For at least the last year and a half now, I have had an ongoing issue with phone calls going straight to voicemail but the phone never rings or shows a missed call. I have spent more hours than I can count trying to get help from tech support running all the diagnostic tests and it never goes anywhere, I had to create a voicemail message to let clients know to please leave a message or send a text so that I know they called.
I run two small businesses and this problem is causing real issues. I even traded in my S21 Ultra for an S23+ hoping that a new phone would be the answer but it wasn't, I still miss multiple calls a week. Do better Verizon!
