How can I get the MCK code. For a change, those of at&t become those who do not know of the existence of that code.
I bought the phone on ebay when I put my company's sim in it it asks me for the MCK code I called at&t and they don't know about that code. Samsung tells me that they sell unlocked phones and those who block it are the companies that offer cell phone service. Can someone help me how can I get it released? Ah, it is free of contract.
