Buy iPhone 14 and iPhone 14 Plus - Apple

Phones purchased directly from Apple w/o a carrier affiliation are unlocked.

Other considerations:

Note that while they are “world-wide” phones, their frequency bands might not exactly line-up with all that is available from carriers in other regions.

Obtaining warranty repair outside the U.S. will also be problematic.

iPhone 14s sold in U.S. can’t accept nanoSIMs.

It’s always best to purchase an iPhone marketed in the region of it’s primary use.

"But i want to buy 13 pro max, it’s not available on the apple website".

Yes they are.

Understand.

And you are certainly free to do so.

But it should be an informed decision;

with full understanding of the potential issues which might - but often never do - arise.

The iPhone 13 Pro Max is discontinued. Apple no longer sells it.
