Question about Samsung Blackjack SGH-I607 Smartphone
Call at&t customer service and they will help you with that problem.... you have to give them ur IMEI code under the battery and they will give u a code so you can use a tmobile SIM card on any at&t fone

Free unlocking codes are usually worth what you pay. You spend more time looking for the code than it is worth. I suggest you search ebay, where you can usually find unlocking software for a few dollars.
