Why can't Unicom business hall get SMS verification traffic?

Unicom business hall can't get the SMS verification process. You can try the following methods:

1, you can change the machine or card to see if it is due to hardware factors.

2. Check whether the mailbox is full first, so the information can't be received. If yes, please delete some information.

You can try to test whether you can receive it in other places and see if it is because of the weak local signal.

4. The mobile phone settings put the SMS in the trash can, so you can check it in the SMS trash can first.

5. It may also be because there are many users and the system is slow to send text messages. Suggest trying again later.

6. If the above reasons can't solve the problem, please contact Unicom's manual customer service for processing.
