Orden an iPhone from a different country and send it to the USA

If the company that sells the iPhone can ship the device to the US, then there should be no problems using an iPhone 14 Plus with a physical SIM card in the US.

However, be aware of the warranty on your unit and customs regulations. I don't know those rules.

It is always best to buy a phone in the country where you plan to use it. The warranty is only good in the country of purchase and the phone will connect to cellular networks more easily.
