Question: In 3GPP-compliant SMS encoding, how are the most significant decimal digits represented in an octet-represented field?
Option 1: The most significant decimal digits are always in the last octets of the field.
Option 2: Each octet represents a binary value, with significance determined by the receiving UE's (User Equipment) configuration.
Option 3: The most significant decimal digits are contained in the octets with the lowest octet numbers within the field.
Option 4: Octet representation is irrelevant to the significance of decimal digits in SMS encoding.
Explanation: This question assesses understanding of how data is structured in SMS messages according to 3GPP standards. The correct answer reflects the specified rule that in an octet-represented field, the most significant decimal digits are stored in the octets with the lowest octet numbers, ensuring consistent decoding across compliant devices.
