How Does Robokiller Block Phishing Texts?
Robokiller employs a comprehensive three-layered approach to filter and block unwanted SMS and MMS messages:
-
Block/Allow List: Users can manually add numbers to their Block List, ensuring messages from these senders are directed to the Junk folder. Conversely, numbers on the Allow List are permitted through.
-
Number Reputation: Robokiller assesses incoming messages against a global database of known spam numbers. Messages from numbers with a history of spam activity are automatically blocked.
-
Content Analysis: The app scans message content for scam-related keywords and patterns, enhancing its ability to identify and block phishing attempts.
When a message is flagged as spam, it is moved to the SMS Junk folder on iOS devices or filtered silently on Android devices. Users can review these messages at any time. (support.robokiller.com)
