Why can't you send text messages?

If the mobile phone can't send SMS, you can try to restart the mobile phone or change the card to check whether the following conditions exist:

1. Whether the SMS center number is set correctly, please enter the correct SMS center number;

Second, there is no signal or the mobile phone battery is insufficient;

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;

Fourth, 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;

Sixth, the mobile phone shields the short message sending function;

Seven, the other party's number is included in the SMS blacklist;

8. Insufficient quantity balance;

Nine, SMS inbox and outbox are full.

In order to eliminate the above problems, it is recommended that you contact the manual customer service hotline for feedback.
