Can I still hear from the other party after hacking my phone with my Apple phone?

No, the function of Apple's blacklist: after hacking someone's phone number, you can refuse someone's phone calls and text messages.

When it is set to call rejection or blacklist, if the other party sends a short message, the mobile phone can still receive this short message. SMS is stored in your mobile phone blacklist or call rejection record, which contains not only the call rejection record, but also the SMS interception record.
