What if the card of 8p Unicom can't send a short message with the American version of the card sticker machine?

Unicom users can't send short messages on their mobile phones. You can try to restart or change their mobile phones to test whether there are any of the following situations:

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 that you try again later or avoid the sending peak period;

4. The sending format is incorrect;

5. The short message sending time exceeds 24 hours;

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

7. Insufficient quantity balance;

8. SMS inbox and outbox are full.

If the above reasons cannot be solved, you can contact the local Unicom artificial customer service 100 10 for handling.
