So I have an S23 Ultra and its been fine for a while but recently it started to just not have cellular sometimes, it will be on full bars Ultra Wideband 5G and then 2 seconds later have absolutely no cellular whatsover. I know it's not a carrier issue because I have tested this with multiple different carriers with the same problem still occuring. I also ran Samsung's antenna diagnostic and it says there are no problems. Wi-fi is also still completely normal, just cellular.
