What's the matter that Unicom's mobile phone number can't send short messages?

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. SMS center number is not set correctly. Please re-enter the correct SMS center number.

2. There is no signal or the battery of the mobile phone is insufficient;

3. The balance of mobile phone number is insufficient.

4. The system is busy during the peak period of holiday SMS sending, so it is suggested to try again later or avoid the peak period.

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 the staff will assist in handling it.
