Carrier locked iPhone 14 Plus
I bought a second hand iPhone 14 Plus from a private seller in Poland(my country of residence). It turns out the phone is carrier locked by AT&T and when I tried to submit an unlock request it turned out it has not been fully paid off, therefore I can't unlock it there. Is there another way to unlock it or am I stuck with a non-functional phone and a feeling of shame? The phone is not blacklisted btw.
