Hacking, or unlocking, a Blackjack II from Samsung is the only way for many users who have the phone but no AT&T service to use the device, as Samsung and AT&T have an exclusivity deal for the Blackjack II in the United States, as of 2009. Hacking the Blackjack II to run on other networks is not difficult and takes a few minutes to complete.
Instructions
1. Contact AT&T and ask for the network control key for your Blackjack II. If you purchased this phone without an AT&T contract, contact a cell phone unlocking service, instead. These services cost about $20, as of 2009, to acquire the control key for your phone, but you cannot hack the Blackjack II without it.
2. Turn off your phone and remove the SIM card from the Blackjack II.
3. Turn the phone back on with the SIM card removed and enter the following code: #7465625*638*
4. Enter your network control key.
5. Press the "OK" soft key. This is not the "Send" button or the "OK" button on your Blackjack II. It is the button that your phone's screen indicates as "OK."
6. Power off your phone and reinsert your SIM card. Power your phone back on to complete the unlocking, or hacking, process.
