1. Turn off your phone, put in a SIM of a provider that it is NOT LOCKED (difference company's SIM card) to, and turn it back on. 2. At the wrong card message, type *#9998*3323#. A message will pop up telling you to press exit, so hit the right soft key. Choose number 7 . Your phone will reboot and your SIM will work. 3. Type *0141# and then hit call. This will give you a message saying your phone is personalized. 4. Power down your phone and insert a SIM card other(another company) than the one that is in it. Then power back up your phone. 5. At the SIM pass code prompt type 00000000, that is 8 zeroes. So that will totally UNLOCK your phone. if let me know if it works or not
