How do I turn message blocking off on Iphone 7 please help

Block phone numbers and contacts on your iPhone, iPad, or iPod touch

With iOS, you can block contacts and phone numbers on your device. You can also filter iMessages from unknown senders and report iMessages that look like spam or junk.

Block a phone number or contact

There are a few ways that you can block a phone number or contact.

Phone

• If you're in the Phone app under Recents, tap  next to the phone number or contact that you want to block. Scroll to the bottom of your screen, then tap Block this Caller.

FaceTime

• If you're in the FaceTime app, tap  next to the phone number or contact that you want to block. Scroll to the bottom of your screen, then tap Block this Caller.

Messages

• If you're in Messages, open the conversation, tap the contact at the top of the conversation, then tap . Tap the name or phone number, scroll to the bottom of the Info screen, then tap Block this Caller.

When you block a phone number or contact, they can still leave a voicemail, but you won't get a notification. Messages that are sent or received won't be delivered. Also, the contact won't get a notification that the call or message was blocked.

You can use some third-party apps to detect and block spam phone calls.
