How to solve the problem that Unicom can't send short messages?

If you have any arrears, you can restart your mobile phone after paying it off. If the status of the number is abnormal, such as stopping the insurance number, reporting the loss and stopping the loss, etc. , you can contact customer service and restart your phone to try.

Mode 2: SMS function is abnormal. In this case, the user can call the manual station of 100 10 or contact other manual customer service channels to confirm whether the number message status is normal and handle it.

Mode 3 can't send short messages to other carrier numbers. In this case, you can call 100 10 or contact other manual customer service channels to inform the specific situation and give feedback, and Unicom will verify the reply.

Mode 4 cannot send a single number, which may be caused by the other party. Suggest contacting each other.

Mode 5: The number of SMS center is set incorrectly or not. Please check whether the SMS center number is set. If set, check whether the number is correct. Reminder: iPhone needs to call to delete SMS center number first, and then call to add it.
