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.
okay what if i dont have at&t i have this blackjack phone and i need and need all the codes you would need to unlock this phone if anyone could help please email me at lewichic22@yahoo.com
Hi cingular is the best way to unlock ur phone once you have an contract and your bill is not 90 days due. I got my samsung blackjack unlock last night and it is working perfect. When u are calling cingular make sure have ur IMEI number handy to give them so the can give u the unlock code. The number is
(916) 843-4685
First you take out the sim card
second power back on the phone with out an sim card
third enter this code #7465625*638*
after that the screen will appear and it will say no sim
power the phone off then put back in another sim card carrier
then enter the unlock code cingular gives you
then enter #
then enter send
wait for couple minutes then the phone should be unlock
