You must obtain BlackBerry Workspaces licenses to enable the BlackBerry Workspaces service for users in your environment. After you purchase the licenses, the BlackBerry Workspaces licenses section is displayed on the Licensing summary screen in the BlackBerry UEM management console. UEM supports SIM and Server licensing models, and you can use licenses from either or both models, depending on your organization's requirements. If your environment uses both SIM and server licences, SIM licenses are always consumed before server licenses. To use SIM licenses, devices must have SIM cards that the wireless service provider has provisioned.
