Ketans rom is for N910G(snapdragon variant of the phone)
We on the other hand is stuck with N910C(exynos variant of the phone)
even though i read that the hardware supports VoLTE, cant find any rom with VoLTE version

Any luck in finding software support for VoLTE ?

I also have a UAE csc Note 4 SM-910C . It shows 4G but the LTE sign never shows up only 4G appear and have to use the JioJoin App which has a reliability of sadly 50% only. If any solutions please respond.

nothing yet, jio4gvoice is the only way out for now.. btw 4g is lte and seeing either of the signs is fine. the thing is we need VoLTE sign to get calling working without use of jio4gvoice app.

How to make Volte work on Samsung S7 edge (Sprint) for Reliance Jio

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.

Your not getting any help because you posted in development section. Had you posted in Q&A someone probably would have told you what you want isn't possible.

Hi, I am currently trying to find a way to enable VoLTE and wifi calling/text on my unlocked S7 Active. This issue is that this phone is exclusive to AT&T and I'm using it on T-Mobile. I stumbled across this thread and saw that you had success with this and the unlocked S7 Edge. Would the methods you used also work for the unlocked S7 Active running on Tmo?
Apologies if I'm in the wrong area of the site. I'm a complete noob to thIs community and the rooting process itself. I have made one post so far asking some questions regarding this topic over in the S7 Active root section. Received a very kind and thorough response (still need to follow up and thank him!)
He did say there are ways to enable VoLTE, but I'd have to research the topic to figure it out. And that's how I ended up here
Thanks so much. Very grateful for any insight.

Thank you guys so much for the direction! I checked out both links. The last one (17-18 pages) looks quite useful, but just after reading the first page, it's very clear that I need to start from the beginning. It was like trying to read a foreign language.
It would probably be safer for me to try to find a beginner's intro to rooting and basic tutorial first.
Hey, you guys should set up a mentor program! I know I would gladly fork over a reasonable donation for some one-on-one schooling
Edit: I have bookmarked the advised links too. Will be returning to them as I become more versed in all this.

Airtel Volte [How to Enable It]

Hey guys, I have finally arrived at a proper result after a long time.
Airtel supports Volte in all areas except J&k. , as mentioned on their website: https://www.airtel.in/volte/
Note: First u need to have an Airtel 4g sim along with a 4g/3g data plan.
So the steps to activate Volte is simple :
1. Go to the airtel Volte website given above.
2. Check for compatible devices
Note: You will be needing any one of the compatible devices listed by Airtel on their page.
3. Now you have to put your sim in the device [ compatible one ] and they reset the network settings of the device.
4. Now restart the phone and wait for some time.
5. After doing so you would get a link from Airtel.
Note: Something similar to this - Please open the following link to get manual instructions for service settings.
http://10.89.22.101:9080/SADM/Manualgrp=Auto+Device+Detection&rcId=4&msisdn=%2B91<airtelmobilenumber>&dev=Xiaomi+RedmiNote5Pro
6. After clicking on the link, you have to restart the device.
7. Airtel Volte will be enabled, now you can put it back in your Zuk Z2 and Volte is enabled.
And for those who want to know what rom I am running on,
Rom: Jaguar version January 10
Gapps: Mind the gapps
magisk: Installed
Hit the thanks button if I helped you.:good:

It's working guys.

I used galaxy j7 which is supported device. I waited for 15 mins and tried rebooting even i didn't get volte or sms mentioned above, Then I called customer care and asked about volte ,then they told your device is volte supported and keep using your device to get volte after 2 mins i got volte in j7 then i switched to z2 plus , volte is working now in z2

ok to solve your issue, all you gotta do is follow this website: https://forum.xda-developers.com/showthread.php?t=3695877 get the latest version of Indian stock rom guess (zui 2.5) and install that using qfil.
now set it up and enable volte on the device. Then follow the steps given above. Happy Flashing :good:

No matter what I try, wait for similar message as given in #1 or call customer care for volte settings they are just providing me with Instructions on how to enable VoLTE in settings.
I'm not able to get beyond that point i.e., not able to receive the link to enable VoLTE on my sim card.

I didn't got any link but kept my sim in poco f1 for 4hrs it's worked for me....
Now i can able to use volte in Z2 Plus....

Add VOLTE Support For UAE 4G LTE Phone ?

Hi,
I own a Samsung Galaxy J5 Pro 2017, Model SM-J530F, which I bought from UAE. The specs on the box shows it as a 4G LTE device. I am quite confirm it does not have VOLTE in the settings. Now that I am using it in INDIA with Reliance JIo services, I badly need VOLTE functionality on this phone to make it possible to make & receive calls. Is there any way to add VOLTE functionality to it ? Any solutions from our developers ? Please don't ask for flashing a custom rom!
Thanks in advance!
( Though I can install JioCare app & use it but the app is not available on Wifi, works only on Jio LTE ( Jio Mobile Data ) & forces to keep the wifi turned off permanently for the functionality. Actually Jio provides 4G VOLTE only connection & it is not backward compatible with a 4G LTE only device. For that Jio uses VOLTE layer from within their JioCare app to support a 4G LTE device )
This phone is still quite smart! Please help!

Looking into your device model, it seems like there was no India release. In situations like this I would recommend flashing the INS version of stock firmware but since it doesn't exist for this model, I honestly think your only option is to root and edit the CSC features file yourself which can be annoying and quite honestly very long process.
You could also attempt to just flash another region and hope that it has VoLTE included. I don't know if this would even work though.

Thanks for the quick response! I really appreciate it but I was just thinking if there is any other way ? Jio uses VOLTE layer from within their JioCare app!

Hi,
If I understand it right, I have to use CSC file & not the HOME_CSC file to see any changes that I desire, right ?
Thanks in advance!
