My number has been blacklisted by 5s mobile phone. Can he get the message?

If the interception of phone calls and SMS messages are set at the same time, the users who send SMS messages from the other party will not receive them;

If only intercepting calls are set and intercepting short messages are not set, then the short message users of the other party can receive them.

Even if the user sets the interception of SMS, it can still be seen in the blacklist record, unless the user sets the blacklist record to be cleared.
