This seems to be the multimillion dollar question for Blackberrys and here is how this works.
There is no "magical"code for all BB's
Each Blackberry is item specific based on your IMEI which is located on the inside of your battery compartment.
Your best bet is to go to eBay or similiar and find your blackberry and look for the cheapest unlocking program. AT that point you will be able open your Blackberry.

SOURCE: Invalid sim

1. (easyer way) When I got my Blackberry, I had to put it in a couple of times for it to work.

2. Buy a new sim card.
If this does not work, then check to see if it is unlocked.
