iPhone 15 Pro Max purchased in US but used in UK? Is it possible?

Hi everyone, I just pre-ordered the iPhone 15 Pro Max from the US.

I will however go back to the UK a week after the launch and hoping to use my new iPhone there.

I am fully aware of the eSIM only US version, but I am worried if the network bands are different or if it might not work?

I don't mind using just an eSIM but I am worried if there are any essential differences in bandwidth or frequencies that would prevent me from using the iPhone freely in the UK?
