What does it mean that Apple has an exclamation point when texting?

An exclamation point when a mobile phone sends a text message indicates that the message failed to be sent. It is suggested to click the exclamation point and send it again. Generally, the reasons for sending failure are poor cell phone signal, cell phone arrears, and possibly insufficient memory space. Details are as follows:

1. A red exclamation mark appears on Apple's SMS, indicating that your SMS was not sent successfully. You can click the exclamation point and send it again.

2. The same is true for Android phones. A red exclamation mark appears on the short message, indicating that the short message failed to be sent.
