Your North American Blackberry is most likely "locked" to the service provider you purchased it from. Rogers, Telus, Fido, & Bell do this to keep you locked in to their service, preventing you from using your device on another network. Sure, you could try one of those other unlock services that charge you, but why bother? You can now unlock your Blackberry device for free!
Visit http://www.freemyblackberry.com/freecode.html and get your unlock code e-mailed to you within 24 hours at no cost! This site also provides free instructions on how to enter in the Unlock code and complete the unlock.
Take that Rogers!
