12306 I used my account to buy tickets, and my mobile phone also received text messages. Why did my mother get the message?

12306 is a nationwide networked train ticket selling system. To buy a train ticket on 12306, you need to provide personal information and mobile phone number in order to receive the information of ticket purchase, ticket collection and ride. Therefore, when you use your account to buy a train ticket on 12306, your mobile phone will receive a short message about the ticket purchase information.

If your mother's mobile phone receives the same message, there may be the following situations:

1. When you bought a train ticket, you mistyped your mother's mobile phone number, resulting in the ticket purchase information being sent to her mobile phone.

2. Your mobile phone number and your mother's mobile phone number are bound under the same account number 12306, so when you buy a train ticket, the system will automatically send the ticket purchase information to your mother's mobile phone.

3. You use your mother's account 12306 to purchase tickets, so when you buy a train ticket, the system will automatically send the ticket purchase information to the mobile phone number bound to this account, that is, your mother's mobile phone.

If you confirm that you didn't enter your mobile phone number by mistake or use your mother's account to buy tickets, it may be because your mobile phone number and your mother's mobile phone number are mistaken for the same person, or there are other system errors.
