IOS 16.1.1 - iPhone drops both cellular and wifi network randomly

Ok. So as I replied earlier, I reset my network on my iPhone. After 5 days here is my summary:

When I unlock the phone, I have no connection for about the first 2-3 minutes. Although it shows either 5G or LTE, every app gives "could not connect to server" or "no network available". Then after clicking the 'retry' several times:

• • If I am at home, the wifi icon appears in place of LTE or 5G and suddenly my connection is good
  • If I am out, suddenly my cell data starts working correctly

The iPhone stays connected until it locks again, at which time I am back to the beginning of this summary, with no connection.

Is there a way to force a carrier services update? Otherwise, what good is looking at the version? And does the carrier services code affect the phone's ability to connect to Wi-Fi (which I said it is not doing for the first few minutes after it is unlocked)?

So, I have now updated to IOS 16.1.2. I laughed at how this upgrade makes it "more compatible with wireless carriers," as if a phone's primary purpose is to do something other than communicate with wireless carriers. Brilliant stroke of genius to advertise that an upgrade is designed to bring the device closer to actually functioning correctly. But only more and not fully, as me, Swe_Josh, and probably hundreds of thousands around the US found out.

One thing I noticed (I have At&T as my more compliant carrier), is that I now have 5G in lots of places where I only had LTE under 16.0.0 and 16.0.1.

Second, it takes less time for the phone to actually connect to something after unlocking it than it did under 16.0.1. Now, I get to watch the wheel spin for only about a minute before the phone connects and starts to function correctly instead of waiting 2-3 minutes for each of multiple attempts.

But it still does not work correctly. Maybe the Apple IT staff can find some time in their next sprint to get this whopper bug they introduced out of their phone. Maybe not.

But for now, my iPhone 13 is at least closer to being a phone again than it was 3 weeks ago.

I have done the network reset, and then put my cellular and VPN settings back and reconnected to all my wifi devices. We will see how well this fix works. I will reply again in 2 days.
