hours. 0 means no periodic restart is enabled. Restarting
"Smart Roaming" will re-search for available carrier networks
and reset the current status, because searching for available
carrier networks takes a long time, and restarting may take 3
to 5 minutes.
Set the time point for restarting "Smart Roaming" every day,
the format is HH:MM (24-hour clock). When this item is empty,
it means shutting down and restarting.
