BlackJack
ATTENTION: If your SIM has a PIN, please remove the PIN code before inserting it into your BlackJack cell phone. You are the only person who knows the PIN as you set it yourself as a security measure for your SIM card, it has nothing to do with removing the network restriction (unlocking of your phone).
Step Action
1 Insert a SIM card from another network into device
2 Power on the device
- Wait approximately 30 seconds until the SIMLock application appears (the delay may be longer if the user has already attempted an unlock with the wrong code)
3 Enter the unlock code in the blank field
4 Press Ok
- If the unlock code is incorrect, an error dialog will appear. After pressing Ok on this dialog, the user has to re-enter the unlock code after delays
- If the unlock code is correct, a success dialog will appear.
5 Press Ok
- The device is now unlocked and should continue booting
Troubleshooting for Blackjack signal problem
NOTE: If you are using an activated and active SIM card and unable to connect to service provider or unable to make out going calls or receive messages, this has nothing to do with your phone being locked or not, you need to force the BlackJack to change to GSM mode, this can be done as follows:
Power on your Phone
Enter *#1546792*#
Select Option 3 Network & Call Settings
Select option 5 Network Mode
Select GSM
