Hello, how can I find historical short messages on the web page?

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).

Specific query SMS list method is as follows:

1, log on to Unicom 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.
