here’s how you do it. turn off your phone 1st, then insert a sim card not associated with at&t, then it should ask you to place in the 8 digit code that at&t gave you, then afterwards let it synchronized by itself give atleast a minute or two, then try to call using the new simcard not associated with the at&t network… it should work, because it worked for me…

I have the code and unlocked the phone with my old sim. I changed the sim to a prepaid one and it is still asking for me to unlock the sim, what do you do? I heard you cant use prepaid on blackjack 2 phones, does anyone know if that is true?

With some blackjacks you must have a SIM card from the original carrier and LEAVE it IN the phone during the unlocking. Also, once the phone reports a successful unlock their are sometimes other USER SIM unlocking codes that may be required. These may be the last four digits of the original user’s social or some other 4 digit pin. After unlocking my Blackjack2, I had to download a manual and then figure this out for myself.
