Unicom's phone bill is lower than 10 yuan. Can I send short messages?

Yes, if the mobile phone can't send short messages, the processing method 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.

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

5. Call the hotline 100 10 to verify whether the SMS function is normal, or bring your mobile phone card to your business hall for testing or replacement.
