Question: What is the primary purpose of using 3GPP-specific vCard Types in a Contact Manager for 3GPP UICC applications?
Option 1: To associate additional multimedia elements (e.g., ring tone, voice tag, video) and/or store extra contact info (e.g., SIP URI, TEL URI) with a vCard.
Option 2: To reduce the storage capacity required for each contact entry in the UICC.
Option 3: To enhance the security of sensitive information stored within the vCard.
Option 4: To ensure backward compatibility with non-3GPP compliant devices.
Explanation: The correct answer highlights the main advantage of utilizing 3GPP-specific vCard Types, enriching the contact's information with additional multimedia elements and/or supplementary contact details, enhancing user experience by providing more comprehensive and accessible contact information directly from the vCard.
