You should have SIM card installed to apply unlock code.

If you have SIM card installed, you should see ID for SIM card under "SIM Card" screen by Options -> Advanced Options -> SIM Card.

To apply unlock code to your BB8830
Options -> Advanced Options -> SIM Card -> type "mepd" , then type "mep2"
It will ask for "Enter Network MEP Code (10 left):"
From this field , now you can type "unlock" code.
