Finally, can you check the content of the message? I just saw the answer in Baidu. Some websites on the Internet say yes, so it's not a problem to ask the score.

Theoretically, China Mobile and China Unicom can find the content of short messages, but for the purpose of "protecting users' privacy", both claim that they can't find the content. Netcom and Telecom claim that they can only check the long-distance list within three months, but not the local telephone list. In fact, they can also check the local phone list for three years in a row, but it is not open to users. Once it is opened, it will lead to the loss of economic interests of telecom operators, and the lack of protection of users' privacy will lead to legal proceedings and other problems. But now, in order to earn more money, some insiders will secretly check for some people, and if they are found, they will be investigated for legal responsibility.
