Z10 won't unlock after successful code entry

Hey I just got the z10 for att. I got the unlock codes for it and entered them into the settings menu like a good boy. It says network provider and subset are unlocked but it asks for a code when I put in my sim. When I re-enter the code it uses an attempt. HELP

You're probably using the wrong code. If you got the code from a website claiming to be offering free codes, those codes don't work; I tried.

I got it from att. The thing is it said code accepted when I entered it in.
