SMS is locked, so you can't send messages, but you can receive messages. I called customer service 100 10 for several days, but no one answered.

If the mobile phone can't send short messages, you can try to restart or replace the mobile phone for testing to check whether the following conditions exist:

1. SMS center number is set incorrectly;

2. No signal or low battery;

3. Because the system is busy during the holiday short message sending peak period, it is suggested to try again later or avoid the sending peak period;

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

5. The short message sending time exceeds 24 hours;

6. The mobile phone shields the short message sending function;

7. Blacklisted by SMS;

8. Insufficient quantity balance;

9. SMS inbox and sending box are full;

10. Query whether the SMS function is turned on;

If the above reasons cannot be solved, you can contact Unicom's manual customer service for processing.

100 10 customer service is Unicom's unified service hotline. When sudden traffic such as failure and charge deduction leads to manual busy, the connection rate will drop. It is suggested that you can also inquire or handle business through online business hall, mobile phone business hall, SMS, WeChat and other self-service channels.
