Is the SMS notification of telecom charges sent to the main card or the auxiliary card?

Mastercard.

For telecom master and slave card packages, bill SMS is generally only sent to the master card, and the slave card does not receive SMS reminders of arrears.

Although the main card and the auxiliary card of telecom mobile phone are bound to enjoy the package, the communication between the two cards is independent and does not affect each other.
