IF YOU ARE UNABLE TO MAKE PHONE CALLS AND ARE USING RELIANCE JIO ON THE SAMSUNG EDGE OR SAMSUNG 7 THIS IS WHAT YOU NEED TO DO..
Okay i have found a solution what works for me SHOULD WORK BECAUSE THE PROCESS IS THE SAME AND IT IS VERY EASY PLEASE LOOK AT THE VIDEO TUTORIAL IF YOU CANNOT FOLLOW THE STEPS I HAVE MENTIONED
IF YOU HAVE STOCK FIRMWARE YOU NEED TO DO THE FOLLOWING STEPS I HAVE MENTIONED
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

4) 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.
5) I then downloaded ODIN and used the tuorial in this forum to flash my phone and change the CSC code.
This is the VIDEO link with a step to step guide.

5) After that i factory reset my phone and checked for latest OTA update.
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.
FOR ROOTED PHONES
IF YOU HAVE ROOTED YOUR PHONE AND INSTALLED A CUSTOM ROM, YOU CANNOT USE THE INS STOCK FIRMWARE THAT WILL RESTORE YOUR PHONE TO STOCK FIRMWARE
INSTEAD YOU ONLY NEED TO CHANGE CSC YOU CAN FIND THE CSC CHANGER 1.6 THREAD IN XDA FORUMS/ MODS SECTION.
YOU HAVE TO FLASH THAT CSC CHANGER FILE IN TRWP OR ANY OTHER RECOVERY SOFTWARE YOU USE AT BOOT UP, IT IS VERY SIMPLE
IF YOU ROOT YOUR PHONE YOUR WARRANTY IS VOID SO PLEASE REMEMBER THAT

Did you put phone into Recovery mode to wipe cache then wipe data/ factory reset.
no
You can do it now.Originally Posted by anupam498 [ Login above or register to see download links. ]
I am glad my post is helping others, its a simple workaround but you have to really look for it to find it.
i facing the same problem utkarsh. my csc code is ect(nigeria). INS(india) is not showing in available csc codes. still can i load ins firmware on my device? will it have any issues on my phone? please reply
I am guessing you are using JIO, so in my steps i have mentioned how to use Phone Info to see what CSC codes they support, You need to see which CSC's are supported and then ask which one supports VoLTE
