You need to call AT&T customer service and ask for th subsidy unlock code for you phone. I have unlocked two of my phones and my wireless wifi card. Tell them you are going out of the country and want to get another SIM card for use there. They will email you the instructions and the subsidy unlock code within 24 hours. The only requirement is that your account be in good standing and you have had the phone for something like 6 month.

Difference between a power boater and a sailor out on the water: A power boater is going some place special, a sailor is already there.
