Welcome to the Support Community!
I would recommend having your sister contact her wireless service provider first to make sure her BlackBerry 8530 smartphone has been unlocked for use on another network. You may also want to reach out to your wireless service provider just to verify that they will support this. This KB article should provide more information. "Changing the service provider or network" http://bbry.lv/VkbQQo
Let me know if this helps.
