Same exact problem as this thread: Not Receiving calls and delayed text messages
Started happening 6 months ago. I've tried everything on my phone. Phone model is: S7 Edge (SM-G935F)
Why was the other thread locked? So many are having same exact issues.
The solution provided does not help at all.
Randomly I will not receive calls when I have full bars. It doesn't show up as a missed call or anything. The person will message me on another messenger and when I call them back I usually get a bunch of text messages time-stamped from the past hour that I have also missed.
I will also randomly receive voicemails with no missed calls indicating that again, I've missed a call but it does not show up in my notifications .
I've tried all the resetting everything on my phone, I've disabled wifi calling and volte but the problem persists. Has anyone experienced this and had it fixed?

Thanks for clarifying. If this is intermittent, I do not believe it to be a device issue. The randomness of it suggests signal fluctuation as signal is not always consistent. The best way to address this issue would be with our over the phone team of experts folks who will be able to collect specific examples from you and open an engineering service ticket.
