Can the incoming call firewall prevent short messages?

Yes, because after the phone number is blacklisted, only blacklisted users will be blocked, and short messages can be received normally.

The general process of adding a mobile phone to the blacklist is as follows.

1, open the phone interface and find "Dial". Other mobile phones may be call records or caller ID.
