What if the Unicom number can't send a message?

If your Unicom mobile phone card can't send short messages, please check whether receiving short messages is normal and whether the following conditions exist:

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

Whether the status of your Unicom card is normal and whether it is stopped;

SMS Inbox and Outbox are full;

If the above reasons cannot be solved, you can contact the local 100 10 manual customer service or go to the business hall to confirm whether the SMS function is turned on and hand it over to the staff.
