Why am I not allowed to send text messages when I am Tencent Wangka?

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.
