I think you have to unlock your phone for the SIM card to work. I don't have any links for that, but I'm sure if you ask around you can find a local shop to assist.

You can unlock blackberry curve 8300 without knowing your password, but it will erased all your data. If you want doing in that way, just keep enter 2 more wrong password again and your blackberry will be autoreseting and you can setup new password. That's the only way to unlock blackberry password.
