Hello,
The default code is 0000. If that doesn't work your carrier should be able to get into your phone. Take the phone with your to your carrier's office when you buy your service, they need the numbers of of it to be able to get into it.

Good Luck,
John

Use the Samsung PC Suite -- get the software here:
For Windows 2000/XP

For Windows Vista
If you've misplaced the PC-connecting cable that should have come with the phone in the box, try connecting to the software via Bluetooth. Of course, you'll have to make sure Bluetooth is on for both the phone and the PC for that.
