Note 5 Indian users (SM-N920G) (How to use Jio Sim VoLTE calls)

I have tested this method on my N920G and it worked for me so don't know about other devices
As most of the Indian owners are aware of Jio network Preview offer for samsung flagships phone i.e. unlimited LTE , unlimited VOLTE calls , unlimited sms for 3 months. But there is an issue with the samsung latest update that does not allow most of the users to use Jio sim for making calls using stock dialer also they are getting 4g written on status bar and have to use Jio Join app for making calls and sms.
but i have found a solution to this issue and that is you have to downgrade your firmware to DD3 in order to get VoLte working and then u can update via OTA once it starts working.
All you got to do is flash

via odin and be CAUTIOUS AND TAKE A BACKUP BEFORE AS IT WILL WIPE YOUR INTERNAL STORAGE AND DATA.
i found this solution and wanted to share it with the community
also not much experience in writing threads so bear with me.....

first of all check your device model by going in settings-about device
if its N920G
then download the firmware i have mentioned above and take backup of all ur files as all the data will get deleted.
then install odin in your pc and in your device go to settings- about device - software info- then click on build number 7 times it will enable developer mode
in developer mode switch on usb debugging and OEM unlocked
then switch off the device and press power home and volume down button it will take you to the download mode and then follow on screen instructions
once you are able to see your device in odin click on ap tab and select the file you downloaded and click on start wait till the process get complete and it will show pass

up and running on Volte.. thanks bro.:good:

I had not rooted my phone and I was getting VOLTE already the moment I inserted the sim in the phone. The speed is freaking amazing.

I have the latest update and volte works great. But i want to know it is possible to change lta band? Service Menu open but the code for lte band selection don't work. It seems it is disabled in update.

Sir,
I have N9208 dual sim note 5 bought in Malaysia. It is not showing volte with my jio sim but 4g data is working great. Will this firmware work with my dual sim version.
Please help.
Thanks in advance.

Tarak

I don't think so because this firmware is specifically for N920G devices but you can head over to DR.Ketan's thread as he had got it working on his rom

[India] Any Axon7 users from India?

Hi guys,
So if any axon7 users are in India, I have a question regarding Volte calling.
Does Volte calling work in India on the stock ROM, specifically does it work with jio?
I had the Chinese version B07 and Volte calling did not work. Flashed lineage OS and Volte started working.
Now that nougat is out and working properly, I want to go back to stock but only if Volte works.

Looks like you need to update the APN settings. Try contacting customer care and have them send it to you.

I'm on the same boat, gonna try upgrading to 7.1.1 and see what happens

Tried with RR, volte works, went to stock 7.1.1, volte doesn't work. So it is a software thing, maybe a dev can help fix it?

From my research volte is a software upgrade. Technically any phone which supports 4g can support 4g after manufacturer updates. Volte also depends on the Telecom provider, the Telecom provider has to enable volte on that particular device for it support volte calling.
For most users this is not an issue, because even if Volte is not enabled they can seamlessly switch between 3g and 4g.
The problem with jio is that it is a 4g only network so there is no switch, if your device is not supported then you have to use their ****ty app, jiojoin or something like that.
So unless jio endless volte on the axon7 we are stuck with using jio join or on a stock based ROM.
Then again I may be wrong about the whole thing :laugh:

I found another possible solution

Yes from today started working magically.. On stock 7.1.1 Axon 7 USA Model.. All the best

Are you able able to make calls on VOLTE. Even i have Axon 7 US model and running android 7.1.1. But i am unable to place calls over VOLTE

It does not work for me. I installed stock 7.1.1 and volte did not work. I called customer care, they were spectacularly unhelpful. I tried a bunch of other tricks but it would not work, now I am back on lineage OS and it's working fine.

Try the solution posted in the earlier post. I was unable to make it work but maybe you will have better luck with the us model.

Magic has happened...
I have tried the procedure mentioned in the above URL, but nothing was working. I was unable to add the APN settings as well as unable to enter in to the engineering mode. I have resetted existing APN settings and added the previous jionet APN settings.
Finally lost hope and made my self to use the Jio with Jio 4G Voice application.
But the Magic has happened here and my Axon 7 fulfilled all requirements this time even with VoLTE .
Yes VoLTE started working . Deleted Jio 4G Voice.
Don't know how but try with re inserting SIM cards and resetting the APN Settings.

Yes i am able to make VOLTE calls on my US axon 7 without internet or jio 4g app.. but my dads same phone doesnt work.. very strange phenomenon bro... im not able to make it out. i tried axon 7 toolkit and tried to unlock bootloader and followed instructions.. then before flashing it went black screen like it was supposed to go.. then i had some work and unplugged immediately on the black screen and rebooted to normal..
All of a sudden jio4g calling app said on the top.. " Your phone supports VOLTE please use standard dailer" holy cow i uninstalled jio 4g app and was able to make calls ever since.. all the best..:angel:

I have a2017g model, and i am on android 7.0 nougat. Play store issue is there. I have downloaded 7.1.1 official update manually but does not seem to get install on my device, also the tried fota update which is 456mb, that also doest not get installed, saying update failed, phone not supported ??

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!
