I am Unicom in Jinzhong, Shanxi. How can I send a text message?

Mobile phones can't send short messages for the following reasons:

1. The mobile phone is in an abnormal state, such as arrears, and it is impossible to send short messages. Just pay the arrears at this time.

2. SMS service is not enabled on the mobile phone. You can call 100 10 to contact customer service or activate this function in the local business hall.

3. No or wrong SMS center number is set, just reset it.

4. The signal is weak, there is no signal or the battery of the mobile phone is insufficient, which leads to the information not being sent normally.

5. Because the system is busy, especially during the peak period of texting on holidays, I suggest you try again in the future or avoid the peak period.

6. The sending format is incorrect. If you send a short message to PHS users, you need to add the area code before the number.

7. If a large number of short messages are sent in a short period of time, which causes the mobile phone to enter the short message blacklist, it is suggested that you contact the local 100 10 to inquire about the specific situation and help you solve it.
