I have been using samsung note 9 enable VOLTE and all was good. But yesterday i went to do software update, the update is dated July 2022, but i didn't do it until now.
After update, I can't use volte anymore on my note 9. The option is not there anymore under settings, so I can't make calls now. Can anyone help? I don't know what to do. I remember i did change the apn previously to resolve volte issue.
But now i change to shwap, volte didn't appear
Really appreciate any advice or help. Thank you
