Iphone 14 pro max No network after switching off airplane mode

Hi! Whenever i am switching the airplane mode on and then off my iphone 14 pro max is showing no signal even if the automatic network selection is on. Even if i go to the cellular network option and manually select my service provider from the list of networks manually, still no service is shown. The only solution is to do a hard reboot evry time i switch on and off the airplane mode. I have tried all options found on the web like resetting network settings, turning off and on the roaming , cellular data etc. and all this in a known good coverage area of my service provider. Please help.
