Question about old device unlock.
Recently I have received an old broken iPhone 4 from a family member and after fixing it I wanted to try using it, but apparently it has a simlock. Turns out it's actually locked to US AT&T Puerto Rico. The phone actually has traveled a long way being passed on from a family member to a family member over the years and now it's currently in Poland.
I've checked out the unlock device section, but even after selecting that I'm not a AT&T customer it still asks for a valid phone number, which I'm not able to provide since I live in Poland.
I've also tried to find some kind of way to contact support but was also unable to find anything else than a phone number (again - I am not in the US, so that won't work), was hoping for an email address or something. The chat bot was also not helpful, asked for human help and it asked me to login to my AT&T account, which I am unable to create since I'm from Poland.
Would it be possible for me to request an unlock for this very old device?
