You can reduce the number of unwanted text messages you receive when you block individuals, filter unknown senders, and report spam or junk messages.
Note: A known sender is anyone you’ve added to the Contacts app or sent a message to.
When you block a specific contact or phone number, messages from that person or number aren’t delivered. (The person sending the message doesn’t know that their message was blocked.)
Go to the Messages app stop its notifications.
If you’re still having trouble with unwanted messages, see the Apple Support article in the top-left corner of the screen, then tap Unknown Senders.
Note: You canʼt open any links sent by an unknown sender until you make them a known sender—by adding them to your contacts or replying to the message.
When you use Wireless carrier support and features for iPhone.
If you received the message with iMessage, it’s sent to Apple with the sender’s information, and the message is permanently deleted from your iPad.
If you accidentally report and delete messages, you can > Apps > Messages.
Tap Blocked Contacts, then do any of the following:
Unblock a number you’ve blocked: Swipe left on a number in the list, then tap Unblock. Or tap Edit, then tap Recognize and avoid phishing messages, phony support calls, and other scams.
