I forgot my unlock code for my samsung blackjack 2 phone how do i unlock my phone?

Hello Friend,
Here is the procedure:
  1. First you’ll need to get your Network Control Key. The Network Control Key is a 8 digits unlock code. There are two paths to get your NCK. You can either call AT&T or ask for it. You may have to ask them to put you through to their tech department. If you’ve never signed up for AT&T’s Service they may not give the code because your not a customer. The other way to get the code is to contact a cell phone unlocking service. They usually charge around $20 to get this code for you.
  2. Once you get the Network Control Key power off the phone.
  3. Remove the SIM card.
  4. Power on the phone back on.
  5. Enter #7465625*638*
  6. Enter Network Control Key.
  7. Press “OK” Soft key, not the Send or OK hard key.
  8. Power off the phone.
  9. Reinsert the new SIM card.
Best Regards,

Unlock att blackjack so i can put my tmobile sim in

On the AT&T Network, to unlock the Blackjack :
  • Power on without SIM
  • Type in #7465625*638*Unlock code# (8 digit unlock code*)
  • Device should say: “Network Lock Deactivated”
  • Phone may automatically reboot

The 8 digit code can be obtained by calling AT&T Technical Support and given the representative the IMEI number. In exchange they will give you the Subsidy Unlock Code.
To obtain the IMEI number press *#06# on your mobile device.

Unlocking problem on blackjack

att just used that as an excuse not to unlock the phone. you can purchase a smartsim card on ebay that will unlock just about any gsm phone including the BJ. You use it in conjunction with your sim and it works great.

The only way that you can get the PIN unlock code is to go to your carriers store and ask them to unlock the SIM card from their admin networks.

It depends on how you've acquired the phone. 1. If you are an AT&T Wireless user and you have the phone on contract, AT&T is legally obligated to give you the unlock codes. Just call AT&T Wireless customer service at 1-800-888-7600 and say you want the unlock codes. Most of the time they can give it to you over the phone. 2. If you purchased the phone second hand, you're basically have to pay someone to unlock it. I'm haven't personally used these services, but they do work for the most part. I suggest two different methods: a. Type in "unlock samsung blackjack" into Google. Pick your favorite provider. b. Type in "unlock blackjack" into ebay, pick someone with a good reputation so you can feel more confident than a random website. It should run you $15-$30. Once you have the unlock code, most of the services will give you instructions, but it's pretty simple with the Blackjack. Just put in your new T-Mobile SIM and a box will tell you to enter the unlock code. Just enter the code at that point and you should be ready to go. Hope that helps!
