All map programs for Blackberry currently need a data plan for them to work. For security purposes BB does not allow for program data to be stored on a media card therefore all map data is stored on the web and is streamed to the BB as needed. It's highly recommended to have an unlimited data plan when using mapping services.
I must also note that ATT has BBMaps blocked since they want you to use a different application for LBS. Do a simple search on Blackberry Maps on ATT and you should find a solution to getting the program to load on your phone, if you have not already done so.
