Why can't the mobile phone of 156 receive the verification code?

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

1. You can check whether the mailbox is full first, and if so, please delete some information;

2. You still can't receive 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 it can be received in other places to see if it is the reason for the weak local signal.

if none of the above problems exist, please contact the local manual customer service to handle this problem.
