I noticed early Monday morning that I was not receiving phone calls, but I would get a voicemail alert. I also noticed later that day that email was not syncing (Exchange or Gmail) and I would get all my text messages at once, some almost an hour after they were sent. I turned off and back on and it seemed to fix the issue. Fast forward to today, my wife text me asking why everything was going to voicemail. It was not allowing calls to go through again, sending everyone straight to voicemail after two rings on their end, but my phone never rang. Anyone else experiencing this issue?
