Why can't Unicom send the message of 106?

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;

2. If you can send and receive short messages, it is recommended to re-insert the card 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 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.

If the above methods can't eliminate the fault, it is recommended to call the local Unicom customer service hotline for consultation.
