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.

Activating Reliance JIO - VoLTE on S7 Edge with non VoLTE firmware

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

Dont worry just back up your phone, download the latest OTA updates and factory reset your phone , it should work seamlessly the Indian CSC does not have any setting to turn it on/off , let us know how it went

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!!
Thanks to @utkarsh_86 and @gandhipurav for this amazing thread.

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.

The u firmware is what you want. Just download the latest one... maybe pl2? It will unlock all radio bands. You may have to sim unlock it too. Root is unstable and still won't give you the all of the bands. The hardware is there, but the software controls them.

No volte in India ( UAE variant)

Guys I got my Galaxy S8 3 days back, imported from Dubai. In India no volte is showing up, I guess the firmware needs to be changed to Indian firmware. As the firmware shows Algeria.
Anyone changed the firmware then please help me out.

I'm in a similar situation, importing from dubai due to the recent price drop. Will be getting my hands on the device in 1 or 2 days.
I read in one of the posts in xda that you will have to just factory reset phone and insert indian sim and configure the phone for getting volte and spay. XDA link. Sounds too simplistic to me.
Can you please kindly mention what steps you took to make S8 work with Jio Volte and Samsung Pay. I'm familiar with rooting phones and flashing custom ROMs.
Thanks!

Hey! even I'm in the same situation. S8 from dubai no volte in India. And I'm unable to download the firmware from sammobile.
I had read this on a forum... can anyone confirm if this works??
"This is what I did and it worked for me .. Please note , all of your data will be erased (I.e. factory reset) so take back.up if you want.
1. Power off and remove the sim tray.. Please ensure you have a Indian sim in the tray.. I used Airtel
2. Goto recovery , HOLD bixby button and Volume up together and power up
3. In recovery , chose factory reset .. This will give a warning and then reset everything
4. Chose power off in the recovery and insert sim tray with Indian sim .. you should do this before booting up as your CSC will be configured when you will start
5. Power on the phone , it may goto recovery again.. Chose to restart to system now
Everything will be configured to INS CSC now .. Samsung Pay works now ..
This worked for me , I had imported S8 from UAE . I don't take any responsibility for any damage in the process please .. just sharing what I have learnt from this forum. THANKS"

Yup, it works. I just inserted my Airtel 4g sim before even the first boot and the phone configured for Indian carriers. Later, I wasn't getting ota updates so flashed AQF7 update through Odin using home CSC which didn't factory reset the phone. I even got AQG5 ota update after this. Volte & Spay work fine.

Exynos variant is only available. I got mine hand carried by a visitor to Dubai, so no duty.

So if i travel to India for a short Period, do i have to factory reset, just because i changed the sim?

Changing CSC

Hi guys,
Sorry I just need a quick answer to this and I can't seem to find a straight answer anywhere. I have a G935F on 3 UK firmware and I want to change the firmware to either BTU or XEU, as the updates are ridiculously slow on this software version. I have read in multiple places that the CSC code is hard coded and cannot be changed, and then other places say this is merely cosmetic and flashing a new firmware will enable you to get OTA updates from the new desired CSC code.
Please can somebody shed some light on this for me, if I flash BTU or XEU will I be able to get updates as normal, and also which is better to flash XEU or BTU. If anybody can advise would either of these packages allow VoLTE and Wifi Calling to work? 3 supports them on the firmware I am currently on, but I was unsure if unbranded firmwares would support this.
Thanks!
