I've just updated my S24 Ultra this afternoon to UI 6.1.1 and since its updated i cannot connect to a network(States no service), i've taken the sim out and put in my partners phone and it works fine with out issue so its not the sim and my s24 was working this morning.

I've reset the network settings, reset the phone and everything short of a full factory reset as i don't want to lose my data, has any one else experiences this and has a fix?
