How can I know that the other party's mobile phone refuses to send a message?

1, the other party hacked you, depending on the specific situation, whether to hack the phone or the SMS.

2. Under normal circumstances, after the incoming call is blacked out, the phone can't get through, but the short message can still be received.

3. After hacking the short message, the other party can still receive the sent short message, but it has been intercepted by the mobile phone. If the other party wants to view the intercepted SMS, they need to view the SMS content in the intercepted SMS.

4. There is another special situation, that is, the other party deletes you from the blacklist. At this time, when you send a message to the other party, a red warning symbol will also appear on the left side of the message, and the bottom will display "XXX has started friend verification, and you are not his (her) friend.

Please send a friend verification request first, and you can chat only after the other party has passed the verification. "hint. The difference is that when you send a verification request, the above prompt will continue to appear, because the other party can no longer receive the information you sent.
