Can you intercept a short message bombing mobile phone?

I saw a news about people's livelihood the other day, and some of them helped reporters. The reporter helped the help seekers to find the communication company to ask about the situation. The communication company said that it could not be blocked and could only be applied across the board. That is to say, the communication company can help you by canceling the SMS function, and our mobile phone can only choose to receive the number with the address book through the APP.
