Operators can automatically intercept pornographic MMS.

After the three major operators run the inter-network spam message linkage processing platform, they have successively launched the self-blocking service of mobile phone spam messages. According to the operator's regulations, users can blacklist the numbers that need to be filtered to prevent spam messages. Some operators also stipulate that users can set the time when spam messages need to be filtered, for example, they can set messages sent late at night to refuse to receive.
