Most leading Chinese brands' car systems support "offline voice commands" (like adjusting temperature and opening windows). However, if recognition fails due to accent or language limitations (only standard Chinese is supported), you can always control it via the physical screen.

Most new car manufacturers' e-SIMs are directly soldered onto the T-Box motherboard (surface-mounted) and cannot be removed and replaced like a phone. Unauthorized desoldering of the motherboard may cause complete communication failure in the vehicle, and we strictly prohibit this operation.

We must inform you objectively: Most Chinese car manufacturers' connected services (cloud servers) are restricted by data security regulations and overseas network limitations. Once the vehicle leaves China, the factory-installed SIM card will become inactive. This means that official OTA upgrades and factory mobile app remote controls (like pre-cooling the car or unlocking doors) typically cannot be used overseas. The vehicle will operate as a standalone version, but this will not affect basic driving and physical button functions.
