Why can't Apple send short messages?

If your mobile phone can't send short messages, you can try to restart it or change your mobile phone for testing, and check whether the following conditions exist:

1. The number of the short message center is set incorrectly, please re-enter the correct number of the short message center;

2. No signal or insufficient battery;

3. The system is busy during the peak period of holiday SMS sending, so it is suggested that you try again later or avoid the peak period of sending;

iv. the sending format is incorrect. If you send SMS to PHS users, you need to add the area code before the number;

5. The sending time of the short message exceeds 24 hours;

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

VII. Being blacklisted by SMS;

VIII. Insufficient number balance;

9. SMS inbox and outbox are full.

if the above reasons cannot be solved, you can contact the local manual customer service or go to the business hall to confirm whether the SMS function is enabled and hand it over to the staff.
