Unicom micro usim card SMS can't be sent out.

The mobile phone can't send short messages, so you can try to restart the mobile phone or change it to test whether there are any of the following conditions:

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

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 short message sending time exceeds 24 hours;

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

6. Blacklisted by SMS;

7. Insufficient quantity balance;

8. SMS inbox and outbox are full.

If the above reasons cannot be solved, you can contact the local manual customer service or go to the business hall to confirm whether the SMS function is enabled and hand it over to the staff.
