They sell these already unlocked on ebay by the hundreds. If you're attached to the one you have, you can find a cell phone store that will unlock it for you by visiting unlocktotalk.com to find a local store or send it in to unlocktotalk.com. They have a CDMA unlock mail-in service if there is not a local cell phone "flashing" store which provides this service in your area that can reprogram your phone to work with the new CDMA service of your choice. I suggest you log on to www.unlocktotalk.com to get details. It only costs about $20 and it is 100% legal. They openly advertise that they can unlock CDMA cell phones (or GSM-in a separate section of their website- if you need them to.)

To unlock a Samsung turn the phone off take the sim card and type the following code *#pw+15853649247w# .
Java status code: #*53696# (Samsung X600) If you want to unlock your phone put a sim from another company then type *#9998*3323# it will reset your phone. Push exit and then push 7, it will reset again. Put your other sim in and it will say sim lock, type in 00000000 then it should be unlocked. Type in *0141# then the green call batton and it's unlocked to all networks. This code may not work on the older phones and some of the newer phones. If it doesn't work you will have to reset your phone without a sim in it by typing *#2767*2878# or *#9998*3855# (not tested)

When you place a new or a existing SIM card from another phone provider into your mobile phone and it asks for a Security Code then :-
This phone is locked to the original mobile phone provider. You need to contact this mobile provider to ask for the unlock code (Security Code) for this phone. You need to provide proof of ownership etc and the phone's unique IMEI number which is located inside the phone under the battery. They use this number to generate the unlock code for your phone.
They should provide you with instructions on how to enter this code into the phone.
Once you unlock the phone, then you can insert a new SIM card in this phone or sign up with another phone provider using this phone.
You could ring the phone provider and ask for the unlock security code because you are going overseas and wish to use your phone with a prepaid SIM card from another country. This may be a free service.
The other way to get your phone unlock is to use a phone unlocking company on the Internet, they usually charge a couple of Dollars for their services. Use Google and search for "Security unlocking code” companies in your area.
