Can SMS be blocked?

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.
