Real-name authentication for the built-in SIM card in the vehicle can be done through online self-service authentication or by visiting a Tesla service center. Below are the relevant details regarding the real-name authentication for the built-in SIM card: 1. Online self-service authentication: Search for the WeChat public account "Unicom Smart Network Real-name Registration," follow it, click on "Real-name Authentication," and submit the required information. 2. Tesla service center: Bring the necessary documents to the nearest Tesla service center. Required documents include: For individual registration: original vehicle registration certificate, original ID card of the vehicle owner or agent, and a photo holding the ID; For corporate registration: "Corporate Real-name Authentication Authorization Letter," original vehicle registration certificates for all vehicles, original ID card of the agent, and a photo holding the ID.

Just helped a friend with this recently! The real-name authentication for the built-in SIM card in a vehicle is quite similar to mobile SIM card authentication. You'll need to prepare your original ID card and vehicle license, then open the network settings menu in the car's infotainment system to find the real-name authentication entry. Follow the prompts to take photos and upload the front and back of your documents, and also complete a facial recognition verification. Some automakers may require a photo of the VIN—remember to check under the passenger seat for that stamped serial number. Once approved by the carrier, a success notification will pop up on the car's screen, and the 4G network will be ready for streaming music or using navigation. The whole process takes about ten minutes, but if the system lags, it's best to try again the next day.

Failure to replace the air filter for an extended period can lead to excessive dust accumulation in the filter, resulting in insufficient air intake. This causes low idle speed and consequently engine vibration. Replace the filter element. A disconnected circuit directly affects ignition, leading to engine vibration. Use a multimeter to measure resistance and replace the wire with significantly higher resistance (several times higher). If your vehicle has reached such usage duration or mileage, simply replace it directly.
