Iphone 13 cellular data not working after leaving wi-fi

Hi, I have recently purchased an iphone 13 pro and it is working perfectly except when I leave wi-fi it goes offline. It connects to the cellular nework, can make and receive calls but it cannot receive data.

I can get it working by switching airplane mode on and off but the problem always returns when I leave wi-fi again. I’ve tried restarting but it hasn’t helped.

Is there a more permanent solution I can try?
