The short message could not be sent or was blocked.

The processing method that the mobile phone cannot send short messages is as follows:

1, you can change your mobile phone to see if you can send and receive short messages;

If you can send and receive short messages, I suggest you re-insert the card into your mobile phone and send yourself a short message to see if you can receive it.

3. If not, I suggest you check whether there is something wrong with the sim card;

4. Check whether the number of the SMS center is set correctly;

5. Bring the mobile phone card to the local business hall for testing or replacement.
