No Volte support in galaxy s6 sm-g920f

Hi guys,
I'm new to this site and I hope someone can help me out.
I'm using a galaxy s6 sm-g920f bought from UAE in India. Here there is a new network operator called Rjio started operation and I managed to get a sim. The problem is that they support only LTE network and Volte calls. I cannot make calls from my Sm-g920f.
I tried searching all over Internet and couldnt find a solution. I tried going to Phone>more>setting but couldnt find any volte setting.
Can someone here help me out??
I'm using the latest os and firmware.
Model : SM-G920F
Android Version: 6.0.1
Baseband version : G920FXXS4DPG6

The problem is with the firmware. Earlier some one had this problem and members told him to flash Indian firmware. So that the bands allotted shall work. So either you can wait for the reliance jio to add the devices or you can just simply flash the Indian firmware.
Thats the problem.. G920F model does not have an indian firmware. Indian firmware only available for G920I

[HELP] voLTE problem after nougat update

Hello guys,
my phone is Samsung galaxy s6 G920F from UK and voLTE was not working here in India. (needed voLTE for calling on Reliance Jio network). i tried all possible thing available but it didn't worked for me. i tried changing CSC to INU/INS etc but none of that worked. Then i found this forum and by doing that it worked like a charm
https://forum.xda-developers.com/galaxy-s6/general/volte-fix-g920f-jio-users-root-t3550917
now my real question is that what i did to make voLTE work in 6.0.1 (using above forum), same i did for 7.0 but unfortunately it didn't worked.
So is there any way to get voLTE on 7.0 in S6 G920F because i have seen many different phone model owner on xda complaining that voLTE has stopped after they have updated to 7.0 nougat.

The reason why it worked previously is that you had CSC files for marshmallow, they probably don't work on nougat firmware. Your only option is to wait till nougat firmware is officially released which supports volte for jio.

Help! Need to change the CSC for S7 SM-G930T

Hi,
I have an unlocked Samsung Galaxy S7 from T-Mobile (SM-G930T). I wanted to use this phone in India with Jio as the service provider. Jio is a 4G only provider with VoLTE. Unforturnately with my S7, VoLTE does not work due to CSC of my phone being TMB. Jio supports VoLTE for phones with INS as CSC. The 4G data does work with the phone. I am hoping that it is possible to change the CSC for my phone. Please help.
Thanks in advance.

-Muru

Follow this guide
Hi,
I have a Samsung s7 930T as well. I want to update to Oreo 8.0. Have found the firmware on SAMmobile. Does any one know if my sm-g930T will accept the g930f update? I assume I'll need to flash the bl, ap and all that to change csc. WIll that be included in the firmware down load? Do I just flash all that with ODIN?
Thanks!

Galaxy A8 VoLTE and VoWiFi features on the USA T-Mobile network

Folks,
I have Galaxy A8 UAE version in the USA with MNVO SIM-card which is working on T-Mobile network. Of course VoLTE and VoWiFi features are unavailable on my A8 because it has wrong CSC (which is XSG). As I understand I need to change CSC code to add the features to my phone. But... as Galaxy A8 is not released in the USA there are no A8 ROM with CSC appliacble for the US. I'm wondering if there are any other ways to change CSC to one which will work with T-Mobile VoLTE (my previous Nokia 6 US-version had both features working fine with the same MNVO SIM). Could someone help me with that?
Follow the directions it works
Unfortunately this has stopped working.
