French microprocessor cards provider Axalto has launched 'SIM on the Go', a SIM-based solution that allows portability of protected multimedia content. With SIM on the Go, content rights are managed by the SIM card so when subscribers upgrade to a new handset, they can instantly use previously purchased services.

Digital rights are typically tied to mobile devices, so when subscribers change devices they can no longer use the services they have paid for.

With SIM on the Go using the SIM as the digital rights manager, users can change their SIM cards from one phone into another to transfer their rights to a new device. SIM on the Go enables the operator to back-up the user's rights over-the-air. Therefore, subscribers can retrieve access to their data even when the handset is lost or stolen. The operator issues them with a new SIM card containing the same rights, and they can restore their content.

This can turn the SIM into an enabler for music and video portability. Co-developed with Beep Science, a provider of mobile digital rights management software, the solution is compliant with the Open Mobile Alliance standard - OMA DRM 2.0 - to enable interoperability between devices.
