Hello, what is the reason for turning off my SMS function?

1. If your mobile phone can't send short messages, you can try to restart or change your mobile phone for testing to see if the following conditions exist:

1 SMS center number is set incorrectly, please re-enter the correct SMS center number;

2 No signal or insufficient battery power;

3. Because the system is busy during the holiday short message sending peak period, it is suggested that you 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 SMS sending time exceeds 24 hours;

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

7. The mobile phone number is blacklisted for sending short messages such as illegal acts or sending short messages in groups exceeding the upper limit;

The balance of number 8 is insufficient;

9 SMS Inbox and Outbox are full.

2. According to the information you provided, if you receive a phone call from our staff to remind you to reopen the SMS function, our company will handle it according to the process. Please wait patiently or contact Unicom's manual customer service for verification. The specific situation is subject to local policies.
