I have us unlocked s21 ultra and after the recent update of one ui4 the VOLTE option is not available and iam unable to make calls or receive any messages.
Tried most the troubleshooting steps but no use.
Any help would be appreciated.
I have this exact issue. I have seen several other threads related to this topic. It's an issue with OneUI 4.0 which Samsung needs to fix. However I have not seen any sort of acknowledgement from @Samsung Team so far.
Thank you for your feedback. If you haven’t already, Please update Samsung members app to latest version from galaxy store and send us an error report immediately after experiencing the issue from the Samsung member’s app -> Beta Feedback -> Error Reports to help us debug the issue. We apologize for the inconvenience and appreciate your contribution to the beta program.
