iPhone keeps saying "no sim available" after IOS 16.5 update.

I recently updated my phone about 3-4 days ago to the 16.5 update. Yesterday, may 26, I got a pop-up that said “No Sim Available” and had to press ok to clear. My phone went to SOS mode and I had to restart my phone. This morning I check my phone from waking up and my phone is back on SOS mode. So while I showered I turned my phone off and then powered it back on when I got out. I haven’t had this happen before, except when my SIM card was damaged when I was with Verizon. But that was over 7 years ago. Is anyone else having this problem after the update?

1 hour ago, everyone’s iPhones at work suddenly said “NO SIM” all at the same time. Different carriers, different models of phones. Some personal phones, some business phones centrally managed. The whole building had to manually reboot their phones to get the devices back to normal. What is up with this?
