JustinRevell No it will not have compatibility with US carrier networks, the UK uses different 5G network nodes to the US, as we are currently phasing out 3G over here. Also, you might not receive specific updates for your region (i.e. Emergency Alerts, Software Updates).
infiniteturnip26 Yeah don’t bother trying, Nothing use Royal Mail / DPD in the UK for shipping, and they would only ship in the UK and not overseas. If they were to use Parcelforce (which has now merged with Royal Mail), then it might be possible to get a UK phone over to the US.
Also, it might cost you more to import it from the UK to the US due to Trump’s 15% tariffs currently in effect.
