I can't get a short message when I set the password for the railway e-cartoon.

The railway e-cartoon has set the transaction password, but you can't receive the message. Check whether your personal information and telephone number are wrong. When the phone number is filled in incorrectly, the SMS verification code will be sent to another phone number, which makes me unable to receive information. At the same time, when the personal information is filled in incorrectly, the railway e-cartoon will recognize the wrong information and then will not send a message. In order to make it more convenient for passengers along the Changsha-Zhuzhou-Xiangtan intercity railway to enter the station, China Railway Guangzhou Bureau Group Co., Ltd., Hunan Intercity Railway Company, China Railway Yintong Payment Company and China Bank developed the "Railway E-Card" project. After the "railway e-cartoon" was put into use, the "inspection integration" of passengers getting on and off the bus was realized, and the process of entering and leaving the station was simplified. You don't need to buy tickets in advance to use "Railway E Cartoon".
