There's nothing wrong with it. Only send it, not send it. It was cancelled in the process of sending. Whether it can be sent out has something to do with the difference between mobile phones. Some mobile phones can't be sent out if they are cancelled halfway, but Nokia phones can't be sent out if they are cancelled halfway, and they can still be sent out. You can look at your mobile phone. There are usually SMS reports. If the other party receives your message, your mobile phone will receive a message report. If the other party does not receive it, there is no information to report.
