right away.
Note: I have read [Snap.] Guide for Flashing Standard FW, Carrier Switching, and Flashing Unlocked FW and I am still a bit lost. Hope this is enough information for someone to send me in the right direction

Might be a TMobile software tweak that enables the NFC icon to show up in the notifications. Might not be enabled in the Unlocked Versions.
BTW What Model # is your wifes phone ..... I can't figure out if I should flash the G950U or the G950U1 ...

Are you sure that US unlocked model on T-Mobile isn't getting "4x4 MIMO & 256 QAM"? In the specs on Samsung website it shows: VHT80 MU-MIMO,1024-QAM, don't know if it is any different.

How to verify that SM-G950U1 do or does not support 4x4 MIMO & 256 QAM on T-Mobile? I might flash my unlocked unit to T-Mobile only if I know for sure that my device doesn't support it.

I'm not sure if it does yet but I would assume so since you are flashing the T-Mobile firmware .. I have tried many different methods of finding out if it does via the device but I think you need root. I tried multiple applications from the play store and used multiple phone codes to open every menu available. I got to the ServiceMode to change bands by using *#2263 / I got to ServiceMode with Debug that gives information about the current Band that you are on and how many MHZ you are running at. It also gives you some additional info: RSRP RSRQ SNR. Unless somebody else has a way to figure this out without root I'm not sure. Also Ill add a list of the current cities with 4x4 MIMO below. I did verify that all HD Voice, Wifi Calling, Video Calls, & Volte work .... Verified by downloading Shortcut Master Lite https://play.google.com/store/apps/details?id=org.vndnguyen.shortcutmaster.lite&hl=en ( Under App Explorer / System Apps / IME Settings / ImsSettingsLauncherActivity / Launch ). I am happy with the TMobile Version .. It has T-Mobile App installed and Lookout but there is ways to disable those and remove them without root. I haven't removed them but i read it is possible ... Doesn't use much RAM. If you need anything else let me know!

So from your 1st link, I do see that my city is there (WA), but second link, didn't have it.
I have done flashing via Odin many times on my previous Galaxy phones, so I feel comfortable, but I am kind of debating...if I really need to flash and if I will benefit from this.
I will ask you few questions and it may help me make a decision:
1) Have you measured download speed using Speed Test before flashing T-Mobile firmware? If yes, any difference?
2) I hear that my phone calls are clear and pretty positive that HD Voice is there, even though there is no icon.
3) VoLTE, Band 12 and WiFi Calling are supported and work well. Never had a reception issue or call drops, at least not yet.
4) As for RCS support, do you see it often when you text other users?
5) Video calling - your phone should have it, have you used it?
6) How is battery life compared to an unlocked software that you had before?
From the list above, I would flash to T-Mobile if: #1, 4 and 6 are working properly to make user experience better. I do know that RCS even on T-Mobile is limited to phones that support it, for example Glalaxy S6, 7 and 8 and possibly Note 5. Also some LG phones I believe had it as well.
In other words, what did you gain when you went for T-Mobile firmware?
Before I forget, you used Odin and added needed files such as BL, AP, CSC(you probably didn't you HOME file, just CSC) and also USERDATA TMB file - I am correct?
Any updates on whether or not the Unlocked USA S8 supports 4x4 MIMO & 256 QAM on T-Mobile? I've flashed the T-Mobile firmware on my unlocked phone and haven't noticed any speed decreases or increases. Any new way to verify that s 4x4 MIMO & 256 QAM is actually active with the unlocked firmware? I believe it is doing 3x CA though...

I am trying to find that info for sometime... I have seen somewhere that there is/was an app in play store which was similar to LTE Discovery, but it did show more info on 4x or QAM, I don't really remember. That time I didn't need this info, so I didn't really pay attention. I found this site that has some info: http://www.howardforums.com/showthread.php/1888849-How-to-tell-if-using-4x4-mimo
