I bought a train ticket for my friend. I logged in with my account on official website. The ticket information is written on a friend's ID card and mobile phone. Why did you send a text message to my mobile phone? This is normal, because the ticket was purchased with your account, and you left your mobile phone number when you registered your account, so the text message will be sent to your mobile phone;

However, it should be noted that the name and ID number in the SMS must be the same and belong to the same person. In other words, no matter whether the ticket information you fill in is correct or not, you will not be able to get the ticket normally.

If you are not sure, you can log in to 12306 to check your reservation order, which will contain detailed information.
