Nobody likes spam or junk messages cluttering their inbox, and Apple has made it easy to report and block such messages. Whether you’re using iMessage or regular SMS/MMS, here’s how to report spam messages and keep your messaging experience clean and hassle-free:

For iMessage Users:

  1. Identify the Spam Message: In your list of messages, locate the spam message that you want to report.
  2. Report Spam Message: Tap and hold the spam message. A menu will appear; from this menu, tap “Report Junk.”
  3. Confirm Report: Alternatively, if you’ve already opened the spam message, scroll to the bottom of the message and tap “Report Junk.”
  4. Delete and Report: After tapping “Report Junk,” you’ll be given the option to “Delete and Report Junk.” Confirm this action.
  5. Message Sent to Apple: Once you’ve reported the spam, the sender’s information and the message content are sent to Apple for review.
  6. Message Removal: The reported spam message is permanently deleted from your device.

For SMS/MMS Users:

  1. Identify the Spam Message: In your Messages app, locate the spam message that you want to report. This could be a regular SMS or MMS message.
  2. Forward to SPAM (7726): Create a new message and forward the spam message to the shortcode “7726.” This shortcode spells “SPAM” on most phone keypads.
  3. Receive Confirmation: You’ll receive a response from your carrier confirming the receipt of the report. This helps your carrier take action against the spam sender.

Note: Reporting spam messages may vary depending on your carrier and your location. Some carriers might have specific instructions or shortcodes to report spam. Check with your carrier for precise details.
