What's wrong with Apple's 6P WeChat message?

Apple's mobile phone WeChat can't send messages for the following reasons:

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.

5. The WeChat version is low. You can upgrade WeChat to the latest version and re-operate.

Apple can't send messages via SMS for the following reasons:

1, Apple's SMS can't be sent out, maybe there is something wrong with the SMS center.

2. The other party has set up a firewall, and your message was successfully sent, but other people's mobile phones refused to receive it. Charge as usual, indicating that the delivery was successful, but the receipt received was a failure.

3. The other party's mobile phone is turned off, or there is no signal. The short message you sent was not received by the other party, but if the time exceeds the validity period of the short message set by the other party, you will also be prompted to send it successfully, but the receipt you received is a failure.

4. Communication problem, that is to say, it has nothing to do with the mobile phones of both parties. It may be caused by poor signal or communication error.
