BMW ConnectedDrive utilizes a built-in SIM card pre-installed in the vehicle, with data packages purchased in advance by BMW. The vehicle's onboard 4G network operates on the same principle as a mobile phone SIM card network. Based on cutting-edge cloud technology platform, BMW ConnectedDrive offers extensive scalability with four major functional categories: journey management, vehicle services, premium mobility services, and lifestyle & entertainment services. Additional details about ConnectedDrive are as follows: 1. Introduction: Internet of Vehicles (IOV) refers to a dynamic mobile communication system enabling interaction between vehicles, roads, people, and sensing devices, achieving vehicle-to-public network communication. 2. Functionality: It integrates intelligent traffic management, smart dynamic information services, and vehicle control - representing a typical application of IoT technology in transportation systems. This system serves as an essential pathway for mobile internet and IoT to achieve substantive business development, combining future-oriented information communication, environmental protection, energy efficiency, and safety technologies. Through vehicle-to-vehicle, vehicle-to-person, and vehicle-to-infrastructure connectivity, it enables information sharing by collecting vehicle, road, and environmental data. The platform processes, computes, shares, and securely publishes multi-source information, providing effective vehicle guidance and supervision according to various functional requirements, along with professional multimedia and mobile internet application services.

BMW's connected car data is typically provided by a built-in module, similar to our mobile phone's data service. They have a SIM card installed that connects directly to the mobile network, usually supported by BMW's partnered telecommunications companies, such as China Mobile or China Telecom carriers. That's how the data flows in. In practical operation, the system comes pre-configured with data connectivity when you buy a new car. You can access maps, music, and other features through the vehicle's infotainment system. I've driven a friend's BMW with this feature and found it quite convenient—no need to constantly tether to a mobile hotspot. Additionally, BMW usually provides some initial free data trial period before you need to subscribe for continued service. Just remember to use it wisely—don't download too much content at once and exhaust your data, as this could affect real-time navigation updates.

The data source for BMW's ConnectedDrive is quite straightforward. As a regular BMW owner, I've experienced it firsthand—the data comes from the car's own built-in system, essentially like having a built-in data SIM card, so you can access online services as soon as you get in the car. Typically, BMW partners with mobile carriers to ensure stable connectivity while driving, automatically switching to backup channels in weak-signal areas like rural regions. In practice, I manage data usage via the central control screen, checking remaining data to avoid overages. Regarding privacy, I trust BMW encrypts user data transmissions to protect driving locations or preferences from misuse. Overall, this service makes in-car connectivity hassle-free without relying on phone hotspots.

The data source on BMW vehicles is straightforward: it primarily relies on the built-in SIM card to transmit data via the mobile network, supported by BMW's contracted carrier, with users required to renew their data plans later. From a cost perspective, I've noticed that new cars often come with free data packages for the first few months, after which charges apply. There's a significant price difference between various plans, so using data sparingly can save money. It's advisable to regularly check settings to avoid unnecessary usage. Related services include remote vehicle control features, which also consume data—don't forget to manage these expenses.
