Oppo mobile phones cannot send international short messages. What happened?

1. You can change your mobile phone to see if you can send and receive short messages.

2. 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, check whether there is a problem 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.
