Is it dangerous to intercept short messages and open them?

Interception is mainly based on SMS content. When sensitive words or industries are involved, it is judged that spam messages belong to interception.

Apple phones don't intercept advertising messages. Android's mobile phone has its own interception system, which will intercept at random, and the probability is very small. Interception software sets keyword interception. For example, advertising words that often appear in recent days will be set as keywords.
