Hello, I am very happy to answer this question for you. The main credit card and the secondary card cannot receive text messages, but the secondary card can receive text messages from the secondary card. The main card can receive text messages from the secondary card. To know the consumption status of the supplementary card. Since the limit of the supplementary card is specified by the main cardholder, the main card can generally know the consumption status of the supplementary card. If you cannot receive it, it means that the SMS function of the main card has been turned off or the card has been modified. , use the SMS center number of the mobile phone so that the main card cannot receive the information from the secondary card. You can go to the bank in time to handle the operation. I hope my answer can help you, thank you
