Will the main card receive the message when the secondary card is charged with traffic?

Whether this situation will receive a message depends on the operator.

The main card and the secondary card can share the traffic in the package, but the traffic used is independent, and the main card will not receive the SMS of the secondary card to recharge the traffic.

The primary card is the primary account of the secondary card, and all consumption information of the secondary card will be managed through the primary card. When the secondary card purchases a traffic packet, the main card will receive a prompt message or notice to facilitate the management and control of consumption.
