Railway 12306 didn't send a text message.

Check whether your mobile phone is turned on in airplane mode. After the airplane mode is turned on, the mobile phone will not receive any information. This will lead to your successful purchase and payment of train tickets online 12306, and your mobile phone will not receive information. Check whether the mobile phone number you are using has expired.

If you can find the information of your train number on the platform, and it has been successful, then there is no problem. I didn't receive the SMS notification. I suggest you check whether your SMS notification number is entered incorrectly, but sent to other mobile phones. Hope to adopt.

Now I don't send text messages separately when I buy train tickets. Instead, when you pay with Alipay or WeChat, there will be a check option to prompt you whether to use WeChat or Alipay to receive the ticket purchase information notice. If you need to receive it, just check and confirm it.

After the ticket purchase is successful, it is usually necessary to send the ticket purchase information. I didn't send you a message. You can confirm whether the ticket purchase is successful first. If successful, it may be that the system was busy at that time and there was no SMS reminder of ticket purchase information.
