12306 why can't I get a text message after my mobile phone is verified?

Hello! If you don't receive SMS or verification code, it may exist in the following situations:

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

2. If you still can't get it after deleting it, I suggest you change the machine or card to see if it is caused by hardware;

3. Check whether it is intercepted by mobile phone interception software;

4. Check whether the cell phone signal is normal and try to test whether it can be received in other places.

After removing the above reasons, it still can't be used normally. You can click /qAHfS for feedback, and we will check and handle it as soon as possible.
