This is the exact OneCarStereo Cloud AI Box I tested in the video, and the standout feature is Cloud SIM—no physical SIM card needed. I linked it by QR code, bought a plan, and it automatically connected on 4G and shut off Wi‑Fi, which is the kind of convenience people actually want for streaming and navigation.

Pros

  • +Cloud SIM option means no physical SIM card required
  • +Automatic carrier selection for a stronger connection in the background
  • +Runs popular apps like Netflix, YouTube, and Maps
  • +Split screen support (ex: YouTube + Maps)
  • +Includes optional 12V power adapter for vehicles with weak USB power

Cons

  • -Some audio/video sync delay is still noticeable (varies by vehicle/app)
  • -After the vehicle sat, I sometimes had to re-activate Cloud SIM while connected to Wi‑Fi
  • -Compatibility/experience on non-touchscreen infotainment systems is unclear
