I want to buy a i phone 12 pro max . Is this phone unlocked?

That would depend on:

Exactly where are you hoping to purchase?

If an unlocked version is offered on that site.

If you select the unlocked version.

NOTE: Apple will not ship outside the country where the device was ordered.

Apple sells unlocked iPhones if you select the "Sim Free" version on their website, or in a store.

Outside of that, you would need to tell the people of wherever you are purchasing from you want an unlocked version if there is one available. There may not be depending on where you purchase.
