Self-service unsealing restrictions but no verification code?

You can't receive SMS or verification code due to the following reasons:

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

2. If it is still not received after deletion, you can change the machine or card to see if it is a hardware factor;

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

4. Contact the sender to see if the sender has successfully sent or failed.

Excluding the above reasons, it is recommended to contact Unicom customer service for feedback.
