Can the main card see the SMS of the secondary card?

The main card can see the short message of the secondary card.

According to the official explanation of China Mobile, the relationship between the primary card and the secondary card is * * * account sharing, and the primary card can view and manage the communication records and short messages of the secondary card. This is because the main card and the auxiliary card use the same account, so the main card can view the short message content of the auxiliary card by logging in the account or using related mobile phone applications.
