Unicom can't send SMS.

Hello, if your mobile phone can't send SMS, you can see if there are any reasons as follows:

1. SMS service is not enabled on your mobile phone, you can contact 11 customer service or go to the local business hall to enable this function;

2. The number of the short message center that is not set or set is wrong, just reset it;

3. The signal is weak, there is no signal or the battery of the mobile phone is insufficient, which causes the information not to be sent normally;

4. Due to the busy system, especially during the peak period of sending short messages on holidays, it is suggested that you try again later or avoid the peak period;

5. The sending format is incorrect. If you send SMS to PHS users, you need to add the area code before the number;

6. SMS sending and retention is valid for 24 hours;

7. Whether the SMS inbox and outbox are full;

8. I suggest you restart your phone or change your mobile phone to test it.

except for the above simple troubleshooting, it still can't be solved. You can contact manual customer service for handling.
