Cannot make or receive calls
For the last 3 or 4 days, I suddenly cannot make or receive calls. People trying to call me immediately go to voicemail. And when I call others, as soon as I hit the phone button to make the call, I immediately get the message "call ended". This is with my regular number tied to my AT&T sim as well as my google voice number I use for work. Even when I try to dial in to voicemail, I am disconnected immediately. I tried restarting my phone, updating software, moving to different spots of my house and work and on the road, turning the airplane mode on/off, and looking through other articles to try to solve the problem. Calling 911 works (I tried that).
I'm using a Samsung Galaxy Note 10+. Everything else about the phone is working smoothly.
