Subscriber data used for access includes a device identifier for the device and a module identifier for a removable module coupled to the device. The device and removable module respectively have credentials for different types of networks. The device and module identifiers are associated with previously stored information for a subscriber account associated with the device. The device is authorized to access the first type of network based on the stored association and is granted authorization only when subscriber data received from the device for subsequent access requests includes module identifier information matching the module identifier stored in association with the device identifier."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Enabling portability of credentials across dual mode devices","description":"A method is presented for enabling a dual-mode mobile device to access different networks.
