How to block spam SMS numbers

How to turn off the screen of spam messages? Can be set to black. Just black out this number directly, and then you can receive text messages as usual. His information will appear in your blacklist, that is, the blacklist information box, but you can also set this information in the blacklist to clear all his information. Hacking can avoid being disturbed by his ringtone or SMS reminder, but his phone call records and information sending records will be seen in the blacklist mailbox. There is no radical way.
