Why can't I send messages to others on WeChat? It's not realistic to hack something, it's just a red exclamation point, and everyone else is fine! this

You are on the other party's blacklist-automatically rejected your message-the message you sent may be automatically rejected without receiving it-and you want the other party to pull you out of the other party's blacklist.

There may be other reasons why WeChat can't send a message to someone:

1. The mobile phone network is unstable. We can check the mobile phone network by opening the webpage.

2. There is too much information in WeChat memory. You can click "Settings", select the "General" menu, and then click "Clean up WeChat storage space".

3. There are too many chat records on WeChat, so you can clear some chat records.

4. If you are blacked out by the other party, you can send a message to others to see if it is successful, so as to know whether it is blacked out by the other party.
