Can the primary card park the secondary card?

You can park the secondary card. There are personal accounts and family account who need to stop the secondary card. The main card in the main and secondary card package can handle downtime maintenance and loss reporting, but it can't handle downtime maintenance. The main and secondary cards can put forward unbinding downtime maintenance, but they can't handle downtime maintenance. The secondary card cannot handle the traffic package separately, and the primary card and the secondary card use the traffic in the package.
