How do I access my puk code?

Perhaps if you've not tried to much, the iPhone may not be locked out, yet?
While I'm no expert, so far my iPhone just works; at least most ways, still.
Some ideas & the like, may be found online via search results, duckduckgo, etc.

This goes through ideas; arrives at P.U.K. codes, eventually. Says good & bad.
There are general search results, with other leads; they may be found here:

The related article above your post, mentions 'Personal.Unlocking.Key' barely.
