How to solve the problem that Unicom can't receive SMS?

First, check whether the status of the mobile phone card is normal and whether there is any arrears. If not, it is recommended to test whether all SMS numbers are not received, or whether individual applications or bank verification codes are not received. Restart the phone and put the mobile phone card into other normal phones to detect it.

In addition, it can be restored by resetting the number of the SMS center. If all the above methods have been tried, there is still no recovery. It is suggested to contact the operator in time for feedback processing.
