China Telecom's family mobile phone package is charged by the main card, but not by the auxiliary card. What's the matter?

As far as I know, the main and auxiliary cards of China Telecom's home mobile phone package share the same account balance. If the primary card has a phone bill and the secondary card has no phone bill, it may be caused by the following reasons:

1. Uneven distribution of account balance: when the package was launched, the account balance was not reasonably distributed to the main and secondary cards, resulting in insufficient balance of the secondary cards.

2. The usage of the secondary card exceeds the traffic and call duration included in the package: the usage of the secondary card exceeding the package will generate additional charges, which will be deducted from the balance of the secondary card account.

3. Other unknown reasons: Sometimes, abnormal deduction may be caused by system errors or other unknown reasons. If the problem still exists, it is suggested to contact the customer service of China Telecom for inquiry and handling.

If the above suggestions can't solve your problem, I suggest you contact the customer service of China Telecom directly for more detailed information and help.
