Why can't the mobile phone receive the verification code in 12306?

The mobile phone can't receive SMS verification code, which may be caused by the following reasons:

1. More than the collection times.

Solution: You can only get the verification code three times a day. If you exceed the number of times today, please try again tomorrow.

2. Mobile phone security software interception (for smartphone users who have installed security software)

Solution: Open the mobile phone security software, temporarily turn off the interception function, and then try to get the verification code again.

3. The SMS gateway is congested or abnormal.

Solution: When the SMS gateway is congested or abnormal, the sent SMS will be delayed or lost. I suggest you try again later.

4. Mobile phones are used abroad or overseas mobile phones are used.

Solution: Due to the influence of mobile phone service provider's business, the mobile phone cannot receive the verification code when it is used abroad or used abroad. It is recommended to replace the mobile phone as much as possible.

People around you can use it normally, but they can't get it themselves.

Solution: It may be the phone itself. It is recommended to change the mobile phone card to someone else's mobile phone and try again.
