Apple's mobile phone is plugged in, and the SMS displays an exclamation point. Can you still get the text message?

A red exclamation mark will appear on the sent email, indicating that the email was not sent. If the mobile phone can't send short messages, you can try to restart or replace the mobile phone for testing to check whether the following conditions exist:

1. SMS center number is not set correctly. Please re-enter the correct SMS center number.

2. No signal or low battery. It is recommended to recharge and try again.

3. The system is busy due to the peak of sending short messages on holidays, so it is suggested to try again later or avoid sending during peak hours.

4. The sending format is incorrect. If you send a short message to PHS users, you need to add the area code before the number.

5. The short message sending time exceeds 24 hours;

6. The mobile phone shields the short message sending function;
