Question: What does a "Data Connection Status" value of '00' indicate in the context of a USIM Application Toolkit (USAT), as per 3GPP specifications for various radio access networks (RANs)?
Option 1: The data connection is pending, awaiting further action from the device.
Option 2: The network has rejected the data connection request due to insufficient resources.
Option 3: The device has deactivated the data connection upon user request.
Option 4: The data connection has been successfully established, accepted by the network and completed by the device.
Explanation: According to 3GPP specifications for various RANs, a "Data Connection Status" value of '00' signifies that the data connection request has been successfully processed. This means the network has accepted the request, and from the device’s perspective, the necessary setup for the data connection has been completed, enabling data transfer.
