Receiving suspicious messages on your iPhone can be both annoying and potentially harmful. Fortunately, iOS offers several features to help you manage and block these unwanted communications.

iOS provides a feature to filter messages from unknown senders, keeping them separate from your main inbox. To enable this:

3. If you haven't opened the message, swipe left on it, tap Delete, then tap Delete and Report Junk.
4. If you've opened the message, tap the Report Junk link at the bottom, then tap Delete and Report Junk.

This action sends the message to Apple and, depending on your carrier, may share it with them as well. (support.apple.com)
