Unicom 4g paid the phone bill and didn't receive the call reminder. What is the solution?

If you can't receive the phone bill reminder message, I suggest you check it in the following places:

1, you can check whether the mailbox is full first. If it is full, please delete some information.

2. I still can't get it out after deleting it. I suggest you change the machine or card to see if it is a hardware factor.

3. After eliminating the above reasons, it is suggested to try to test whether it can be received in other places to see if it is the reason for the weak local signal;

4. It is not excluded that you intercepted the short message by using the third-party software.

If the above problems do not exist, it may be related to network function or delayed arrival. Please contact the local manual customer service to handle this problem.
