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.

Basic perception functions (like Adaptive Cruise Control ACC, Lane Keeping Assist LKA, and Automatic Emergency Braking AEB) rely on the vehicle's local radar and cameras, and can operate normally overseas. However, advanced features that heavily depend on high-precision maps and cloud data (like Navigation on Autopilot NOA and Full Self-Driving FSD) cannot be activated overseas.

Under CIF (Cost, Insurance, and Freight) terms, we will insure your vehicle with a reputable international insurance company for "All Risks" before shipment. If total loss or partial damage occurs during sea transport, the risk transfers to you once the goods cross the ship's rail. However, sellwellauto will not stand by; we will assist you in preparing complete claims documentation (such as the bill of lading, invoice, and damage photos) to initiate a cross-border claim process with the insurance company, minimizing your financial loss.
