If the other party is set to refuse to receive my phone calls and text messages, is there any hint here?

Dear, if the other party blacklists your phone, it can achieve the purpose of rejecting your phone calls and text messages. At the same time, it can set a ring back tone for you to call his phone, which can be turned off, but it is not in the service area, or it can't be connected, but your mobile phone has no prompt.
