I use the primary card in other provinces and my mother uses the secondary card at home. Why does mom's health certificate turn red?

The secondary card cannot change the location information of the primary card. The main card user is outside the province and has a driving record in a high-risk area. The secondary card user cannot change the location information of the main card in the standardized management area, so the secondary card user becomes red team. Primary and secondary cards refer to the sales mode that China Telecom provides users with a primary card and a secondary card at the same time.
