Why do I still receive messages after calling the bank service hotline to block commercial text messages?

Some commercial text messages are not sent by banks, so they cannot be blocked. Set up the link on your phone yourself: Open the phone manager and click on Harassment Blocking in Security Protection. 2. Click the gear logo above to enter the settings page. 3. Select “Intercept Keywords” and enter keywords such as “winning”, “promotion” and “insurance”. Select "Intelligent Interception" as the interception mode, and mobile phone manager running in the background can automatically intercept spam text messages.
