Bluetooth SIM Access (Trial) is an Android application designed to implement the Bluetooth SIM Access Profile, enabling users to connect their HTC, Samsung, or Sony phones to compatible car kits from brands like Volkswagen, Skoda, Audi, and Porsche. This application requires root access for functionality and operates in a trial mode, allowing a connection for a duration of 10 minutes before disconnecting. To employ the app effectively, users must follow additional installation steps and check compatibility with their specific device model.

Upon initiating the application, it runs a background service that facilitates the connection to the car kit. Users can easily start the service and enjoy the convenience of remote SIM access directly from their vehicles. This app is particularly useful for those who frequently use their mobile phones for communication while driving, enhancing safety and connectivity on the road.
