Internet not restoring after leaving no-service area on iPhone 16 Pro

When I go to a place where there is no mobile Internet, it disappears on my phone. And when I leave this place, it does not appear again. I just need to reboot the phone for it to appear again. How can I fix this?

Rudegar is correct. When you go to a location that has no cellular signal your device tries to find one every few seconds, then it extends the intervals between tries for a couple of minutes, then extends the intervals between tries to 5 minutes to avoid running down the battery (cellular network access uses huge amounts of energy, especially when there is a weak signal or no signal). Switching on Airplane mode for a few seconds, then turning it off will start the network search over. Also, waiting 5 minutes will also work, but who wants to wait 5 minutes in these busy times? 😏
