Just bought Meizu MX2 Unicom contract machine has been unable to send messages.

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

1. I suggest you change your mobile phone and see if you can send and receive short messages.

2. If you can send and receive short messages, I suggest you plug the card back 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 it is a sim card problem.

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

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