I want to see a detailed list of my messages. My classmate said that you can check it online. How should I check? Can you find the content of the message?

Unicom online business hall can query the SMS list, but only the SMS number, not the SMS content, and only the last 5+ 1 month (including ***6 months of the current month). The specific method for querying the short message list is as follows: 1. Log in to Unicom's online business hall www.10010.com; 2. Click Telephone Fee Inquiry-Bill Inquiry-Detailed Bill Inquiry on the left; 3. After entering the page, select the schedule type and time to query, and then click the "Query" button.
