Why didn't you receive the number verification code of 130?

Unicom users can't receive SMS or verification code for the following reasons:

1, you can check whether the mailbox is full first, and if it is, please delete some information;

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

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

If none of the above problems exist, please contact customer service to deal with this problem.
