My T-mobile Note 10 + 5G since after the last update, every time I'm on wifi when someone calls, phone said unable to reach or go straight to voicemail. No issues when I'm on cellular data, I'd like to know if nobody else's have the same issue.
I would try turning off wifi calling to see if the problem still persists.. either way wifi calling should not be an issue. If wifi calling is something you want enabled then you might need to factory reset your phone after backing up all of your content. It will start the phone off fresh as new and could possibly fix the problem. Let me know if this helps.
