Issue Description
Why the Physical Interface Status of a 3G Cellular Interface Is Down?
Solution
If the physical status of a 3G cellular interface (cellular interface) is Down, no 3G link is established and data service has not been transmitted yet. That is, no dialup is triggered or dialup fails on the 3G link.

NOTE:
If no dialup is triggered or dialup fails on a 3G link, the physical interface status is still Down even if a 3G data card (3G modem) is installed.
