Older version of iOS, Apple only allows filtering for iMessenger, now iOS 11 allows filtering for SMS/MMS also. Now in Messenger App, Apple adds a new tab named “SMS Junk” that stores your Junks.
The new iOS App named “Junk Filter” was developed based on this new feature of iOS 11 to helps you to filter your incoming SMS/MMS messages into Junk or Inbox. Its user interface is friendly & easy to use, there’re 2 methods of filter: by senders & keywords.
• Filter by senders: All messages that come from those senders will be filtered as Junk.
• Filter by keywords: All messages that contain junk keywords will be filtered as Junk.
