The "Jiaoxintong" system is a public convenience system specifically designed for drivers. It's easy to use; by simply sending a text message via China Unicom mobile phone, users can query at any time and anywhere whether the motor vehicle they are driving has committed any traffic violations. Additionally, it allows users to check vehicle annual inspection notifications, driver’s license reviews, road information, and traffic police announcements.
The specific on-demand query methods of "Jiaoxintong" are as follows:
1. Send "P + valid license plate number" to access the "Violation Inquiry" information;
2. Send "G" to access "Laws and Regulations" information;
3. Send "D" to access "Road Conditions" information and Tianjin gasoline prices;
4. Send "J" to access "Urgent Notifications" information.
The fee for each of the above services is 1.00 yuan per message. Users can subscribe to the monthly package service by sending "JT" to 10628900, with a fee of 5.00 yuan per month, and three messages will be sent every week.
