The examples provided herein relate to digital rights management keys that allow for the presentation of content on output devices of a content presentation device. The examples describe subscriber-specific digital rights management keys that are provided to a subscriber by a mobile network operator instead of a device manufacturer. The digital rights management keys are associated with the subscriber account maintained by the mobile network operator. As a result, the mobile network operator provides the capability to transfer the digital rights management keys between multiple devices because the digital rights management keys are subscriber-specific instead of device-specific.
