Add mobile phone blacklist and use third-party software.

1. Add mobile phone blacklist: Add the phone number of the credit card center to the blacklist by adding contacts. In this way, when the phone number comes in again, the phone will automatically block it.

2. Use third-party software: such as 360 Mobile Guard. The software can set blacklists, whitelists and interception rules, etc., and add phone numbers you do not want to answer to the blacklist.
