What should China Unicom do if it always receives spam messages?

The method of intercepting spam messages is as follows: 1. The number at the beginning of 106: the number can be recorded and blocked for 100 10 manual customer service; 2. Android mobile phone users can log in to the Android version of the mobile phone business hall client, click customer service > spam report, and enter the spam report page to report spam messages; 3. There is no number, but there is a link URL: you can turn off the service/push information through your mobile phone, so it is recommended to pay attention.
