When I leave an from an area where I have wifi, and go to an area that I need cell data, my phone frequently doesn't use cell data, unless I go to airplane mode for a few seconds or shut down and restart the phone. I have reset the networks, have the most current updates. Both my wife and I are having this issue and frequently miss texts until we pick up wifi again.

In the area where you have Wi-Fi do you also have cell data turned on, and do you have at least one bar of cellular signal? If the phone loses cell signal it will try periodically check for signal, starting with every few seconds, then going to longer gaps between tries, and as high as 5 minutes between tries. It does this because searching for a signal is very “expensive” in terms of energy use. Switching to airplane mode for a few seconds restarts the search.
Basically, Ican be in the building using wifi no issue, I walk outside have plenty of signal, but cant send a text or check email as my phone is not connecting to cell data until I restart or go airplane for a few.
Yesterday I left my house where i get 1 to 2 bars, after driving for at least 15 minutes, I still didn't have cell data until I airplane mode. This morning, no issues. So it doesn't seem to be the same each time.
I have ordered an Iphone 14 and hope that solves the issue.
Do you have a cellular signal within the building while you are on Wi-Fi? If not, my post above explains what is happening.
I can not say for sure. I believe sometimes, I have had signal, but I do know that some of the time I do not have signal and your explanation makes sense. I will have to explore this theory.
