To modify the registered mobile number for a motor vehicle, the owner needs to bring their original ID card to the internet service window of the vehicle management office. The following are the impacts of not changing the registered mobile phone number: 1. Registration requirements online: Some vehicle owners may find that the phone number registered with their driver's license or vehicle registration is no longer in use but was not updated in time at the vehicle management office. Even if they wish to modify their information online, they cannot register successfully if the phone number used for registration does not match the previously registered one. 2. Potential inconveniences: Failing to update the registered phone number for the vehicle in a timely manner can lead to several issues. If the driver's mobile phone number changes and is not updated at the vehicle management office, they will not receive SMS reminders. This could result in overdue renewal or inspection of the driver's license, leading to point deductions, fines, or even license revocation in severe cases, causing significant inconvenience to daily life and travel.
