SIM network unlock pin

Hi

 

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.

 

Thanks

 

Paulo

Re: SIM network unlock pin

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