The solution supports two subscription types:
Primary subscription – For use in the home network, will have a higher priority, i.e. the applet will first attempt to logon with the primary subscription before falling back to the secondary subscription.
Secondary subscription – For use while abroad based on the Roaming partner’s agreements.
The subscription switch will be triggered by MCC change as reported by the handset.
This mechanism manages the mandatory parameters required for a standard authentication in a GSM/UMTS network.
