I am a Unicom customer. Excuse me: Does Xiamen Mobile have the right to intercept my personal private messages and short messages about business secrets invited by customers? ...

This is not a question of rights. Everyone is annoyed with spam messages, so China Mobile Unicom can only use technical means to block them. If there are sensitive words in the content, it will be considered as spam messages and you can't block them. If you send dozens or hundreds of messages in a row, you also think that you are sending spam messages, which are blocked for you. In fact, it is possible for you to send blessings or product introductions to colleagues or customers in the company. There is no way. Mobile Unicom, the boss of state-owned enterprises, is not to be taunted, and you and I can't waste our energy to sue him in court. . .

Can't change, can only accept. This is the case in China under non-supply management.
