iPhone 14 pro max with a sim card slot

No, it is not possible.

Purchase the device in another country, preferably the country where it would be used.

If you will buy it in the US there is no possibility to buy any iPhone 14 series with a physical sim slot

Not in the USA

Am in Grenada an i want to buy an iphone 14 pro max with sim tray because the country am in does not support eSim as yes.

Is that possible
