How to set up a black and white list in the mobile phone business hall?

For your convenience, the mobile phone business hall client version 3.0 provides the function of setting a black-and-white list of spam messages interception. After logging in to the mobile phone business hall, click My Unicom > Communication Manager > Set Spam SMS Interception on the homepage, and click the gear icon at the top right of the page to add a black-and-white list. Click "Interception Mode" in the page to set the interception mode. Tips: The iPhone version of the mobile phone business hall does not have this function for the time being.
