A lot of good GSI ROMs are available. Everything works fine except VoLTE. VoLTE does not work with almost every gsi roms for exynos devices.
Though it was primarily circulated that the voice calls doesn’t work on the non VoLTE 4G roms. It’s because Samsung use proprietary IMS implementation (Which is used by VoLTE/VoWifi/ViLTE etc). The codes aren’t available in public so developers can’t enable/port over this function. Here are a few steps one can follow to use Jio sims in any non VoLTE roms.
Steps:
- Download and install Jiocalls App
- Open Jiocalls and grant all the access
- Configure JioCalls
- Try calling or messaging any of your friend

Overview:
The actual catch with the Reliance Jio is that you can't make calls through a non-VoLTE rom, which is a bit of a letdown. That being said, Reliance itself officially launched their own app to solve this issue. It brings VoLTE high-definition voice and video calling on your non VoLTE rom. You can use JioCall with a JioSIM either in the phone or in a JioFi connected to your phone. You can now use your non-VoLTE 4G smart phone to make HD voice and video calls to any landline or mobile number anywhere in the world.
