Apple 6 blacked me out. Can he still see my phone and text messages?

You can't see it if it's painted black.

Listen carefully after dialing the other party's mobile phone. If you hear a half tone, you will be prompted to turn off or stop, so it is likely to be blacklisted by the other party.

Then users can try to use VoIP or other mobile phone numbers, and then try to dial. If they can dial normally, they can be sure that the previous number has been blacklisted.
