Why does 12306 keep texting me? I didn't subscribe. Is there any way to cancel or unsubscribe?

It may be that the current mobile phone number has been bound to the account number of 12306, and China Mobile or China Unicom will have the habit of re-listing the old number after cancellation, which can be handled in the following two ways:

1. If you have an account of 12306, you can do real-name authentication of your mobile phone number and bind it to your account of 12306.

2. With 12306, you can call 12306, and the manual customer service will unbind this mobile phone number from 12306.

The specific steps of the first treatment method are as follows:

1. First log in to the webpage of 12306 and click "Account Security" in the menu list on the left.

2. On the right side of the account security page, find the "mobile phone binding" option, and then click "Modify" at the back.

3. Click Modify to pop up the binding mobile phone modification page, enter the mobile phone number and password, and click OK.

4. After the verification is successful, the system will prompt that the password has been modified successfully, and the mobile phone number will be bound to its own 12306, so there will be no wrong subscription prompt.
