Unwanted SMS messages, often from unknown numbers, can clutter your inbox and compromise your privacy. Fortunately, iOS offers several built-in features to help manage these messages, and third-party applications like Robokiller provide additional protection.
How Can I Block Messages from Unknown Senders on iOS?
iOS provides a feature to filter messages from unknown senders, moving them to a separate tab in the Messages app. To enable this:
- Open the Settings app.
- Tap Messages.
- Toggle on Filter Unknown Senders.
This will create an Unknown Senders tab in your Messages app, where messages from numbers not in your contacts will be sorted. (support.apple.com)
How Do I Report Spam Messages on iOS?
Reporting spam messages helps improve spam detection. To report a message:
- Open the message from the unknown number.
- Tap Report Junk at the bottom of the message.
- Confirm by tapping Delete and Report Junk.
This action sends the sender's information to Apple and deletes the message from your device. (support.apple.com)
How Can I Block Specific Numbers on iOS?
To block messages from a specific number:
- Open the message from the number you want to block.
- Tap the contact at the top of the screen.
- Tap the info icon.
- Tap Block this Caller.
This will prevent the blocked number from sending you messages. (support.apple.com)
How Does Robokiller Help Block Unwanted SMS Messages?
Robokiller is a third-party app designed to block spam calls and texts. It uses a three-layer approach to filter texts:

To enable SMS Spam Protection with Robokiller:
- Open the Settings app.
- Tap Messages.
- Tap Unknown & Spam.
- Toggle on Robokiller.
Filtered messages will appear in your SMS Junk folder in the Messages app. (support.robokiller.com)

While iOS offers basic filtering and reporting features, Robokiller provides more advanced protection:
- Advanced Filtering: Robokiller's three-layer approach offers more comprehensive filtering compared to iOS's built-in features.
