ALL att sims come with a default SIM PIN of "1111"
the software up date uses this to lock the change the PIN and lock the SIM
you do not have to have the Mobley turned on/powered up
the SIM does not have to be in the MObley
You do need the phone number and account info for your Mobley
once you have the PUK, Pin Unlock Key
there are procedures to follow to unlock and protect your SIM
slightly different IF your Sim is not in the mobley and not locked
for locked sims
insert into an UNlocked att compatible phone
enter any random wrong PIN code 3 or 4 tries
NO more
it should ask you for a PUK to let you set a NEW PIN
use that menu to enter your PUK you got from ATT
set a new PIN of your choice for accessing the SIM
you can now remove the SIM and put in any device and use that new PIN you created for device access
IF your SIM is not in the MObley and NOT locked
you do not need the PUK
put the SIM in the ATT unlocked phone and create the SIM lock (your code choice}
goto the SIM mneu and enter the default PIN '1111'
follow the menu prompts and enter a NEW PIN of your choice
so that the SIM has a new PIN code
you can now safely use it in any device

I actually didn't have any hold time. I called 1 (800) 331-0500. When the automated voice came on and asked what it could help me with, I said, "Get a PUK code." The voice said, I can help you with a SIM card, please hold. And it transferred me to the rep who gave me the codes.
