Question: How are predefined animations handled over the air interface in SMS?
Option 1: Only the identification of predefined animations is sent over the air interface.
Option 2: Predefined animations are sent in a compressed form to save bandwidth.
Option 3: The entire animation data for predefined animations is transmitted over the air interface.
Option 4: Predefined animations cannot be sent via SMS; only user-defined or extended animations are allowed.
Explanation: According to specifications, predefined animations are not sent as animation data over the air interface. Instead, only their identification is transmitted, and the corresponding animation is displayed in a manufacturer-specific manner once its position in the Short Message (SM) data is reached, minimizing bandwidth usage for commonly used animations.
