Question: What is the primary purpose of including the "X-3GPP-GroupUID" Type in a vCard, as per 3GPP specifications for Contact Manager applications on UICC?
Option 1: To associate a vCard with a specific group defined in the "GroupsDefinition.xml" file.
Option 2: To enable encryption for multimedia elements within the vCard.
Option 3: To facilitate synchronization of vCards across different UE (User Equipment) devices.
Option 4: To indicate the storage capacity allocated for vCards on the UICC.
Explanation: The "X-3GPP-GroupUID" Type is specifically designed to link a vCard with a particular group defined in the "GroupsDefinition.xml" file, enhancing contact management by allowing grouping of contacts. This association enables more organized and efficient contact handling within the Contact Manager application on the UICC (Universal Integrated Circuit Card).
