I found the message of 20 16 1.3, my message record.

If you are a Unicom user, you can view the detailed list of SMS and MMS messages in the past six months (including the current month) through the following channels:

1. Log in to the online business hall, and click phone bill query > bill query > detailed list query > SMS MMS detailed list;

2. After logging in to the mobile phone business hall client, click Service > Query > Details Query > SMS MMS Details;

3. Log in to the mobile phone business hall and click Query > Details Query > SMS MMS Details.

In addition to the above methods, you can also go directly to the local Unicom's own business hall to inquire about the details of your SMS and MMS.
