Sim not working In new phone

[Fat_fingers]

Hi I’m upgrading from a iPhone pro max to a iPhone 14 Pro Max and I’ve just had a new sim but it dose not work in my new phone it has been unlocked do I need to download new carrier settings ? If I put my sim back in my old phone it works fine

Just use your old sim

Or do a sim swap
