Question: When a Mobile Equipment (ME) is instructed to provide location information via an NMEA sentence by a Universal Integrated Circuit Card (UICC), and no Preferred NMEA sentence is specified, what should the ME do according to 3GPP standards for USIM Application Toolkit?
Option 1: The ME should default to using a proprietary NMEA format defined by the device manufacturer.
Option 2: The ME should select one of the standard NMEA sentences for location information transmission.
Option 3: The ME must prompt the user to choose an NMEA sentence from all available options on the device.
Option 4: The ME will not transmit any location information until a Preferred NMEA sentence is specified by the UICC.
Explanation: According to the USIM Application Toolkit standards, if no Preferred NMEA sentence is indicated by the UICC for geographical location parameters, the ME should fall back to using one of the standard NMEA sentences. This ensures consistency and interoperability in location information transmission across different devices and networks, highlighting the importance of standardized protocols in telecom operations.
