Can the mobile phone number of SMS notification of vehicle violation be changed to not the owner's?

You can't. Traffic violation is a violation of traffic management. This behavior is not allowed to change the mobile phone number notified by SMS to the mobile phone number of the non-owner. Because you can't receive valid information if you change it, illegal information has been hung in the owner's name and must be handled by the traffic police brigade, so you can't change it. Travel as far as possible to avoid traffic violations, safety first.
