We are still in the process of improving our SMS Spam Protection. Not every number is being blocked, but as long as you add the number into RoboKiller's block list and SMS filtering is enabled in your Settings, we'll be able to continue to analyze these messages that are coming in and block them if we recognize that they're malicious.
You can add numbers into your blocked list in RoboKiller by doing the following:
- Open the RoboKiller app
- Go into the Block/Allow tab in the app
- Tap "Allow" in the top right corner
- Tap "Add"
- Enter the phone number you'd like to add
- Tap "Save"
- You will have the option to label the number as you choose.
You can enable SMS filtering by going to Settings > Messages > Unknown and Spam.
