A realistic timeline: sourcing and negotiation 3-7 days; deposit and booking 1-2 days; pre-shipment inspection 2-4 days; export clearance and vessel booking 7-14 days; sea freight 2-5 weeks depending on destination; import customs clearance and port release 5-10 days. Overall, plan for roughly 5-8 weeks from order to port of destination by sea. For Central Asia and Russia by rail, 2-3 weeks total is common. Tips: ask the exporter for a written schedule with milestones (inspection done, customs cleared, vessel loaded, ETA); track the vessel yourself once you have the container or booking number; and remember Chinese holidays — Chinese New Year and Golden Week can add 1-2 weeks of delay.

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.

Testing is mandatory. Troubleshooting electrical devices in the car is part of the standard procedure. We will test the window lift motors, mirror folding, air conditioning compressor and fan, electric seat tracks, etc. Any stuttering or failure of electronic components will be recorded.
