Can the Iphone 14 use an actual sim?

iPhone 14’s sold in the United States do not have a SIM card tray and no way to add one. They are Esim only.

iphone 14’s sold outside of the United States have an Esim and physical SIM card.

Not an iPhone 14 that is for the US market. They have eSIM only. iPhones designed for other markets have the ability for a physical SIM. All of the carriers in the US market support eSIMs.

Anywhere outside of the USA

Might be important to note that the warranty on an iPhone purchased outside the U.S. is not good in the U.S.
