Excuse me, how to activate the secretarial service for Shandong Unicom car owners? What are the rates?

Shandong Unicom's 2G and 3G mobile phone users can edit the text message "9" or "9license plate number #last 4 digits of engine number" to 106558666 to customize the car owner's secretary service, in the format: 9LuA12345#6789. After customization, the user receives a message prompting the user that the customization has been successful. The license plate number and the last 4 digits of the engine number are successfully matched. At the same time, a text message is received corresponding to whether the vehicle has any violation information. The information fee is 3 yuan/month. Sending a text message to 106558666 to activate requires an additional communication fee of 0.1 yuan.
