Isn't it good to send my expression online circle?

There may be something wrong with your network here. Because it can't be sent. Or the other party's network can't work. Although you sent it, your side has always shown that it was not received by him. You can try sending a message first. If it shows that the other party has received it, there is something wrong with your network.

It may be because the user settings did not turn on iMessage, which led to the failure of sending short messages imitating my expression. Just go to Settings-Information and open iMessage information. 1. Click Info, open phone settings, and then click Info. 2. Select on. Enter the information setting interface and open Apple imessage information.
