Single stop reminder is the secondary card stopped by the main card?

Single stop reminder means that the auxiliary card is stopped by the main card.

Single stop reminder means that when the secondary card stops due to the arrears of the main card or other reasons, the operator will send a short message to remind the secondary card users. The secondary card and the primary card are two numbers under the same account, which are interrelated in the operator system. When the main card has problems such as arrears, the operator will send a stop instruction to the secondary card, resulting in the secondary card not being used normally. In this case, the sub-card user will receive SMS notification of single-stop reminder.
