There is no cost for the secondary card of the mobile phone card to send text messages. What happened?

Hello, I hope my answer can help you.

In the first case, because the main card is in arrears, the secondary card has no charge, so you can't send short messages (the secondary card and the main card enjoy the same package at the same time).

The second situation: because the number of the secondary card is restricted to send short messages, you mistakenly think that the secondary card is free. Please call manual customer service for details.
