What's the matter with the message that it hasn't been sent yet?

If the mobile phone can't send SMS, you can check it in the following ways:

1, whether the number is in normal state;

2. Check whether the SMS function is enabled;

3. Check the current signal network;

4. Check whether the SMS center number set in the mobile phone terminal is correct;

5. Check whether the mobile phone card/mobile phone terminal is faulty.

In addition, if you call Unicom customer service and have registered for you, please keep the number open and a staff member will contact you.
