I just got a prepaid SIM card from an ATT store, but when I put into my phone (LG optimus G, not an att phone, but unlocked). I get the following message "SIM network unlock PIN". How can I get the PIN? I called 800.331.0500 but I cannot get a human to answer.

Are you sure the phone is fully unlocked? Do any other AT&T SIM cards (like postpaid ones) work in it?
