Invalid SIM message appears sometimes Every once in a while I see an Invalid SIM message at the top of my screen (iPhone 8). Any idea what this is? Restarting the phone makes it disappear. Thanks in advance!

Mobile Data Update Failed After restarting my iPhone X as usual, after unlocking it with my passcode, I did not receive the usual prompt to enter the code for my SIM card. What's more is that no service is found, the bars at the top keep looping/trying to search for service. After a while, a message popped up stating "Mobile Data Update Failed". When checking under Settings -> Mobile Data, it informs me that an update is required to use mobile data. After restarting, the situation is unchanged (again no SIM pin prompt, either) and this time, checking under Settings -> Mobile Data, the page is entirely blank. There are no toggles, no sub-menues etc. Just like with this user https://discussions.apple.com/thread/251288419 Following the link under "learn more", I conducted a full re-install of iOS 15.3 via iTunes on my PC. The issue persists. When restarting the phone without a SIM card in the tray, the issue persists unchanged. When inserting the SIM card into another device, the SIM card is recognized and the other device can be used normally. I would appreciate any input!

No SIM card when SIM card is in I’ve betting getting a no sim error pop up on my iPhone 8 recently even when my SIM card is in. It disconnects me from service before reconnecting a minute or two after. Is anyone else getting this?
