 How to enter my Unlock Code on a Cingular BlackJack Cell Phone?
Insert Non - Allowed SIM Card (a SIM Card that the phone does not usually accept) and enter Unlock Codes when prompted
NOTE: If you are unable to connect to service provider or unable to make outgoing 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:

- Enter: *#1546792*#
- Select Option 3, Network & Call Settings.
- Select option 5, Network Mode.
