Is it mandatory to use the built-in SIM card in Audi cars?

Audi cars do not necessarily require the use of the built-in SIM card; you can also use your own SIM card. Additional information: Relevant introduction about Audi is as follows: 1. Brand Introduction: Audi is an automobile brand under the Volkswagen Group in Germany, with its logo featuring four interlocking rings. Its headquarters is located in Ingolstadt, Germany. 2. Main models include: Audi A1, Audi A3, Audi A4, Audi A5, Audi A6, Audi A7, Audi A8, Audi Q1, Audi Q2, Audi Q3, Audi Q5, Audi Q7, Audi Q8, Audi TT, Audi R8, as well as the S and RS performance series.

Over the years of driving my Audi, I've found that the manufacturer-provided SIM card isn't absolutely necessary, but it genuinely unlocks quite a few practical features. This card primarily handles the car's internet connectivity, enabling services like real-time traffic updates, online map upgrades, and emergency calls. However, I often use my phone's hotspot to connect the car's system without any issues. The main differences are: the built-in SIM allows direct internet access for faster service activation, while using a phone hotspot requires manual connection each time and means leaving your phone in the car when parked. If you just need basic navigation and music, a phone hotspot suffices, but for experiencing Audi's full suite of connected services, that little card plays a crucial role.

As someone who frequently tinkers with in-car systems, my advice is practical: Audi's built-in SIM card is not mandatory. The key is whether you're willing to spend extra on its internet service plan. I've seen many owners simply use their mobile hotspot instead—it's very straightforward, just connect to Wi-Fi via the central control screen. The advantage of the built-in SIM is that the network automatically connects when the vehicle starts, making functions like remotely checking vehicle status or sending navigation routes smoother. But honestly, if you're just streaming music online, a hotspot is perfectly sufficient and can save you the annual service fee.

I've studied Audi's telematics architecture. Its factory-installed SIM card is pre-embedded in the communication module, primarily supporting Audi Connect services. Legally speaking, the EU mandates that vehicles produced after 2018 must be equipped with eCall emergency calling functionality, which relies on this original card. However, for other services like connected entertainment and remote control, you can completely use your mobile hotspot as an alternative. It's worth noting that for certain premium models equipped with matrix headlights, the OTA lighting upgrade function has higher demands on network stability, making the factory SIM card more reliable in such cases.
