The Unicom card used by LeTV 1s can receive short messages, but cannot send them out. What's wrong with Unicom cards being different? I'm Hebei Netcom, a new mobile phone.

If the consultation is that the mobile phone can't send short messages, it is suggested that the following methods can be used for investigation:

1. Suggest changing your mobile phone to see if you can send text messages.

2. If you can send a short message, 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, it is recommended to check whether it is a sim card problem;

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

If the problem still cannot be solved, it is suggested that you can take your mobile phone card to the local business hall for testing.
