So my wife has a Galaxy Note 3. I moved the number over from AT&T. But the phone is prompting me for a "SIM network unlock PIN". Some internet research suggests this is because the phone is locked, which is strange because this phone was unlocked before it got put on the AT&T account. So I figured they re-locked it or something so I go on the website to unlock it and it gets denied. So we go into the AT&T store and they can't help us because they only do unlocks on the site.
We already moved the phone number over so the phone doesn't work at the moment and I just want to get the unlock code for the phone, and AT&T can't be bothered to help so I am wondering if there's another way.
Edit: Also the SIM is a new one we bought from Ting, not the old one.
