How to keep Unicom from sending spam?

The number at the beginning of 1. 106: Give it to Unicom's manual customer service to record the number and block it;

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. I suggest you pay attention to it.
