so… Ive been trying this too. after checking many blogs and posts I think I see the missing detail… I found it on this blog…. it reads…
Just found a thread on AT&T about unlocking the BJ II. It says that the problem with the instructions you were sent is that one of the steps says that you should remove the SIM card.

The post says that that is the error – follow the instructions exactly as they are BUT DON’T REMOVE THE SIM CARD.

Here’s the exact post:

I just had an issue with using an AT&T provided (via international customer support) subsidy unlock code on the BJ2. The intructions provided via email or over the phone tell you to remove the SIM card and follow the instructions. This does NOT work, and results in a SIM Failure message. After about an hour on the phone through AT&T and then into Samsung technical support level 2, I found out that the instructions should be followed as provided, but with the AT&T SIM installed. The tech support person at Samsung says that he has asked AT&T to change the instructions a number of times, but it appears that they have not been changed. He said that sometimes it just takes a while to get through the system…………

SO THE KICKER… wITH THE at&t SIM INSTALLED….MAN..I hope this works

For the blackjack II I617 you will need a sim not an ATT sim but a sim in the phone for the unlock process.

I called ATT 1-800-331-0500 and give them the IMEI number of the phone.

They give me the unlock code which was eight number.

I typed in #7465625*638* and entered the eight code number the ATT rep give me and that was it. The phone is now unlocked.

Thank you all that provide the helpful advice. I hope this helps someone.

regarding blackjack 2, i was on the phone with 2 ATT CSR b/c I could not unlock the phone for the life of me. as instructed by them, i confirmed that my SIM card was out. numerous times it failed and failed. i got fed up with them and searched online.

NOTE TO EVERYONE: LEAVE THE SIM CARD IN WHEN YOU UNLOCK WITH YOUR 8 DIGIT CODE.

booya.

Corrected: For the Blackjack II…you need to leave the SIM in the unit…but the code sequence works great.

the best thing to do is to get a t mobile sim in the phone and turn it on! then when it asks for the code put in #746625*638* followed by the nck which is different for every phone then put that after the other code and hit ok
your good to go from there
