Abstract
A method and apparatus are provided for a subsidizing service provider entity to personalize a subscriber device to ensure the subscriber device cannot be used in a network of a different service provider entity. As the service provider entity subsidizes the subscriber device, it desires to ensure that subscriber device is personalized such that the subscriber device may operate only in its network and not a network of a different service provider entity. The subscriber device is pre-configured with a plurality of provider-specific and/or unassociated root certificates by the manufacturer of the subscriber device. A communication service is established between the service provider entity and the subscriber device allowing for the mutual authentication of the subscriber device and the service provider entity. After mutual authentication, the service provider entity sends a command to the subscriber device to disable/delete some/all root certificates that are unassociated with the service provider entity.
