After Apple's mobile phone was intercepted, why was the SMS intercepted?

Apple's mobile phone will not automatically intercept short messages after intercepting incoming calls. Steps for Apple's mobile phone to block incoming calls and text messages:

The blacklist screening function has been added in the new system. Click Settings, select Information, and click the Blacklist function option. Select Add, and all your contacts will pop up automatically. Select the contact you want to block, and you will not receive calls, messages or FaceTime calls from the blacklisted contacts.

If you want to cancel the restriction that someone is blacklisted due to misoperation, you can click "Edit" in the blacklist and then click the red button to unblock it.

If you want to intercept a strange phone number, you can find the phone number you want to intercept in the recent call records, then click the exclamation point to enter the detailed page and choose to intercept this incoming call number. After blocking this number, you will not be blacklisted for contacts, text messages and FaceTime calls.

If you use security interception software, ordinary short messages that intercept calls will also be regarded as spam messages.
