Currently Jio has already launched 5g with carrier aggregation and VoNR. However, not a single Samsung device supports Jio 5g+ and VoNR for Jio in India. Not even S23 Ultra. Whereas many budget devices from other brands are providing this feature.
Thank you for participating in the Samsung Developer Forum. However, this is not the correct forum for end product bug reports, questions or concerns. This forum is for 3rd party developer issues.
I would recommend you use the Samsung Members App for feedback
go to https://www.samsung.com and depending on your location
either → Click on Explore Tab → Click on Community
Scroll all the way down to the bottom of the page and under support is a link to the community
Because end user questions disrupt developer discussion this thread will be removed soon.
