What if I can't send a text message to iOS 12?

If the mobile phone can't send short messages, you can check the following questions:

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

2. There is no signal or the battery of the mobile phone is insufficient;

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

4. The sending format is incorrect;

5. The short message sending time exceeds 24 hours;

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

7. Blacklisted by SMS;

8. Insufficient quantity balance;

9.SMS inbox and outbox are full.

If the above reasons cannot be solved, you can contact the customer service hotline of your local mobile phone card for feedback.
