How can I know the short message record with someone?

The operator's business hall (note that it is not the cooperation hall) will have a special bill inquiry machine, which can log in with mobile phone and service password to find the time and contact person of SMS. The specific content will not be provided to you, because it belongs to customer privacy, and the policy explicitly prohibits it. Of course, it does not rule out that some abnormal channels can be obtained. If your content is very important and cannot be copied or queried by the other party, you can find some abnormal ways on the Internet. ...

By the way, the SMS records (including content) of operators are kept on provincial servers, and the average time is 24 months.
