AT&T unlock code incorrect

There are specific requirements that need to be completed before a device can be unlocked from our network, mrvmrvmrv.

Currently, the only way to unlock your device is to have the original device owner to release it from their account. These details are shared at our Device Unlock Eligibility Requirements.

When it comes to purchasing a phone from a non-AT&T authorized seller like eBay, there are a few helpful tips to consider before making the purchase. We invite you to view these details under eBay & Non-AT&T Purchases when you visit our AT&T Device Unlock Help - Solutions & FAQs.

We hope this information helps. Thank you for reaching out to us.

So you're basically saying that unlock code doesn't work because the phone is active on somebody elses's account? But it doesn't make sense because what if the person who owns the account requested it, he or she would have been given the same code. 

Or are you saying that AT&T somehow can see that another person has the code and unlocking, and thus somehow prevents the phone from being unlocked, even with the right code?

at&t only has the code the manufacturer of the phone supplies if its a wrong code contact the phone manufacturer 

Thank you, I will try that.

I did online chat and called Samsung, they basically told me they don't know anything, they don't have any unlock codes, and it's a carrier problem.

So, what do I do now???
