After handling the local one-card multi-number service, how to set the SMS rejection of the secondary number?

When it is inconvenient for users to receive short messages with minor numbers, they can send short messages SZDXKF to 1000 1 through the main number, and set the minor number to the short message rejection state. When the minor number is in the SMS rejection state, the user can also set the SMS receiving state by sending SMS SZDXGB to 1000 1 through the major number. The short message off state of the secondary number does not affect the user to use the secondary number as the caller to send short messages. "Local one card and two numbers optional package (private connection service)" is launched for prepaid/post-paid Tianyi mobile phone users who have been online for 30 days or more. The user already has the Tianyi number as the main number. On the basis of not changing the phone and card, they can apply for a local network Tianyi number as a secondary number, which only provides voice and SMS functions.
