What is the reason why you didn't receive SMS and email when booking tickets on 12306 website?

1. Login account 12306, and click "Unfinished Order" or "Completed Order" to query the order status. If the payment is successful (the reservation is successful), don't worry even if you don't receive the SMS. After all, telecom operators may have information loss and information delay in the process of processing information.

2. Failure to receive SMS will not affect your ticket collection. You can find the corresponding order in the completed order and record the order number. When picking up tickets, if you pick up tickets at the train station window, you only need to provide your ID card and order number. If you pick it up at the ticket vending machine, you only need to use your ID card.

3. Passengers should remember to pick up the tickets in advance after booking at 12306, which is risky (it may miss the train).
