Why does Apple's mobile phone only intercept calls and not intercept text messages?

1. Open the telephone interface, click the two small white dots in the upper left corner, and then click the harassment interception.

2. Continue to click the interception rules in the upper right corner, which are divided into call interception and information interception.

3. There are many interception projects that can be started by choosing phone interception, such as intercepting suspected fraudulent calls, intercepting harassing calls, intercepting advertising sales or real estate agents.
