How to Block Unknown Sender Texts on iOS

Receiving unsolicited text messages from unknown senders can be both annoying and potentially harmful. Fortunately, iOS offers several built-in features to help you manage and block these messages effectively. In this guide, we'll explore how to utilize these features and introduce Robokiller, a market-leading solution for enhanced protection against unwanted texts.

How Can I Filter Messages from Unknown Senders on iOS?

iOS provides a built-in feature called "Filter Unknown Senders" that separates messages from contacts not in your address book into a separate tab. To enable this feature:

  1. Open the Settings app on your iPhone.
  2. Scroll down and tap on Messages.
  3. Toggle on Filter Unknown Senders.

Once activated, your Messages app will display a new tab labeled "Unknown Senders," where messages from unfamiliar contacts will be directed. This helps keep your main inbox focused on messages from known contacts. (support.apple.com)

How Do I Block Text Messages from Specific Numbers on iOS?

If you receive unwanted messages from a specific number, you can block that contact directly:

  1. Open the Messages app.
  2. Select the conversation with the sender you wish to block.
  3. Tap the contact's name or number at the top of the screen.
  4. Tap the info icon.
  5. Scroll down and tap Block this Caller.

Blocking a contact will prevent them from sending you text messages, calls, and FaceTime requests. (support.apple.com)

How Can I Report Spam Messages on iOS?

To report spam messages received via iMessage:

  1. Open the Messages app.
  2. Select the conversation containing the spam message.
  3. Tap the info icon at the top of the screen.
  4. Tap Report Junk.
  5. Confirm by tapping Delete and Report Junk.

This action sends the message to Apple and deletes it from your device. Note that you cannot report a message after replying to it. (support.apple.com)

How Can I Silence Notifications from Unknown Senders on iOS?

To prevent notifications from unknown senders while still receiving their messages:

  1. Open the Settings app.
  2. Tap on Notifications.
  3. Select Messages.
  4. Tap Customize Notifications.
  5. Toggle off Unknown Senders.

This will stop notifications for messages from unknown senders, but their messages will still appear in the "Unknown Senders" tab in the Messages app. (howtogeek.com)
