My mobile phone number has changed. How to change the previously bound short message that violates the car regulations?

If you still have that number, take the previous number, unbind the previous one, and then bind it with a new mobile phone. If your previous mobile phone number is missing, you can go to the website of the vehicle management office and submit your new information. If it is too troublesome, you can directly call the convenience service phone of the traffic control office for consultation!

Only on behalf of personal views, don't spray if you don't like it, thank you.
