Because the other party is cheating, can I go to the mobile company to check the content of the other party's short message?

If you submit a written application to the court, whether you can testify depends on whether your daughter has corresponding civil capacity and whether you know the legal consequences of testifying. Whether it's China Mobile or China Unicom, whether it's its own card or someone else's card, China Unicom, the mobile company, does not provide content inquiry, unless it is inquired by the telecom insiders of the Public Security Bureau. I found an insider of the public security bureau to help me find it through the introduction of netizens, and spent some money. I can ask him for help if necessary.
