There is no SMS to inform who to look for when booking tickets by mobile phone.

1, WeChat paid successfully, but did not receive a reminder message, which may be the reason for the network delay. Please check again in a few minutes. It may be because WeChat Pay has turned on "Do Not Disturb Messages", so just turn off this option. Let me demonstrate the specific operation method below, hoping to help you.

2. Receive relevant notification information such as ticket purchase, ticket exchange and refund through WeChat. Check whether you have received the short message or email sent by 12306.cn that successfully purchased tickets online. After the online payment is successful, you can check the order through official website Mobile APP or Railway12306.cn.

3. Under normal circumstances, after the order number is generated, the customer's mobile phone or email address should receive a prompt message of successful reservation. If there is no prompt information, the booking is unsuccessful. If successful, the website 12306 didn't send the SMS to the mobile phone. Maybe the website system was busy and didn't send the SMS to the mobile phone.

There may be a slight time difference. If you wait patiently, you will succeed. He will send you a short message after buying a ticket successfully in the future, and your ticket information will be displayed in the short message.
